1 2006-04-21, Version 3.9.1
2 * Build issues with Solaris and possible other architectures have been
4 * Problems when building the `apache'-plugin without `libcurl' have
7 2006-04-15, Version 3.9.0
8 * A plugin to monitor the Apache webserver has been added.
9 <http://httpd.apache.org/>
10 * A plugin to collect statistics about virtual servers using VServer.
11 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
13 * A plugin for wireless LAN cards has been added. It monitors signal
14 strength, link quality and noise ratio..
15 * A plugin for Apple hardware sensors has been added.
16 * An option to compile collectd with different `step' and `hearbeat'
17 settings has been added. The size of RRAs is no longer static but
18 calculated based on the settings for `step' and `width'.
19 * The `ping' plugin can now be configured to use a certain TTL.
20 * A plugin to monitor the hardware sensors of Apple computers has been
22 * The plugins `cpu', `memory', `processes' and `traffic' have been
23 ported to Mach/Darwin (Mac OS X).
24 * The `log mode' has been contributed by Christophe Kalt. It writes
25 the data into text files rather than RRD files.
27 2006-04-09, Version 3.8.4
28 * Applied patch by Vincent Stehlé which improves the disk-name
29 resolution in the `hddtemp' plugin for Linux systems.
31 2006-04-02, Version 3.8.3
32 * Applied a patch by James Byers: The MySQL plugin was not working
33 with MySQL 5.0.2 or later.
35 2006-03-14, Version 3.8.2
36 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
37 the GNU libc, because it points to `/etc/fstab' rather than
40 2006-03-13, Version 3.8.1
41 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
42 * Fixes in the debian `postinst' and `init.d' scripts.
44 2006-03-09, Version 3.8.0
45 * The `ping' plugin no longer uses `libping' but a self written
46 library named `liboping'. With this library it's possible to ping
47 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
49 2006-02-18, Version 3.7.2
50 * A simple bug in the `battery' plugin has been fixed. It should now
51 work with ACPI based batteries as well. Thankt to Sebastian for
53 * Fixing a bug that prevented collectd to be built without librrd.
54 Thanks to Werner Heuser for reporting it.
56 2006-02-04, Version 3.7.1
57 * The new network code has been improved to build with older versions
59 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
60 to Tommie Gannert for this patch.
62 2006-01-30, Version 3.7.0
63 * The `battery' plugin has been added. It collects information about
65 * The MySQL plugin has been improved: It now writes two more RRD
66 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
67 * The `cpufreq' plugin now reads another file since the file it did
68 read so far causes much overhead in the kernel. Also, you need root
69 to read the old file, but not to read the new one.
70 * The `hddtemp' plugin can now be configured to connect to another
71 address and/or port than localhost.
72 * The `df' plugin now prefers `statvfs' over `statfs'.
73 * The network code has been rewritten. collectd now supports unicast
74 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
75 be set in the configfile.
77 2006-01-24, Version 3.6.2
78 * Due to a bug in the configfile handling collectd wouldn't start in
79 client mode. This released fixes this.
81 2006-01-20, Version 3.6.1
82 * Due to a bug in `configure.in' all modules and the binary were
83 linked against `libmysqlclient'. This issue is solved by this
86 2006-01-17, Version 3.6.0
87 * A config file has been added. This allows for loading only specific
89 * A `df' plugin has been added.
90 * A `mysql' plugin has been added.
91 * The `ping' plugin doesn't entirely give up hope when a socket error
92 occured, but will back of and increase the intervals between tries.
94 2006-01-21, Version 3.5.2
95 * Fixed yet another bug in the signal handling.. Stupid typo..
96 * Improved the ping plugin to not give up on socket errors (backport
99 2005-12-18, Version 3.5.1
100 * The PID-file is now deleted correctly when shutting down the daemon.
101 * SIGINT and SIGTERM are now handled correctly.
103 2005-12-16, Version 3.5.0 (Revision 326)
104 * A bug in the `load' module under Solaris has been fixed.
105 * The `users' module has been contributed by Sebastian Harl. It counts
106 currently logged in users.
107 * The CPU module now works under FreeBSD without the use of
108 `libstatgrab', however SMP support is missing.
109 * The default directories for the RRD files and the PID file now
110 depend on the compile time setting of `localstatedir'.
