1 2006-04-02, Version 3.9.0
2 * A plugin to monitor the Apache webserver has been added.
3 <http://httpd.apache.org/>
4 * A plugin to collect statistics about virtual servers using VServer.
5 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
7 * A plugin for wireless LAN cards has been added. It monitors signal
8 strength, link quality and noise ratio..
9 * An option to compile collectd with different `step' and `hearbeat'
10 settings has been added. The size of RRAs is no longer static but
11 calculated based on the settings for `step' and `width'.
12 * The `ping' plugin can now be configured to use a certain TTL.
13 * A plugin to monitor the hardware sensors of Apple computers has been
15 * The plugins `cpu', `memory', `processes' and `traffic' have been
16 ported to Mach/Darwin (Mac OS X).
18 2006-04-09, Version 3.8.4
19 * Applied patch by Vincent Stehlé which improves the disk-name
20 resolution in the `hddtemp' plugin for Linux systems.
22 2006-04-02, Version 3.8.3
23 * Applied a patch by James Byers: The MySQL plugin was not working
24 with MySQL 5.0.2 or later.
26 2006-03-14, Version 3.8.2
27 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
28 the GNU libc, because it points to `/etc/fstab' rather than
31 2006-03-13, Version 3.8.1
32 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
33 * Fixes in the debian `postinst' and `init.d' scripts.
35 2006-03-09, Version 3.8.0
36 * The `ping' plugin no longer uses `libping' but a self written
37 library named `liboping'. With this library it's possible to ping
38 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
40 2006-02-18, Version 3.7.2
41 * A simple bug in the `battery' plugin has been fixed. It should now
42 work with ACPI based batteries as well. Thankt to Sebastian for
44 * Fixing a bug that prevented collectd to be built without librrd.
45 Thanks to Werner Heuser for reporting it.
47 2006-02-04, Version 3.7.1
48 * The new network code has been improved to build with older versions
50 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
51 to Tommie Gannert for this patch.
53 2006-01-30, Version 3.7.0
54 * The `battery' plugin has been added. It collects information about
56 * The MySQL plugin has been improved: It now writes two more RRD
57 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
58 * The `cpufreq' plugin now reads another file since the file it did
59 read so far causes much overhead in the kernel. Also, you need root
60 to read the old file, but not to read the new one.
61 * The `hddtemp' plugin can now be configured to connect to another
62 address and/or port than localhost.
63 * The `df' plugin now prefers `statvfs' over `statfs'.
64 * The network code has been rewritten. collectd now supports unicast
65 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
66 be set in the configfile.
68 2006-01-24, Version 3.6.2
69 * Due to a bug in the configfile handling collectd wouldn't start in
70 client mode. This released fixes this.
72 2006-01-20, Version 3.6.1
73 * Due to a bug in `configure.in' all modules and the binary were
74 linked against `libmysqlclient'. This issue is solved by this
77 2006-01-17, Version 3.6.0
78 * A config file has been added. This allows for loading only specific
80 * A `df' plugin has been added.
81 * A `mysql' plugin has been added.
82 * The `ping' plugin doesn't entirely give up hope when a socket error
83 occured, but will back of and increase the intervals between tries.
85 2006-01-21, Version 3.5.2
86 * Fixed yet another bug in the signal handling.. Stupid typo..
87 * Improved the ping plugin to not give up on socket errors (backport
90 2005-12-18, Version 3.5.1
91 * The PID-file is now deleted correctly when shutting down the daemon.
92 * SIGINT and SIGTERM are now handled correctly.
94 2005-12-16, Version 3.5.0 (Revision 326)
95 * A bug in the `load' module under Solaris has been fixed.
96 * The `users' module has been contributed by Sebastian Harl. It counts
97 currently logged in users.
98 * The CPU module now works under FreeBSD without the use of
99 `libstatgrab', however SMP support is missing.
100 * The default directories for the RRD files and the PID file now
101 depend on the compile time setting of `localstatedir'.
103 2005-11-15, Version 3.4.0 (Revision 236)
104 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
105 from gentoo's bugzilla for writing the patch.
106 * The build dependency for librrd has been removed. Binaries built
107 without librrd are client-only and will multicast their value as
108 with the `-c' argument.
