1 * The `disk' plugin has been ported to Darwin.
2 * The `battery' plugin should work on many Apple computers now.
4 2006-04-02, Version 3.9.0
5 * A plugin to monitor the Apache webserver has been added.
6 <http://httpd.apache.org/>
7 * A plugin to collect statistics about virtual servers using VServer.
8 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
10 * A plugin for wireless LAN cards has been added. It monitors signal
11 strength, link quality and noise ratio..
12 * An option to compile collectd with different `step' and `hearbeat'
13 settings has been added. The size of RRAs is no longer static but
14 calculated based on the settings for `step' and `width'.
15 * The `ping' plugin can now be configured to use a certain TTL.
16 * A plugin to monitor the hardware sensors of Apple computers has been
18 * The plugins `cpu', `memory', `processes' and `traffic' have been
19 ported to Mach/Darwin (Mac OS X).
20 * The `log mode' has been contributed by Christophe Kalt. It writes
21 the data into text files rather than RRD files.
23 2006-04-09, Version 3.8.4
24 * Applied patch by Vincent Stehlé which improves the disk-name
25 resolution in the `hddtemp' plugin for Linux systems.
27 2006-04-02, Version 3.8.3
28 * Applied a patch by James Byers: The MySQL plugin was not working
29 with MySQL 5.0.2 or later.
31 2006-03-14, Version 3.8.2
32 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
33 the GNU libc, because it points to `/etc/fstab' rather than
36 2006-03-13, Version 3.8.1
37 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
38 * Fixes in the debian `postinst' and `init.d' scripts.
40 2006-03-09, Version 3.8.0
41 * The `ping' plugin no longer uses `libping' but a self written
42 library named `liboping'. With this library it's possible to ping
43 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
45 2006-02-18, Version 3.7.2
46 * A simple bug in the `battery' plugin has been fixed. It should now
47 work with ACPI based batteries as well. Thankt to Sebastian for
49 * Fixing a bug that prevented collectd to be built without librrd.
50 Thanks to Werner Heuser for reporting it.
52 2006-02-04, Version 3.7.1
53 * The new network code has been improved to build with older versions
55 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
56 to Tommie Gannert for this patch.
58 2006-01-30, Version 3.7.0
59 * The `battery' plugin has been added. It collects information about
61 * The MySQL plugin has been improved: It now writes two more RRD
62 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
63 * The `cpufreq' plugin now reads another file since the file it did
64 read so far causes much overhead in the kernel. Also, you need root
65 to read the old file, but not to read the new one.
66 * The `hddtemp' plugin can now be configured to connect to another
67 address and/or port than localhost.
68 * The `df' plugin now prefers `statvfs' over `statfs'.
69 * The network code has been rewritten. collectd now supports unicast
70 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
71 be set in the configfile.
73 2006-01-24, Version 3.6.2
74 * Due to a bug in the configfile handling collectd wouldn't start in
75 client mode. This released fixes this.
77 2006-01-20, Version 3.6.1
78 * Due to a bug in `configure.in' all modules and the binary were
79 linked against `libmysqlclient'. This issue is solved by this
82 2006-01-17, Version 3.6.0
83 * A config file has been added. This allows for loading only specific
85 * A `df' plugin has been added.
86 * A `mysql' plugin has been added.
87 * The `ping' plugin doesn't entirely give up hope when a socket error
88 occured, but will back of and increase the intervals between tries.
90 2006-01-21, Version 3.5.2
91 * Fixed yet another bug in the signal handling.. Stupid typo..
92 * Improved the ping plugin to not give up on socket errors (backport
95 2005-12-18, Version 3.5.1
96 * The PID-file is now deleted correctly when shutting down the daemon.

99 2005-12-16, Version 3.5.0 (Revision 326)
100 * A bug in the `load' module under Solaris has been fixed.
101 * The `users' module has been contributed by Sebastian Harl. It counts
102 currently logged in users.
103 * The CPU module now works under FreeBSD without the use of
104 `libstatgrab', however SMP support is missing.