112 2005-11-15, Version 3.4.0 (Revision 236)
113 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
114 from gentoo's bugzilla for writing the patch.
115 * The build dependency for librrd has been removed. Binaries built
116 without librrd are client-only and will multicast their value as
117 with the `-c' argument.
118 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
119 * The newly introduced `-f' switch prevents daemon initialization
120 (forking, closing standard filehandles, etc.) Thanks to Alvaro
121 Barcellos for this patch.
123 2005-11-04, Version 3.3.0 (Revision 216)
124 * New modules have been added:
125 - `serial', for monitoring traffic on the serial interfaces
126 - `nfs', for graphing NFS procedure calls
127 - `tape', traffic from/to tape devices
128 * The the memory.rrd now accepts more than 4Gig of memory.
130 2005-10-26, Version 3.2.0 (Revision 200)
131 * Support for graphing the processes has been added (thanks to Lyonel
133 * If reading from hddtemp failes collectd will increase the time
134 between polls up to one day.
135 * The init.d files have been improved.
136 * Problems with the spec file have been fixed.
138 2005-10-16, Version 3.1.0 (Revision 194)
139 * Added the `setsid' syscall to the startup code.
140 * Support for hddtemp has been added (thanks to Vincent Stehlé)
142 2005-09-30, Version 3.0.0 (Revision 184)
143 * The ability to send/receive data to/from the network (think
144 multicast) has been added.
145 * Modules have been split up into shared libraries can be loaded at
146 runtime. The biggest advantage is that the core program doesn't need
147 to be linked against an external library.
148 * A patch by George Kargiotakis has been applied: It fixes the sensors
149 behaviour then more than one sensor is being queried.
151 2005-09-16, Version 2.1.0 (Revision 172)
152 * A module for swap statistics has been added.
154 2005-09-09, Version 2.0.0 (Revision 135)
155 * Filenames can no longer be configured at program startup. The only
156 options as of this version are the directory and ping hosts.
157 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
158 Soft-IRQ statistics are added to `System'.
159 * Diskstats now collect read and write bytes, not sectors.
160 * Ping statistics can now be collected for more than one host. There
161 is no default any more: If no host is given no host will be pinged.
162 * A self-written patch for libping has been applied so it builds
165 2005-09-01, Version 1.8.1 (Revision 123)
166 * Much improved configure-script: libraries and features may now be
168 * More detailed warnings/error messages when RRD update failes.
170 2005-08-29, Version 1.8.0:
171 * Support for collecting disk statistics under Solaris.
173 2005-08-25, Version 1.7.0:
174 * Support for libstatgrab[1] for load, memory usage and network
175 traffic. CPU- and disk-usage are not (yet) supported, since
176 libstatgrab returns insufficient information. I will contact the
178 * Improved the CPU-initialization code for Solaris. Apparently CPUs
179 aren't neccessarily counted linear which is now handled correctly.
180 [1]: http://www.i-scream.org/libstatgrab/
182 2005-08-21, Version 1.6.0:
183 * Basic support for Solaris: System load and cpu-usage can be
184 collected unter Solaris, too. Other stats will follow later.
185 * Many fixes in the autoconf-script
186 * Collection/Museum scripts have been added unter contrib/museum
187 * collectd may now be started in unprivileged mode, though ping
188 statistics will not work.
190 2005-07-17, Version 1.5.1:
191 * Diskstats-RRDs now use major/minor for naming. Some systems have
192 weird strings as disk-names..
194 2005-07-17, Version 1.5:
195 * A new module, diskstats, has been added. It collects information
196 about the disks and partitions.
198 2005-07-11, Version 1.4.2:
199 * The meminfo mofule has been changed to work with more platforms
200 and/or kernel versions.
202 2005-07-10, Version 1.4.1: Correct traffic stats
203 * The traffic rrd-file is now created with DS-type `COUNTER' which I
204 forgot to correct when I changed that module.
206 2005-07-09, Version 1.4: More traffic stats
207 * Traffic is now collected for all interfaces that can be found
208 * Temperature-statistics are read from lm-sensors if available
210 2005-07-08, Version 1.3: CPU stats
211 * Collecting CPU statistics now
213 2004-07-12, Version 1.2: Using syslog
214 * collectd is now using the syslog facility to report errors, warnings
216 * The default directory is now /var/db/collectd
