1021 the “Adaptive Replacement Cache” (ARC) of the “Zeta File-System”
1022 (ZFS). Thanks to Anthony Dewhurst for the patch.
1023 * empty_counter match: The new Empty Counter match matches value
1024 lists, where at least one data source is of type COUNTER and the
1025 counter value of all counter data sources is zero.
1027 2009-12-18, Version 4.7.5
1028 * Build system, java plugin: Don't use “find -L” to search for Java
1029 headers, because it's a GNU extension.
1030 * Build system: Support for parallel builds has been improved. Thanks
1031 Sebastian Harl and Stefan Völkel for looking into this.
1032 * collectd: Print error messages to STDERR if no log plugin has been
1034 * memory plugin: Handling of >4 Gbyte of memory has been fixed.
1035 * network plugin: The license has been changed to LGPL 2.1.

1040 containing control characters are now interpreted as hex-strings.
1041 * unixsock plugin: A memory leak in the LISTVAL command has been
1042 fixed. Thanks to Ben Knight for his patch.
1044 2009-10-03, Version 4.7.4
1045 * Build system: Issues when building the iptables plugin have been
1047 * exec plugin: Clear the signal block mask before calling exec(2).
1048 * perl plugin: Declare the “environ” variable. This solves build
1049 issues on some platforms.
1050 * processes plugin: Remove unnecessary call of realloc(3). Thanks to
1051 Andrés J. Díaz for the patch.
1052 * unixsock plugin: Fix a (well hidden) race condition related to file
1053 descriptor handling.
1055 2009-09-13, Version 4.7.3
1056 * collectd: Fix a possible but very rare invalid “free” in the caching
1057 code. Thanks to Sebastian Harl for the patch.
1058 * collectd: Remove old values when a cache entry is marked as missing.

1062 * collectd: The “plugin_unregister_read” function has been fixed.
1063 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
1064 to follow redirects. Thanks to Joey Hess for reporting this bug.

1071 is linked with the shipped library, too.
1072 * java plugin: Delay creating the JVM until after the daemon has
1073 forked. The JVM internally creates threads that are lost when
1074 forking. This means that Java-based plugins are now configured
1075 during the init-phase, i. e. later than other plugins.
1076 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
1077 to Alan Pevec for the patch.
1078 * network plugin: Fix the handling of the “CacheFlush” option: The

1100 details have been added to the configuration summary. Support for
1101 libtool 2.2 has been added.
1102 * collectd: Two bugs with the threshold checking have been fixed. The
1103 first one prevented thresholds to be checked at all, the second one
1104 caused wrong behavior with the persistency option. Thanks to Andrés
1105 J. Díaz for fixing these problems.
1106 * collectd: Handling of the `Include' configuration option has been
1108 * rrdtool plugin: Make sure initialization is run only once. This
1109 resolves problems under Solaris and potentially other systems.
1110 Thanks to Amit Gupta for reporting this bug.
1111 * java plugin: Make it possible to use dots ('.') instead of slashes
1112 ('/') as the class separator. Thanks to Randy Rizun for pointing

1128 multicast traffic from Ganglia's gmond daemon.
1129 * java plugin: The new java plugin exports the collectd API to Java,
1130 making it possible to write extensions to collectd in Java.
1131 * memcachec plugin: The new memcachec plugin queries data from a
1132 memcached daemon and parses it similar to the cURL plugin. Thanks to
1133 Doug MacEachern for the initial code.

1150 structured files, such as many files beneath /proc.
1151 * ted plugin: The new TED plugin reads power consumption measurements
1152 from “The Energy Detective” (TED). Thanks to Eric Reed for this
1154 * onewire plugin: The new `Interval' option allows collecting
1155 information from OneWire sensors at arbitrary intervals.
1156 * ping plugin: Support for collecting the drop rate and standard
1157 deviation of round-trip times has been added.

1191 * Build system, various plugins: Many build fixes for FreeBSD,
1192 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1193 for many fixes and providing a build system for many platforms,
1194 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1195 providing an OpenBSD system.
1196 * collectd: Two bugs with the threshold checking have been fixed. The
1197 first one prevented thresholds to be checked at all, the second one
1198 caused wrong behavior with the persistency option. Thanks to Andrés
1199 J. Díaz for fixing these problems.
1200 * collectd: Handling of the `Include' configuration option has been

1216 * filter subsystem: Allow `Chains' without default targets.
1217 * liboping: A patch to comply with strict aliasing rules has been
1219 * timediff match: Fix a typo: The match was registered with a wrong
1220 name which prevented this match to be used as documented. Thanks to
1221 Bruno Prémont for finding this problem.
1222 * bind plugin: Fix collection of the cached RR sets. The number of RR
1223 sets currently in the cache was collected as a counter value, which
1224 is nonsense. Thanks to Bruno Prémont for implementing this.
1225 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
1226 primarily BSDs, don't take it well and crash.
1227 * oracle plugin: Portability to 64 bit systems has been improved.
1228 * postgresql plugin: The default configuration has been improved.
1229 * rrdtool plugin: Fix a possible race condition: If the network plugin

1238 for finding and fixing most of them.
1239 * ipmi plugin: Fix an off-by-one error which could cause segmentation
1240 faults. Thanks to Peter Holik for his patch.
1242 2009-02-16, Version 4.6.0
1243 * collectd: Added the `filter chain' infrastructure, which allows the
1244 user to use `matches' and `targets' to control value processing.
1245 * collectd: The new `-T' command line argument allows more in-depth
1246 testing of a configuration. Thanks to Doug MacEachern for the patch.
1247 * collectd-nagios: The Nagios integration command has been updated to