109 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
110 * The newly introduced `-f' switch prevents daemon initialization
111 (forking, closing standard filehandles, etc.) Thanks to Alvaro
112 Barcellos for this patch.
114 2005-11-04, Version 3.3.0 (Revision 216)
115 * New modules have been added:
116 - `serial', for monitoring traffic on the serial interfaces
117 - `nfs', for graphing NFS procedure calls
118 - `tape', traffic from/to tape devices
119 * The the memory.rrd now accepts more than 4Gig of memory.
121 2005-10-26, Version 3.2.0 (Revision 200)

124 * If reading from hddtemp failes collectd will increase the time
125 between polls up to one day.
126 * The init.d files have been improved.
127 * Problems with the spec file have been fixed.
129 2005-10-16, Version 3.1.0 (Revision 194)
130 * Added the `setsid' syscall to the startup code.
131 * Support for hddtemp has been added (thanks to Vincent Stehlé)
133 2005-09-30, Version 3.0.0 (Revision 184)
134 * The ability to send/receive data to/from the network (think
135 multicast) has been added.
136 * Modules have been split up into shared libraries can be loaded at
137 runtime. The biggest advantage is that the core program doesn't need
138 to be linked against an external library.
139 * A patch by George Kargiotakis has been applied: It fixes the sensors
140 behaviour then more than one sensor is being queried.
142 2005-09-16, Version 2.1.0 (Revision 172)
143 * A module for swap statistics has been added.
145 2005-09-09, Version 2.0.0 (Revision 135)
146 * Filenames can no longer be configured at program startup. The only
147 options as of this version are the directory and ping hosts.
148 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
149 Soft-IRQ statistics are added to `System'.
150 * Diskstats now collect read and write bytes, not sectors.
151 * Ping statistics can now be collected for more than one host. There
152 is no default any more: If no host is given no host will be pinged.
153 * A self-written patch for libping has been applied so it builds
156 2005-09-01, Version 1.8.1 (Revision 123)
157 * Much improved configure-script: libraries and features may now be
159 * More detailed warnings/error messages when RRD update failes.
161 2005-08-29, Version 1.8.0:
162 * Support for collecting disk statistics under Solaris.
164 2005-08-25, Version 1.7.0:
165 * Support for libstatgrab[1] for load, memory usage and network
166 traffic. CPU- and disk-usage are not (yet) supported, since
167 libstatgrab returns insufficient information. I will contact the
169 * Improved the CPU-initialization code for Solaris. Apparently CPUs
170 aren't neccessarily counted linear which is now handled correctly.
171 [1]: http://www.i-scream.org/libstatgrab/
173 2005-08-21, Version 1.6.0:
174 * Basic support for Solaris: System load and cpu-usage can be
175 collected unter Solaris, too. Other stats will follow later.
176 * Many fixes in the autoconf-script
177 * Collection/Museum scripts have been added unter contrib/museum
178 * collectd may now be started in unprivileged mode, though ping
179 statistics will not work.
181 2005-07-17, Version 1.5.1:
182 * Diskstats-RRDs now use major/minor for naming. Some systems have
183 weird strings as disk-names..
185 2005-07-17, Version 1.5:
186 * A new module, diskstats, has been added. It collects information
187 about the disks and partitions.
189 2005-07-11, Version 1.4.2:
190 * The meminfo mofule has been changed to work with more platforms
191 and/or kernel versions.
193 2005-07-10, Version 1.4.1: Correct traffic stats
194 * The traffic rrd-file is now created with DS-type `COUNTER' which I
195 forgot to correct when I changed that module.
197 2005-07-09, Version 1.4: More traffic stats
198 * Traffic is now collected for all interfaces that can be found
199 * Temperature-statistics are read from lm-sensors if available
201 2005-07-08, Version 1.3: CPU stats
202 * Collecting CPU statistics now
204 2004-07-12, Version 1.2: Using syslog
205 * collectd is now using the syslog facility to report errors, warnings
207 * The default directory is now /var/db/collectd
209 2004-07-10, Version 1.1: Minor changes
210 * Nothing really usefull to say ;)
212 2004-07-09, Version 1.0: Initial Version
213 * The following modules are provided:
