1 2006-11-04, Version 3.10.3
2 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
3 ntpd's reply was sent in more than one packet, the buffer size was
4 calculated incorrectly, resulting in the reading of uninitialized or
7 2006-11-01, Version 3.10.2
8 * The sample config file has been improved.
9 * Errors in the manpages have been corrected.
10 * The ping-plugin now adds hosts during initialization, not during
11 startup. This speeds up starup when no network connectivity is
12 available. Also, the hosts are being added later when the network is
14 * Improved BSD-support for the df-plugin.
15 * Fixed syntax errors in the swap-plugin for Mac OS X.
16 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
18 * Don't disable the mysql-plugin if connecting to the database fails
19 during initialization. Instead, try again in increasing intervals.
21 2006-07-19, Version 3.10.1
22 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
23 the apcups cannot be reached, unconnected sockets will pile up and
24 eventually lead to `Too many open files' errors.
26 2006-07-09, Version 3.10.0
27 * The `disk' plugin has been ported to Darwin.
28 * The `battery' plugin should work on many Apple computers now.

32 to Anthony Gialluca for contributing this plugin and providing me
33 with a test environment :)
34 * A plugin for moniroting an NTP instance and the local clock drift
37 2006-06-25, Version 3.9.4
38 * The Solaris code in the `swap' plugin has been changed to reflect
39 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
41 * The debugging system has been fixed to work with the Sun libc.
42 * When built without librrd the variable `operating_mode' could be
43 uninitialized. Thanks to David Elliot for reporting the bug.
45 2006-06-01, Version 3.9.3
46 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
47 operating systems also profit from the changes, but I wasn't able to
49 * Changed the build system to find the netinet-includes under FreeBSD
50 and therefore successfully build the `liboping' library there.
52 2006-05-09, Version 3.9.2
53 * Applied a patch to the `liboping' library. Due to a bug in the
54 sequence checking the `ping' plugin stopped working after
55 approximately 7.6 days.
57 2006-05-09, Version 3.8.5
58 * Applied a patch to the `liboping' library. Due to a bug in the
59 sequence checking the `ping' plugin stopped working after
60 approximately 7.6 days.
62 2006-04-21, Version 3.9.1
63 * Build issues with Solaris and possible other architectures have been
65 * Problems when building the `apache'-plugin without `libcurl' have

71 <http://httpd.apache.org/>
72 * A plugin to collect statistics about virtual servers using VServer.
73 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
75 * A plugin for wireless LAN cards has been added. It monitors signal
76 strength, link quality and noise ratio..
77 * A plugin for Apple hardware sensors has been added.
78 * An option to compile collectd with different `step' and `hearbeat'
79 settings has been added. The size of RRAs is no longer static but
80 calculated based on the settings for `step' and `width'.
81 * The `ping' plugin can now be configured to use a certain TTL.
82 * A plugin to monitor the hardware sensors of Apple computers has been
84 * The plugins `cpu', `memory', `processes' and `traffic' have been
85 ported to Mach/Darwin (Mac OS X).
86 * The `log mode' has been contributed by Christophe Kalt. It writes
87 the data into text files rather than RRD files.
89 2006-04-09, Version 3.8.4
90 * Applied patch by Vincent Stehlé which improves the disk-name
91 resolution in the `hddtemp' plugin for Linux systems.
93 2006-04-02, Version 3.8.3
94 * Applied a patch by James Byers: The MySQL plugin was not working
95 with MySQL 5.0.2 or later.
97 2006-03-14, Version 3.8.2
98 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
99 the GNU libc, because it points to `/etc/fstab' rather than
102 2006-03-13, Version 3.8.1
103 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
104 * Fixes in the debian `postinst' and `init.d' scripts.
106 2006-03-09, Version 3.8.0
107 * The `ping' plugin no longer uses `libping' but a self written
108 library named `liboping'. With this library it's possible to ping
109 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
111 2006-02-18, Version 3.7.2
112 * A simple bug in the `battery' plugin has been fixed. It should now
113 work with ACPI based batteries as well. Thankt to Sebastian for
115 * Fixing a bug that prevented collectd to be built without librrd.
116 Thanks to Werner Heuser for reporting it.
118 2006-02-04, Version 3.7.1
119 * The new network code has been improved to build with older versions