1261 statistics, allowing very detailed name server statistics. Thanks to
1262 Bruno Prémont for this plugin.
1263 * cpu plugin: Report `interrupt' separately when using
1264 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
1265 example for native OpenBSD support, has been added. Thanks to Simon
1266 Kuhnle for the patch.
1267 * csv plugin: Make it possible to write values to STDOUT instead of
1268 files. This is meant for testing purposes mostly. The output written
1269 to STDOUT is compatible with the exec plugin. Thanks to Doug
1270 MacEachern for the patch.
1271 * curl plugin: This new plugin can be used to read web pages and parse
1272 them using the same mechanism that's used in the tail plugin.
1273 * dbi plugin: This new plugin allows you to connect to a variety of
1274 relational databases and use SQL to gather custom statistics from
1275 it. It is similar to the already existing PostgreSQL plugin but uses
1276 libdbi to communicate with the database(s).
1277 * interface plugin: Use the ignorelist framework when selecting /
1278 ignoring interfaces. This allows one to use regular expressions to
1279 select interfaces, too.
1280 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
1281 Thanks to Bruno Prémont for this patch.
1282 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

1295 * perl plugin: Export the newly added plugin_write() to Perl plugins.
1296 * perl plugin: Added support for `notification meta data'.
1297 * perl plugin: Added support for the `filter chain' infrastructure by
1298 allowing plugins to register `matches' and `targets'.
1299 * postgresql plugin: The preferred configuration syntax has been
1300 updated to be in line with the syntax used by the new dbi and oracle
1301 plugins. The compatibility code for the old syntax is present.
1302 Support for the new `Result' blocks and the interval parameter has
1304 * processes plugin: Stacksize and virtual memory usage statistics have
1305 been added. Portability fixes.
1306 * rrdcached plugin: This new plugin uses the (still in development)
1307 RRD accelerator daemon, rrdcached. This daemon works very similar to
1308 the original rrdtool plugin of collectd, but adds some more nice
1310 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
1313 2009-05-09, Version 4.5.4
1314 * Build system, various plugins: Many build fixes for FreeBSD,
1315 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
1316 for many fixes and providing a build system for many platforms,
1317 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
1318 providing an OpenBSD system.

1325 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
1326 Tomasz Pala for the patch.
1327 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
1329 * rrdtool plugin: Fix a possible race condition: If the network plugin
1330 is initialized and dispatches a value before the rrdtool plugin is
1331 initialized, the daemon may crash.
1332 * memory plugin: Fix a potential problem under Solaris.
1334 2009-02-22, Version 4.5.3
1335 * build system: The check for libupsclient even when `pkg-config' is