105 * The default directories for the RRD files and the PID file now
106 depend on the compile time setting of `localstatedir'.
108 2005-11-15, Version 3.4.0 (Revision 236)
109 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
110 from gentoo's bugzilla for writing the patch.
111 * The build dependency for librrd has been removed. Binaries built
112 without librrd are client-only and will multicast their value as
113 with the `-c' argument.
114 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
115 * The newly introduced `-f' switch prevents daemon initialization
116 (forking, closing standard filehandles, etc.) Thanks to Alvaro
117 Barcellos for this patch.
119 2005-11-04, Version 3.3.0 (Revision 216)
120 * New modules have been added:
121 - `serial', for monitoring traffic on the serial interfaces
122 - `nfs', for graphing NFS procedure calls
123 - `tape', traffic from/to tape devices
124 * The the memory.rrd now accepts more than 4Gig of memory.

132 * Problems with the spec file have been fixed.
134 2005-10-16, Version 3.1.0 (Revision 194)
135 * Added the `setsid' syscall to the startup code.
136 * Support for hddtemp has been added (thanks to Vincent Stehlé)
138 2005-09-30, Version 3.0.0 (Revision 184)
139 * The ability to send/receive data to/from the network (think
140 multicast) has been added.
141 * Modules have been split up into shared libraries can be loaded at
142 runtime. The biggest advantage is that the core program doesn't need
143 to be linked against an external library.
144 * A patch by George Kargiotakis has been applied: It fixes the sensors
145 behaviour then more than one sensor is being queried.
147 2005-09-16, Version 2.1.0 (Revision 172)
148 * A module for swap statistics has been added.
150 2005-09-09, Version 2.0.0 (Revision 135)
151 * Filenames can no longer be configured at program startup. The only
152 options as of this version are the directory and ping hosts.
153 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
154 Soft-IRQ statistics are added to `System'.
155 * Diskstats now collect read and write bytes, not sectors.
156 * Ping statistics can now be collected for more than one host. There
157 is no default any more: If no host is given no host will be pinged.
158 * A self-written patch for libping has been applied so it builds
161 2005-09-01, Version 1.8.1 (Revision 123)
162 * Much improved configure-script: libraries and features may now be
164 * More detailed warnings/error messages when RRD update failes.
166 2005-08-29, Version 1.8.0:
167 * Support for collecting disk statistics under Solaris.
169 2005-08-25, Version 1.7.0:
170 * Support for libstatgrab[1] for load, memory usage and network
171 traffic. CPU- and disk-usage are not (yet) supported, since
172 libstatgrab returns insufficient information. I will contact the
174 * Improved the CPU-initialization code for Solaris. Apparently CPUs
175 aren't neccessarily counted linear which is now handled correctly.
176 [1]: http://www.i-scream.org/libstatgrab/
178 2005-08-21, Version 1.6.0:
179 * Basic support for Solaris: System load and cpu-usage can be
180 collected unter Solaris, too. Other stats will follow later.
181 * Many fixes in the autoconf-script
182 * Collection/Museum scripts have been added unter contrib/museum
183 * collectd may now be started in unprivileged mode, though ping
184 statistics will not work.
186 2005-07-17, Version 1.5.1:
187 * Diskstats-RRDs now use major/minor for naming. Some systems have
188 weird strings as disk-names..
190 2005-07-17, Version 1.5:
191 * A new module, diskstats, has been added. It collects information
192 about the disks and partitions.
194 2005-07-11, Version 1.4.2:
195 * The meminfo mofule has been changed to work with more platforms
196 and/or kernel versions.
198 2005-07-10, Version 1.4.1: Correct traffic stats
199 * The traffic rrd-file is now created with DS-type `COUNTER' which I
200 forgot to correct when I changed that module.
202 2005-07-09, Version 1.4: More traffic stats
203 * Traffic is now collected for all interfaces that can be found
204 * Temperature-statistics are read from lm-sensors if available
206 2005-07-08, Version 1.3: CPU stats
