12 2006-06-25, Version 3.9.4
13 * The Solaris code in the `swap' plugin has been changed to reflect
14 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
16 * The debugging system has been fixed to work with the Sun libc.
17 * When built without librrd the variable `operating_mode' could be
18 uninitialized. Thanks to David Elliot for reporting the bug.
20 2006-06-01, Version 3.9.3
21 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
22 operating systems also profit from the changes, but I wasn't able to
24 * Changed the build system to find the netinet-includes under FreeBSD
25 and therefore successfully build the `liboping' library there.
27 2006-05-09, Version 3.9.2
28 * Applied a patch to the `liboping' library. Due to a bug in the
29 sequence checking the `ping' plugin stopped working after
30 approximately 7.6 days.
32 2006-05-09, Version 3.8.5
33 * Applied a patch to the `liboping' library. Due to a bug in the
34 sequence checking the `ping' plugin stopped working after

51 strength, link quality and noise ratio..
52 * A plugin for Apple hardware sensors has been added.
53 * An option to compile collectd with different `step' and `hearbeat'
54 settings has been added. The size of RRAs is no longer static but
55 calculated based on the settings for `step' and `width'.
56 * The `ping' plugin can now be configured to use a certain TTL.
57 * A plugin to monitor the hardware sensors of Apple computers has been
59 * The plugins `cpu', `memory', `processes' and `traffic' have been
60 ported to Mach/Darwin (Mac OS X).
61 * The `log mode' has been contributed by Christophe Kalt. It writes
62 the data into text files rather than RRD files.
64 2006-04-09, Version 3.8.4
65 * Applied patch by Vincent Stehlé which improves the disk-name
66 resolution in the `hddtemp' plugin for Linux systems.
68 2006-04-02, Version 3.8.3

72 2006-03-14, Version 3.8.2
73 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
74 the GNU libc, because it points to `/etc/fstab' rather than
77 2006-03-13, Version 3.8.1
78 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
79 * Fixes in the debian `postinst' and `init.d' scripts.
81 2006-03-09, Version 3.8.0
82 * The `ping' plugin no longer uses `libping' but a self written
83 library named `liboping'. With this library it's possible to ping
84 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
86 2006-02-18, Version 3.7.2
87 * A simple bug in the `battery' plugin has been fixed. It should now
88 work with ACPI based batteries as well. Thankt to Sebastian for
90 * Fixing a bug that prevented collectd to be built without librrd.
91 Thanks to Werner Heuser for reporting it.
93 2006-02-04, Version 3.7.1
94 * The new network code has been improved to build with older versions

97 to Tommie Gannert for this patch.
99 2006-01-30, Version 3.7.0
100 * The `battery' plugin has been added. It collects information about
102 * The MySQL plugin has been improved: It now writes two more RRD
103 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
104 * The `cpufreq' plugin now reads another file since the file it did
105 read so far causes much overhead in the kernel. Also, you need root
106 to read the old file, but not to read the new one.
107 * The `hddtemp' plugin can now be configured to connect to another
108 address and/or port than localhost.
109 * The `df' plugin now prefers `statvfs' over `statfs'.
110 * The network code has been rewritten. collectd now supports unicast
111 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
112 be set in the configfile.
114 2006-01-24, Version 3.6.2
115 * Due to a bug in the configfile handling collectd wouldn't start in
116 client mode. This released fixes this.
118 2006-01-20, Version 3.6.1
119 * Due to a bug in `configure.in' all modules and the binary were
120 linked against `libmysqlclient'. This issue is solved by this
123 2006-01-17, Version 3.6.0
124 * A config file has been added. This allows for loading only specific
126 * A `df' plugin has been added.
127 * A `mysql' plugin has been added.
128 * The `ping' plugin doesn't entirely give up hope when a socket error
129 occured, but will back of and increase the intervals between tries.
131 2006-01-21, Version 3.5.2
132 * Fixed yet another bug in the signal handling.. Stupid typo..
133 * Improved the ping plugin to not give up on socket errors (backport

140 2005-12-16, Version 3.5.0 (Revision 326)
141 * A bug in the `load' module under Solaris has been fixed.
142 * The `users' module has been contributed by Sebastian Harl. It counts
143 currently logged in users.
144 * The CPU module now works under FreeBSD without the use of
145 `libstatgrab', however SMP support is missing.
146 * The default directories for the RRD files and the PID file now
147 depend on the compile time setting of `localstatedir'.
149 2005-11-15, Version 3.4.0 (Revision 236)
150 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
151 from gentoo's bugzilla for writing the patch.
152 * The build dependency for librrd has been removed. Binaries built
153 without librrd are client-only and will multicast their value as
154 with the `-c' argument.
155 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
156 * The newly introduced `-f' switch prevents daemon initialization
157 (forking, closing standard filehandles, etc.) Thanks to Alvaro
158 Barcellos for this patch.
160 2005-11-04, Version 3.3.0 (Revision 216)
161 * New modules have been added:
162 - `serial', for monitoring traffic on the serial interfaces
163 - `nfs', for graphing NFS procedure calls
164 - `tape', traffic from/to tape devices

177 * Support for hddtemp has been added (thanks to Vincent Stehlé)
179 2005-09-30, Version 3.0.0 (Revision 184)
180 * The ability to send/receive data to/from the network (think
181 multicast) has been added.
182 * Modules have been split up into shared libraries can be loaded at
183 runtime. The biggest advantage is that the core program doesn't need
184 to be linked against an external library.
185 * A patch by George Kargiotakis has been applied: It fixes the sensors
186 behaviour then more than one sensor is being queried.
188 2005-09-16, Version 2.1.0 (Revision 172)
189 * A module for swap statistics has been added.
191 2005-09-09, Version 2.0.0 (Revision 135)
192 * Filenames can no longer be configured at program startup. The only
193 options as of this version are the directory and ping hosts.
194 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
195 Soft-IRQ statistics are added to `System'.
196 * Diskstats now collect read and write bytes, not sectors.
197 * Ping statistics can now be collected for more than one host. There
198 is no default any more: If no host is given no host will be pinged.
199 * A self-written patch for libping has been applied so it builds
202 2005-09-01, Version 1.8.1 (Revision 123)
203 * Much improved configure-script: libraries and features may now be
205 * More detailed warnings/error messages when RRD update failes.
207 2005-08-29, Version 1.8.0:
208 * Support for collecting disk statistics under Solaris.
210 2005-08-25, Version 1.7.0:
211 * Support for libstatgrab[1] for load, memory usage and network
212 traffic. CPU- and disk-usage are not (yet) supported, since
213 libstatgrab returns insufficient information. I will contact the
215 * Improved the CPU-initialization code for Solaris. Apparently CPUs
216 aren't neccessarily counted linear which is now handled correctly.
217 [1]: http://www.i-scream.org/libstatgrab/
219 2005-08-21, Version 1.6.0:
220 * Basic support for Solaris: System load and cpu-usage can be
221 collected unter Solaris, too. Other stats will follow later.
222 * Many fixes in the autoconf-script
223 * Collection/Museum scripts have been added unter contrib/museum
224 * collectd may now be started in unprivileged mode, though ping
225 statistics will not work.
227 2005-07-17, Version 1.5.1:
228 * Diskstats-RRDs now use major/minor for naming. Some systems have
229 weird strings as disk-names..

236 * The meminfo mofule has been changed to work with more platforms
237 and/or kernel versions.
239 2005-07-10, Version 1.4.1: Correct traffic stats
240 * The traffic rrd-file is now created with DS-type `COUNTER' which I
241 forgot to correct when I changed that module.