1344 code. Thanks to "thated" for reporting this.
1346 2009-01-02, Version 4.5.2
1347 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1348 file may be in both locations, especially when the database was
1349 installed in a non-standard path. Thanks to Dusty Doris for
1351 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1352 Solaris, in the configure script automatically.
1353 * build system, tcpconns plugin: Check for `kvm_nlist' and
1354 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
1355 library with similar functions to the BSD variant, but doesn't
1356 provide these necessary functions.
1357 * collectd.conf(5): Various fixes and clarifications.
1358 * collectd: Remove a GNUism (unnamed unions), thus improving
1360 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
1361 This solves portability problems, especially for Solaris.
1362 * dns plugin: Fix a portability problem with NetBSD.
1363 * filecount plugin: Fix an off-by-one error. This error may cause a
1365 * network plugin: Fix the handling of `type' in the network protocol.
1366 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1367 much larger buffer. This caused the `type' to be transferred much
1368 more often than necessary. In some cases, e. g. the `cpu' and
1369 `cpufreq' plugins being used at the same time, data may be corrupted
1370 in those files. Thanks to Bruno Prémont for debugging and reporting
1372 * processes plugin: Fix a possible segmentation fault when specifying
1373 invalid configuration options.
1374 * unixsock plugin: Make sure the initialization function is run only
1375 once. This resolves a file descriptor leak under systems which run
1376 the initialization more than once, such as Solaris.
1378 2008-10-16, Version 4.5.1
1379 * build system: Change `--enable-<plugin>' to abort with an error if
1380 dependencies are not met. Thanks to Bruno Prémont for the patch.
1381 Also, the poisoning of various string functions has been restricted
1383 * collectd: Fix a memory leak in the global value cache. With every
1384 *missing* value a couple of bytes would be leaked. Another memory
1385 leak in the configuration handling code has been fixed. Thanks to
1386 Niraj Tolia for reporting these issues.
1387 * collectd: Fix an off-by-one error in the ignorelist functionality.
1388 When using regular expressions, the last character would be missing,
1389 possibly matching differently from what one would expect.
1390 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1392 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1393 Linzberger for reporting the bug.
1394 * iptables plugin: Fix an off-by-one error. If a string was just one
1395 character too long, it was truncated instead of reporting an error.
1396 * network plugin: Fix a memory leak in the configuration handling
1397 code. Thanks to Niraj Tolia for reporting this issue.
1398 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1399 * postgresql plugin: Don't reopen connection during reinitialization.
1400 This fixes a bug under Solaris and potentially other platforms.
1401 Missing calls to `PQclear' have been added, too. This fixes memory
1402 leaks. Thanks to ``Admin'' for reporting these bugs.
1403 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
1405 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1406 problems with some `libc's. Thanks to Matthias Lay for reporting the
1409 2008-09-04, Version 4.5.0
1410 * collectd: Added the ability to flush certain identifiers.
1411 * collectd: The concept of `notification meta data' has been
1413 * filecount plugin: The new filecount plugin counts the number of
1414 files in a directory and its subdirectories.
1415 * ipmi plugin: Sensor names have been changed to ensure unique names.
1416 Notifications upon added and removed sensors can now be generated.
1417 * notify_desktop plugin: This new plugin sends notifications to the
1418 X desktop using the structure defined in the `Desktop Notification
1420 * notify_email plugin: This new plugin sends out notifications via
1421 email, using the `esmtp' library.
1422 * onewire plugin: The new experimental(!) onewire plugin reads values,
1423 such as temperatures, from sensors connected to the computer via the
1425 * perl plugin: Improved synchronized access to internal data structures
1426 and fixed a possible dead-lock.
1427 * perl plugin: Added the ability to flush certain identifiers and marked
1428 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
1430 * perl plugin: Added the ability to configure Perl plugins.
1431 * postgresql plugin: The new postgresql plugin collects statistics
1432 about or from a PostgreSQL database.
1433 * processes plugin: The `ProcessMatch' option has been added.
1434 * rrdtool plugin: Implement throttling of the `update queue' to lessen
1436 * tcpconns plugin: This plugin has been ported to OpenBSD.
1437 * thermal plugin: The new thermal plugin collects system temperatures
1438 using Linux ACPI thermal zone data.
1440 2009-01-02, Version 4.4.5
1441 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
1442 file may be in both locations, especially when the database was
1443 installed in a non-standard path. Thanks to Dusty Doris for
1445 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
1446 Solaris, in the configure script automatically.
1447 * collectd.conf(5): Various fixes and clarifications.
1448 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
1449 portability problems, especially for Solaris.
1450 * dns plugin: Fix a portability problem with NetBSD.
1451 * network plugin: Fix the handling of `type' in the network protocol.
1452 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1453 much larger buffer. This caused the `type' to be transferred much
1454 more often than necessary. In some cases, e. g. the `cpu' and
1455 `cpufreq' plugins being used at the same time, data may be corrupted
1456 in those files. Thanks to Bruno Prémont for debugging and reporting
1458 * unixsock plugin: Make sure the initialization function is run only
1459 once. This resolves a file descriptor leak under systems which run
1460 the initialization more than once, such as Solaris.
1462 2008-10-16, Version 4.4.4
1463 * build system: Change `--enable-<plugin>' to abort with an error if
1464 dependencies are not met. Thanks to Bruno Prémont for the patch.
1465 Also, the poisoning of various string functions has been restricted
1467 * collectd: Fix a memory leak in the global value cache. With every
1468 *missing* value a couple of bytes would be leaked. Another memory
1469 leak in the configuration handling code has been fixed. Thanks to
1470 Niraj Tolia for reporting these issues.
1471 * collectd: Fix an off-by-one error in the ignorelist functionality.