122 to Tommie Gannert for this patch.
124 2006-01-30, Version 3.7.0
125 * The `battery' plugin has been added. It collects information about
127 * The MySQL plugin has been improved: It now writes two more RRD
128 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
129 * The `cpufreq' plugin now reads another file since the file it did
130 read so far causes much overhead in the kernel. Also, you need root
131 to read the old file, but not to read the new one.
132 * The `hddtemp' plugin can now be configured to connect to another
133 address and/or port than localhost.
134 * The `df' plugin now prefers `statvfs' over `statfs'.
135 * The network code has been rewritten. collectd now supports unicast
136 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
137 be set in the configfile.
139 2006-01-24, Version 3.6.2
140 * Due to a bug in the configfile handling collectd wouldn't start in
141 client mode. This released fixes this.
143 2006-01-20, Version 3.6.1
144 * Due to a bug in `configure.in' all modules and the binary were
145 linked against `libmysqlclient'. This issue is solved by this
148 2006-01-17, Version 3.6.0
149 * A config file has been added. This allows for loading only specific
151 * A `df' plugin has been added.
152 * A `mysql' plugin has been added.
153 * The `ping' plugin doesn't entirely give up hope when a socket error
154 occured, but will back of and increase the intervals between tries.
156 2006-01-21, Version 3.5.2
157 * Fixed yet another bug in the signal handling.. Stupid typo..
158 * Improved the ping plugin to not give up on socket errors (backport

165 2005-12-16, Version 3.5.0 (Revision 326)
166 * A bug in the `load' module under Solaris has been fixed.
167 * The `users' module has been contributed by Sebastian Harl. It counts
168 currently logged in users.
169 * The CPU module now works under FreeBSD without the use of
170 `libstatgrab', however SMP support is missing.
171 * The default directories for the RRD files and the PID file now
172 depend on the compile time setting of `localstatedir'.
174 2005-11-15, Version 3.4.0 (Revision 236)
175 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
176 from gentoo's bugzilla for writing the patch.
177 * The build dependency for librrd has been removed. Binaries built
178 without librrd are client-only and will multicast their value as
179 with the `-c' argument.
180 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
181 * The newly introduced `-f' switch prevents daemon initialization
182 (forking, closing standard filehandles, etc.) Thanks to Alvaro
183 Barcellos for this patch.
185 2005-11-04, Version 3.3.0 (Revision 216)
186 * New modules have been added:
187 - `serial', for monitoring traffic on the serial interfaces
188 - `nfs', for graphing NFS procedure calls
189 - `tape', traffic from/to tape devices

202 * Support for hddtemp has been added (thanks to Vincent Stehlé)
204 2005-09-30, Version 3.0.0 (Revision 184)
205 * The ability to send/receive data to/from the network (think
206 multicast) has been added.
207 * Modules have been split up into shared libraries can be loaded at
208 runtime. The biggest advantage is that the core program doesn't need
209 to be linked against an external library.
210 * A patch by George Kargiotakis has been applied: It fixes the sensors
211 behaviour then more than one sensor is being queried.
213 2005-09-16, Version 2.1.0 (Revision 172)
214 * A module for swap statistics has been added.
216 2005-09-09, Version 2.0.0 (Revision 135)
217 * Filenames can no longer be configured at program startup. The only
218 options as of this version are the directory and ping hosts.
219 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
220 Soft-IRQ statistics are added to `System'.
221 * Diskstats now collect read and write bytes, not sectors.
222 * Ping statistics can now be collected for more than one host. There
223 is no default any more: If no host is given no host will be pinged.
224 * A self-written patch for libping has been applied so it builds
227 2005-09-01, Version 1.8.1 (Revision 123)
228 * Much improved configure-script: libraries and features may now be
230 * More detailed warnings/error messages when RRD update failes.
232 2005-08-29, Version 1.8.0:
233 * Support for collecting disk statistics under Solaris.
235 2005-08-25, Version 1.7.0:
236 * Support for libstatgrab[1] for load, memory usage and network
237 traffic. CPU- and disk-usage are not (yet) supported, since
238 libstatgrab returns insufficient information. I will contact the
240 * Improved the CPU-initialization code for Solaris. Apparently CPUs
241 aren't neccessarily counted linear which is now handled correctly.
242 [1]: http://www.i-scream.org/libstatgrab/
244 2005-08-21, Version 1.6.0:
245 * Basic support for Solaris: System load and cpu-usage can be

247 * Many fixes in the autoconf-script
248 * Collection/Museum scripts have been added unter contrib/museum
249 * collectd may now be started in unprivileged mode, though ping
250 statistics will not work.
252 2005-07-17, Version 1.5.1:
253 * Diskstats-RRDs now use major/minor for naming. Some systems have
254 weird strings as disk-names..
256 2005-07-17, Version 1.5:
257 * A new module, diskstats, has been added. It collects information
258 about the disks and partitions.

261 * The meminfo mofule has been changed to work with more platforms
262 and/or kernel versions.
264 2005-07-10, Version 1.4.1: Correct traffic stats
265 * The traffic rrd-file is now created with DS-type `COUNTER' which I
266 forgot to correct when I changed that module.
268 2005-07-09, Version 1.4: More traffic stats
269 * Traffic is now collected for all interfaces that can be found
270 * Temperature-statistics are read from lm-sensors if available