1472 When using regular expressions, the last character would be missing,
1473 possibly matching differently from what one would expect.
1474 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1476 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1477 Linzberger for reporting the bug.
1478 * network plugin: Fix a memory leak in the configuration handling
1479 code. Thanks to Niraj Tolia for reporting this issue.
1480 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1481 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1482 problems with some `libc's. Thanks to Matthias Lay for reporting the
1485 2008-09-01, Version 4.4.3
1486 * collectd: Fix a memory leak in the threshold checking code.
1487 * memcached plugin: Fix a too short timeout and a related file
1489 * memory plugin: A typo in the libstatgrab code has been fixed.
1490 * snmp plugin: Fix a possible memory leak.
1492 2008-07-15, Version 4.4.2
1493 * build system: Use pkg-config to detect the upsclient library.
1494 * collectd: Try even harder to determine the endianess of the
1495 architecture collectd is being built on.
1496 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1498 * dns plugin: Fix compilation errors with BIND versions 19991001
1500 * network plugin: Bugfix in the init routine: The init function
1501 cleared a buffer regardless of its contents. This could lead to lost
1502 values under Solaris.
1503 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1504 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1506 * wireless plugin: Work around incorrect noise and power values
1507 returned by some broken drivers.
1509 2008-06-03, Version 4.4.1
1510 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1511 to kyrone for reporting this.
1512 * collectd: Fixed min/max output in notifications generated by
1514 * collectd-nagios: Fix the protocol used to communicate with the
1516 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1517 initialization has errors. An issue with Perl 5.10 has been fixed.
1518 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1519 René Rebe and Siegmund Gorr for reporting this.
1521 2008-05-06, Version 4.4.0
1522 * collectd: Internal code cleanups.
1523 * collectd: Added support for a `Flush' command in the unixsock and
1524 exec plugins. This command can be used to force a plugin (or all) to
1525 flush its values to disk.
1526 * collectd: Thresholds can now be configured to apply to one data
1527 source only, making it possible to configure different thresholds
1528 for each data source.
1529 * apache, nginx plugins: Added the possibility to disable host and/or
1531 * ascent plugin: The new ascent plugin reads and parses the statistics
1532 page of an Ascent server.
1533 * cpu plugin: Support for the statgrab library has been added.
1534 * disk plugin: The possibility to ignore certain disks or collect only
1535 specific disks has been added.
1536 * disk plugin: Support for the statgrab library has been added.
1537 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1538 sensor values via IPMI, the intelligent platform management
1540 * iptables plugin: The iptc library that is used by the iptables
1541 plugin has been added to the distribution, because it is not
1542 provided by all distributions and removed from at least one.
1543 * powerdns plugin: The new powerdns plugin reads statistics from an
1544 authoritative or a recursing PowerDNS name server.
1545 * rrdtool plugin: The size of the files generated with the default
1546 configuration has been decreased.
1547 * tail plugin: The new tail plugin can be used to gather statistics by
1548 continuously reading from log files.
1549 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1550 TeamSpeak2 server and collects statistics about the number of users
1551 and number of channels.
1552 * users plugin: Support for the statgrab library has been added.
1553 * vmem plugin: The new vmem plugin collects very detailed statistics
1554 about the virtual memory subsystem of Linux.
1556 2008-08-30, Version 4.3.4
1557 * Build system: Improved detection of and linking with the statgrab
1559 * collectd: Portability fixes, especially to determine endianess more
1561 * Various plugins: Fix format strings.
1562 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1563 again has been applied.
1564 * memcached plugin: Fix a too short timeout and a related file
1566 * memory plugin: A typo in the libstatgrab code has been fixed.
1567 * network plugin: A fix in the initialization function solves problems
1569 * nginx plugin: A thread-unsafe function has been replaced.
1570 * vserver plugin: A thread-unsafe function has been replaced.
1571 * wireless plugin: A work-around for broken wireless drivers has been
1574 2008-04-22, Version 4.3.3
1575 * build system: Improved detection of several libraries, especially if
1576 they are in non-standard paths.
1577 * build system: Portability fixes: Automatically define "_REENTRANT"
1578 if the libc expects it.
1579 * collectd: Error and warning messages have been improved.
1580 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1582 * apache plugin: Allocate new memory when reading a webpage instead of
1583 using a buffer of static size.
1584 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1586 * hddtemp plugin: Error and warning messages have been improved.
1587 * sensors plugin: Fix sensor collection for some chip types.
1589 2008-03-29, Version 4.3.2
1590 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1591 `Persist' threshold options.
1592 * collectd: Fix handling of missing values in the global value cache.
1593 * collectd: Improved error messages when parsing the configuration.
1594 * sensors plugin: Fix temperature collection with libsensors4.
1595 * unixsock plugin: Fix mixed input and output operation on streams.
1596 * wireless plugin: Fix reading noise value.
1598 2008-03-05, Version 4.3.1
1599 * exec plugin: Set supplementary group IDs.
1601 + Use `memcpy' when constructing/parsing a package to avoid
1602 alignment problems on weird architectures, such as Sparc.
1603 + Translate doubles to/from the x86 byte representation to ensure
1604 cross-platform compatibility.
1605 * ping plugin: Correct the handling of the `TTL' setting.
1606 * swap plugin: Reapply a patch for Solaris.
1607 * tcpconns plugin: Portability improvements.
1609 2008-02-18, Version 4.3.0
1610 * collectd: Notifications have been added to the daemon. Notifications
1611 are status messages that may be associated with a data instance.
1612 * collectd: Threshold checking has been added to the daemon. This
1613 means that you can configure threshold values for each data
1614 instance. If this threshold is exceeded a notification will be
1616 * collectd: The new `FQDNLookup' option tells the daemon to use the
1617 full qualified domain name as the hostname, not just the host part
1618 es returned by `gethostname(2)'.
1619 * collectd: Support for more than one `TypesDB' file has been added.
1620 This is useful when one such file is included in a package but one
1621 wants to add custom type definitions.
1622 * collectd: The `Include' config option has been expanded to handle
1623 entire directories and shell wildcards.
1624 * collectdmon: The new `collectdmon' binary detects when collectd
1625 terminates and automatically restarts it again.
1626 * csv plugin: The CSV plugin is now able to store counter values as a
1627 rate, using the `StoreRates' configuration option.
1628 * exec plugin: Handling of notifications has been added and the
1629 ability to pass arguments to the executed programs has been added.
1630 * hddtemp plugin: The new `TranslateDevicename' option lets you
1631 disable the translation from device names to major-minor-numbers.
1632 * logfile plugin: Handling of notifications has been added.
1633 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1634 domain name lookups in this plugin.
1635 * perl plugin: Many internal changes added support for handling multiple
1636 threads making the plugin reasonably usable inside collectd. The API has
1637 been extended to support notifications and export global variables to
1638 Perl plugins; callbacks now have to be identified by name rather than a
1639 pointer to a subroutine. The plugin is no longer experimental.
1640 * uuid plugin: The new UUID plugin sets the hostname to an unique
1641 identifier for this host. This is meant for setups where each client
1642 may migrate to another physical host, possibly going through one or
1643 more name changes in the process. Thanks to Richard Jones from
1644 Red Hat's Emerging Technology group for this plugin.
1645 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1646 CPU, disk and network statistics about guest systems on the same
1647 physical server. Thanks to Richard Jones from Red Hat's Emerging
1648 Technology group for this plugin.
1650 2008-04-22, Version 4.2.7
1651 * build system: Improved detection of several libraries, especially if
1652 they are in non-standard paths.
1653 * build system: Portability fixes: Automatically define "_REENTRANT"
1654 if the libc expects it.
1655 * collectd: Error and warning messages have been improved.
1656 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1658 * apache plugin: Allocate new memory when reading a webpage instead of
1659 using a buffer of static size.
1660 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1662 * hddtemp plugin: Error and warning messages have been improved.
1663 * sensors plugin: Fix sensor collection for some chip types.
1665 2008-03-29, Version 4.2.6
1666 * collectd: Improved error messages when parsing the configuration.
1667 * sensors plugin: Fix temperature collection with libsensors4.
1668 * unixsock plugin: Fix mixed input and output operation on streams.
1669 * wireless plugin: Fix reading noise value.
1671 2008-03-04, Version 4.2.5
1672 * apache plugin: Improved initialization and error messages.
1673 * exec plugin: Set supplementary group IDs.
1675 + Create separate threads for reading from the socket and parsing
1676 and dispatching incoming packets. Versions prior to this may have
1677 problems in high-load situations, where the socket receive buffers
1678 overflows, resulting in gaps in the data.
1679 + Use `memcpy' when constructing/parsing a package to avoid
1680 alignment problems on weird architectures, such as Sparc.
1681 + Translate doubles to/from the x86 byte representation to ensure
1682 cross-platform compatibility.
1683 * ping plugin: Correct the handling of the `TTL' setting.
1684 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1685 * swap plugin: Reapply a patch for Solaris.
1686 * tcpconns plugin: Portability improvements.
1688 2008-01-21, Version 4.2.4
1689 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1690 the permission on the socket as documented in the manpage. Thanks to
1691 Evgeny Chukreev for fixing this issue.
1692 * collectd: The documentation has been improved.
1694 2007-12-28, Version 4.2.3
1695 * sensors plugin: Updated the plugin to build and work with version 3
1696 of the libsensors library.
1698 2007-12-15, Version 4.2.2
1699 * nginx plugin: Incorrect comparison of strings lead to a segfault
1700 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1702 * logfile plugin: The config option `Timestamp' was handled
1703 incorrectly and basically always active. Thanks to Luke Heberling
1706 2007-11-08, Version 4.2.1
1707 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1708 enabled on the host.
1709 * snmp plugin: Fix a memory leak.
1711 2007-10-27, Version 4.2.0
1712 * collectd: The new config option `Include' lets you include other
1713 configfiles and thus split up your config into smaller parts. This
1714 may be especially interesting for the snmp plugin to keep the data
1715 definitions separate from the host definitions.
1716 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1717 (number of connections, octets and packets for each service and
1718 destination). Thanks to Sebastian Harl for this plugin.
1719 * memcached plugin: The new `memcached' plugin connects to a memcached
1720 daemon process and collects statistics of this distributed caching
1721 system. Thanks to Antony Dovgal for contributing this plugin.
1722 * nginx plugin: The new `nginx' plugin reads the status page of an
1723 nginx daemon and saves the handled connections and requests.
1724 * perl plugin: Many changes, including the added `EnableDebugger'
1725 config option which lets you debug your Perl plugins more easily.
1726 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1727 be more thread-safe otherwise by locking calls to the library.
1728 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1729 correct the values returned by SNMP-agents. If a <data> block is
1730 defined as `table' the instance is now optional. The sequence number
1731 is used as the type-instance in this case. The new `InstancePrefix'
1732 option allows to add arbitrary prefixes to the type-instance.
1733 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1734 certain TCP connections and what state they're in. This can be used
1735 to see how many connections your FTP server has to handle or how
1736 many outgoing connections your mailserver has open.
1738 2008-01-11, Version 4.1.6
1739 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1740 the permission on the socket as documented in the manpage. Thanks to

1748 of the libsensors library.
1750 2007-11-08, Version 4.1.4
1751 * Build system: Improve detection of the rrd library, especially if
1752 it's in a non-standard location.
1753 * Build system: A bug when parsing the argument for
1754 `--with-libnetsnmp' has been fixed.
1755 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1756 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1757 a deadlock or delay when shutting down the daemon.
1758 * snmp plugin: Fix a memory leak.
1760 2007-10-24, Version 4.1.3
1761 * collectd: A build issue under Solaris has been resolved by renaming
1763 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1764 be more thread-safe otherwise by locking calls to the library.
1766 2007-09-28, Version 4.1.2
1767 * apcups plugin: Fix reporting of the `load percent' data.
1768 * wireless plugin: Correct the handling of cards returning signal and
1769 noise quality as percentage.
1770 * perl plugin: Fix a possible buffer overflow in get_module_name().
1771 * build system: Further improve the detection of libraries.
1772 * netlink plugin: Build issues under some older versions of the Linux
1773 includes (i. e. Debian Sarge) have been fixed.
1774 * snmp plugin: Fix a potential segfault when a host times out. Add
1775 support for the `timeticks' type.
1777 2007-09-12, Version 4.1.1
1778 * Build system: The detection of `libnetlink' has been improved.
1779 * collectd: The documentation has been fixed in numerous places.
1780 * exec plugin: Setting the group under which to run a program has been
1782 * collectd: The `sstrerror' function was improved to work correctly
1783 with the broken GNU version of `strerror_r'.
1784 * collectd: Write an error message to STDERR when loading of a plugin
1786 * apcups plugin: Fix the `types' used to submit the values: They still
1787 has an `apcups_' prefix which doesn't work anymore.
1788 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1789 whatever the client thinks is `now'..
1791 2007-09-01, Version 4.1.0
1792 * Build system: The build system has been changed to automatically
1793 disable all plugins, which are missing dependencies. The dependency
1794 checking has been removed from the plugins themselves to remove
1796 * Flexible interval: The interval of collected data is now sent along
1797 with the data itself over the network, so that the interval-settings
1798 of server and clients no longer needs to match.
1799 * netlink plugin: The new `netlink' plugin connects to the Linux
1800 kernel using a netlink socket and uses it to query information about
1801 interfaces, qdiscs and classes.
1802 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1803 to not block data collection.
1804 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1805 network devices, such as switches, routers, thermometers, rack
1806 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1808 * unixsock plugin: Added the `LISTVAL' command.
1809 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1810 of music played with xmms.
1812 2007-09-28, Version 4.0.9
1813 * apcups plugin: Fix reporting of the `load percent' data.
1814 * wireless plugin: Correct the handling of cards returning signal and
1815 noise quality as percentage.
1816 * perl plugin: Fix a possible buffer overflow in get_module_name().
1818 2007-09-12, Version 4.0.8
1819 * collectd: The `sstrerror' function was improved to work correctly
1820 with the broken GNU version of `strerror_r'.
1821 * collectd: Write an error message to STDERR when loading of a plugin
1823 * apcups plugin: Fix the `types' used to submit the values: They still
1824 has an `apcups_' prefix which doesn't work anymore.
1825 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1826 whatever the client thinks is `now'..
1828 2007-08-26, Version 4.0.7
1829 * documentation: Some typos have been fixed and some information has
1831 * build system: Many fixes for detecting libraries in unusual places,
1832 such as on RedHat systems. The affected libraries are `libcurl',
1833 `libmysql', and `libupsclient'.
1834 * network plugin: Allow the `Port' option to be specified as a number
1835 (i. e. without quotes).
1836 * nut plugin: A fix allows linking the nut plugin against
1837 libupsclient, version >= 2.2.0.
1838 * processes plugin: Fix a potential segmentation fault.
1840 2007-07-30, Version 4.0.6
1841 * sensors plugin: Fix the ignorelist functionality: Only the `type
1842 instance' was used to match against the list, but the documentation
1843 told otherwise. This release fixes the code, so it complies with the
1845 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1846 configuration messages will end up in the logging facility.
1847 * conrtib/fedora: The contributed specfile for Fedora has been
1850 2007-07-05, Version 4.0.5
1851 * Portability: More fixes for OpenBSD have been included.
1853 2007-06-24, Version 4.0.4

1861 2007-06-19, Version 4.0.3
1862 * cpu plugin: Fix the Darwin / Mac OS X code.
1863 * ping plugin: Use the return value of `getpid', not its address.
1864 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1865 initialized correctly.
1866 * configure: Added `--with-nan-emulation' to aid cross compilation.
1868 2007-06-12, Version 4.0.2
1869 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1870 they're given in numerically form.
1872 2007-06-07, Version 4.0.1
1873 * iptables plugin: A bug in the configuration routine has been fixed.
1874 Setting a comment in the configfile will no longer cause a
1877 2007-06-03, Version 4.0.0
1878 * collectd: The plugin-infrastructure has been changed to allow for
1879 more types of plugins, namely `write' and `log' plugins.
1880 * collectd: The read-function has been changed to read many plugins in
1881 parallel, using threads. Thus, plugins generally need to use
1882 thread-safe functions from now on.
1883 * collectd: The '-t' command line options allows to perform syntax tests
1884 of the configuration file and exit immediately.
1885 * csv plugin: The new `csv' plugin handles output to `comma separated
1887 * rrdtool plugin: The new `rrdtool' plugin handles output to
1888 RRD-files. Data can be cached to combine multiple updates into one
1889 write to increase IO-performance.
1890 * network plugin: The new `network' plugin handles IO via the network.
1891 It implements a different, much more extensible protocol which can
1892 combine many values in one packet, decreasing the number of UDP-
1893 packets being sent. It can read from and send to the network and
1894 with the appropriate configuration even forward packets to other
1896 * unixsock plugin: The new `unixsock' plugin provides an interface to
1897 communicate with the daemon while it is running. Right now the
1898 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1900 * perl plugin: The new `perl' plugin allows you to write extensions
1901 for collectd in the scripting-language Perl.
1902 * logfile plugin: The new `logfile' plugin writes logmessages to files
1903 or STDOUT or STDERR.
1904 * syslog plugin: The new `syslog' plugin sends logmessages to the
1905 system's syslog daemon.
1906 * entropy plugin: The new `entropy' plugin collects the amount of
1907 entropy currently being available to the system.
1908 * exec plugin: The new `exec' plugin forks child processes and reads
1909 back values provided by the forked processes.
1910 * iptables plugin: The new `iptables' plugin reads counters from
1911 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1913 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1914 to Peter Holik for contributing this plugin.
1915 * nut plugin: The new `nut' plugin connects the upsd of the `network
1916 ups tools' and reads information about the connected UPS.
1917 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1918 connections) field was added by Florent Monbillard.
1919 * collectd-nagios: The new `collectd-nagios' binary queries values
1920 from collectd, parses them and exits according to Nagios-standards.
1921 * manpages: The manpages have been improved a lot.
1923 2007-09-28, Version 3.11.7
1924 * wireless plugin: Correct the handling of cards returning signal and
1925 noise quality as percentage.
1927 2007-08-31, Version 3.11.6
1928 * processes plugin: Fix a potential segmentation fault.
1930 2007-05-29, Version 3.11.5
1931 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1932 * ntpd plugin: Fix a potential buffer overflow.
1933 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1934 were accounted as `zombies'.
1936 2007-04-10, Version 3.11.4
1937 * dns plugin: Change the order of includes to make the plugin compile
1940 2007-03-30, Version 3.11.3
1941 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1942 of the unused `COLLECT_KSTAT'.
1944 2007-02-11, Version 3.11.2
1945 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1946 NULL-pointer may have been passed to `printf' which causes a
1947 segfault with some libcs.
1949 2007-02-10, Version 3.11.1
1950 * df plugin: Some wrong defines have been fixed so the plugin works
1951 under Solaris again.
1952 * dns plugin: The usage of a struct has been fixed to work with
1954 * processes plugin: Some missing defines have been added so the plugin
1955 compiles cleanly under FreeBSD and presumably other UNIXes.
1957 2006-12-22, Version 3.11.0
1958 * collectd: The new command line option `-P' makes it easier for
1959 distributors to change the location of PID-files.
1960 * collectd: The daemon shuts down faster now which makes it easier to
1961 write init.d-scripts for it.
1962 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1963 caused problems every now and then.
1964 * df plugin: New config options allow to ignore certain mountpoints,
1965 filesystem types or devices.
1966 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1967 and interprets it. It collects traffic as well as qtype, opcode and
1969 * email plugin: Sebastian Harl has contributed this plugin which
1970 counts received mails in categories (e. g. ham, spam, virus), spam
1971 score (as given by SpamAssassin) and check types.
1972 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1973 uses `mbmon' to gather information from sensors on the motherboard.
1974 * processes plugin: Collect detailed statistics for configured
1975 processes, that's process and thread count, CPU usage, resident
1976 segment size and pagefaults.
1977 * multimeter plugin: Peter Holik contributed a new plugin which
1978 queries multimeters.
1979 * sensors plugin: Lubos Stanek has put much effort into improving this
1980 plugin, including `extended naming', collection of voltage values
1981 and the possibility to ignore certain values.
1983 2006-12-21, Version 3.10.4
1984 * Max Kellermann has identified a bug in the server routine: When
1985 opening a socket fails the daemon will (re)try opening the socket in
1986 an endless loop, ultimately leading to a `EMFILE' error.
1988 2006-11-04, Version 3.10.3
1989 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1990 ntpd's reply was sent in more than one packet, the buffer size was
1991 calculated incorrectly, resulting in the reading of uninitialized or
1994 2006-11-01, Version 3.10.2
1995 * The sample config file has been improved.
1996 * Errors in the manpages have been corrected.
1997 * The ping-plugin now adds hosts during initialization, not during
1998 startup. This speeds up startup when no network connectivity is
1999 available. Also, the hosts are being added later when the network is
2001 * Improved BSD-support for the df-plugin.
2002 * Fixed syntax errors in the swap-plugin for Mac OS X.
2003 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
2005 * Don't disable the mysql-plugin if connecting to the database fails
2006 during initialization. Instead, try again in increasing intervals.
2008 2006-07-19, Version 3.10.1
2009 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
2010 the apcups cannot be reached, unconnected sockets will pile up and
2011 eventually lead to `Too many open files' errors.
2013 2006-07-09, Version 3.10.0
2014 * The `disk' plugin has been ported to Darwin.
2015 * The `battery' plugin should work on many Apple computers now.
2016 * The `traffic' plugin can now ignore certain interfaces. Also,
2017 statistics for sent/received packets and errors have been added.
2018 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
2019 to Anthony Gialluca for contributing this plugin and providing me
2020 with a test environment :)
2021 * A plugin for monitoring an NTP instance and the local clock drift
2024 2006-06-25, Version 3.9.4
2025 * The Solaris code in the `swap' plugin has been changed to reflect
2026 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
2028 * The debugging system has been fixed to work with the Sun libc.
2029 * When built without librrd the variable `operating_mode' could be
2030 uninitialized. Thanks to David Elliot for reporting the bug.
2032 2006-06-01, Version 3.9.3
2033 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
2034 operating systems also profit from the changes, but I wasn't able to
2036 * Changed the build system to find the netinet-includes under FreeBSD
2037 and therefore successfully build the `liboping' library there.
2039 2006-05-09, Version 3.9.2
2040 * Applied a patch to the `liboping' library. Due to a bug in the
2041 sequence checking the `ping' plugin stopped working after
2042 approximately 7.6 days.
2044 2006-05-09, Version 3.8.5
2045 * Applied a patch to the `liboping' library. Due to a bug in the
2046 sequence checking the `ping' plugin stopped working after
2047 approximately 7.6 days.
2049 2006-04-21, Version 3.9.1
2050 * Build issues with Solaris and possible other architectures have been
2052 * Problems when building the `apache'-plugin without `libcurl' have
2054 * A bug in the `ping' plugin has been fixed. Sorry folks.
2056 2006-04-02, Version 3.9.0
2057 * A plugin to monitor the Apache webserver has been added.
2058 <http://httpd.apache.org/>
2059 * A plugin to collect statistics about virtual servers using VServer.
2060 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
2062 * A plugin for wireless LAN cards has been added. It monitors signal
2063 strength, link quality and noise ratio..
2064 * A plugin for Apple hardware sensors has been added.
2065 * An option to compile collectd with different `step' and `heartbeat'
2066 settings has been added. The size of RRAs is no longer static but
2067 calculated based on the settings for `step' and `width'.
2068 * The `ping' plugin can now be configured to use a certain TTL.
2069 * A plugin to monitor the hardware sensors of Apple computers has been
2071 * The plugins `cpu', `memory', `processes' and `traffic' have been
2072 ported to Mach/Darwin (Mac OS X).
2073 * The `log mode' has been contributed by Christophe Kalt. It writes
2074 the data into text files rather than RRD files.
2076 2006-04-09, Version 3.8.4
2077 * Applied patch by Vincent Stehlé which improves the disk-name
2078 resolution in the `hddtemp' plugin for Linux systems.
2080 2006-04-02, Version 3.8.3
2081 * Applied a patch by James Byers: The MySQL plugin was not working
2082 with MySQL 5.0.2 or later.
2084 2006-03-14, Version 3.8.2
2085 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
2086 the GNU libc, because it points to `/etc/fstab' rather than
2089 2006-03-13, Version 3.8.1
2090 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
2091 * Fixes in the debian `postinst' and `init.d' scripts.
2093 2006-03-09, Version 3.8.0
2094 * The `ping' plugin no longer uses `libping' but a self written
2095 library named `liboping'. With this library it's possible to ping
2096 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2098 2006-02-18, Version 3.7.2
2099 * A simple bug in the `battery' plugin has been fixed. It should now
2100 work with ACPI based batteries as well. Thanks to Sebastian for
2102 * Fixing a bug that prevented collectd to be built without librrd.
2103 Thanks to Werner Heuser for reporting it.
2105 2006-02-04, Version 3.7.1
2106 * The new network code has been improved to build with older versions
2108 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
2109 to Tommie Gannert for this patch.
2111 2006-01-30, Version 3.7.0
2112 * The `battery' plugin has been added. It collects information about
2114 * The MySQL plugin has been improved: It now writes two more RRD
2115 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
2116 * The `cpufreq' plugin now reads another file since the file it did
2117 read so far causes much overhead in the kernel. Also, you need root
2118 to read the old file, but not to read the new one.
2119 * The `hddtemp' plugin can now be configured to connect to another
2120 address and/or port than localhost.
2121 * The `df' plugin now prefers `statvfs' over `statfs'.
2122 * The network code has been rewritten. collectd now supports unicast
2123 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
2124 be set in the configfile.
2126 2006-01-24, Version 3.6.2
2127 * Due to a bug in the configfile handling collectd wouldn't start in
2128 client mode. This released fixes this.
2130 2006-01-20, Version 3.6.1
2131 * Due to a bug in `configure.in' all modules and the binary were
2132 linked against `libmysqlclient'. This issue is solved by this
2135 2006-01-17, Version 3.6.0
2136 * A config file has been added. This allows for loading only specific
2138 * A `df' plugin has been added.
2139 * A `mysql' plugin has been added.
2140 * The `ping' plugin doesn't entirely give up hope when a socket error
2141 occurred, but will back of and increase the intervals between tries.
2143 2006-01-21, Version 3.5.2
2144 * Fixed yet another bug in the signal handling.. Stupid typo..
2145 * Improved the ping plugin to not give up on socket errors (backport
2148 2005-12-18, Version 3.5.1
2149 * The PID-file is now deleted correctly when shutting down the daemon.
2150 * SIGINT and SIGTERM are now handled correctly.
2152 2005-12-16, Version 3.5.0 (Revision 326)
2153 * A bug in the `load' module under Solaris has been fixed.
2154 * The `users' module has been contributed by Sebastian Harl. It counts
2155 currently logged in users.
2156 * The CPU module now works under FreeBSD without the use of
2157 `libstatgrab', however SMP support is missing.
2158 * The default directories for the RRD files and the PID file now
2159 depend on the compile time setting of `localstatedir'.
2161 2005-11-15, Version 3.4.0 (Revision 236)
2162 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
2163 from gentoo's bugzilla for writing the patch.
2164 * The build dependency for librrd has been removed. Binaries built
2165 without librrd are client-only and will multicast their value as
2166 with the `-c' argument.
2167 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
2168 * The newly introduced `-f' switch prevents daemon initialization
2169 (forking, closing standard filehandles, etc.) Thanks to Alvaro
2170 Barcellos for this patch.
2172 2005-11-04, Version 3.3.0 (Revision 216)
2173 * New modules have been added:
2174 - `serial', for monitoring traffic on the serial interfaces
2175 - `nfs', for graphing NFS procedure calls
2176 - `tape', traffic from/to tape devices
2177 * The memory.rrd now accepts more than 4Gig of memory.
2179 2005-10-26, Version 3.2.0 (Revision 200)
2180 * Support for graphing the processes has been added (thanks to Lyonel
2182 * If reading from hddtemp fails collectd will increase the time
2183 between polls up to one day.
2184 * The init.d files have been improved.
2185 * Problems with the spec file have been fixed.
2187 2005-10-16, Version 3.1.0 (Revision 194)
2188 * Added the `setsid' syscall to the startup code.
2189 * Support for hddtemp has been added (thanks to Vincent Stehlé)
2191 2005-09-30, Version 3.0.0 (Revision 184)
2192 * The ability to send/receive data to/from the network (think
2193 multicast) has been added.
2194 * Modules have been split up into shared libraries can be loaded at
2195 runtime. The biggest advantage is that the core program doesn't need
2196 to be linked against an external library.
2197 * A patch by George Kargiotakis has been applied: It fixes the sensors
2198 behaviour then more than one sensor is being queried.
2200 2005-09-16, Version 2.1.0 (Revision 172)
2201 * A module for swap statistics has been added.
2203 2005-09-09, Version 2.0.0 (Revision 135)
2204 * Filenames can no longer be configured at program startup. The only
2205 options as of this version are the directory and ping hosts.
2206 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
2207 Soft-IRQ statistics are added to `System'.
2208 * Diskstats now collect read and write bytes, not sectors.
2209 * Ping statistics can now be collected for more than one host. There
2210 is no default any more: If no host is given no host will be pinged.
2211 * A self-written patch for libping has been applied so it builds
2214 2005-09-01, Version 1.8.1 (Revision 123)
2215 * Much improved configure-script: libraries and features may now be
2217 * More detailed warnings/error messages when RRD update fails.
2219 2005-08-29, Version 1.8.0:
2220 * Support for collecting disk statistics under Solaris.
2222 2005-08-25, Version 1.7.0:
2223 * Support for libstatgrab[1] for load, memory usage and network
2224 traffic. CPU- and disk-usage are not (yet) supported, since
2225 libstatgrab returns insufficient information. I will contact the
2227 * Improved the CPU-initialization code for Solaris. Apparently CPUs
2228 aren't necessarily counted linear which is now handled correctly.
2229 [1]: http://www.i-scream.org/libstatgrab/
2231 2005-08-21, Version 1.6.0:
2232 * Basic support for Solaris: System load and cpu-usage can be
2233 collected under Solaris, too. Other stats will follow later.
2234 * Many fixes in the autoconf-script
2235 * Collection/Museum scripts have been added under contrib/museum
2236 * collectd may now be started in unprivileged mode, though ping
2237 statistics will not work.
2239 2005-07-17, Version 1.5.1:
2240 * Diskstats-RRDs now use major/minor for naming. Some systems have
2241 weird strings as disk-names..
2243 2005-07-17, Version 1.5:
2244 * A new module, diskstats, has been added. It collects information
2245 about the disks and partitions.
2247 2005-07-11, Version 1.4.2:
2248 * The meminfo module has been changed to work with more platforms
2249 and/or kernel versions.
2251 2005-07-10, Version 1.4.1: Correct traffic stats
2252 * The traffic rrd-file is now created with DS-type `COUNTER' which I
2253 forgot to correct when I changed that module.
2255 2005-07-09, Version 1.4: More traffic stats
2256 * Traffic is now collected for all interfaces that can be found
2257 * Temperature-statistics are read from lm-sensors if available
2259 2005-07-08, Version 1.3: CPU stats
2260 * Collecting CPU statistics now
2262 2005-07-12, Version 1.2: Using syslog
2263 * collectd is now using the syslog facility to report errors, warnings
2265 * The default directory is now /var/db/collectd
2267 2005-07-10, Version 1.1: Minor changes
2268 * Nothing really useful to say ;)
2270 2005-07-09, Version 1.0: Initial Version
2271 * The following modules are provided:
