* collectd: Two bugs with the threshold checking have been fixed. The
first one prevented thresholds to be checked at all, the second one
caused wrong behavior with the persistency option. Thanks to Andrés
J. Díaz for fixing these problems.
* collectd: Handling of the `Include' configuration option has been
fixed.
* battery plugin: Don't complain about a missing directory every
interval.
* exec plugin: Allow executed programs to close STDERR. Thanks to
Thorsten von Eicken for reporting this problem.
* irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
Tomasz Pala for the patch.
* perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
the patch.
* memory plugin: Fix a potential problem under Solaris.

to Doug MacEachern for the patch.
2009-03-18, Version 4.6.2
* collectd: Some Solaris utility code has been improved.
* filter subsystem: Allow `Chains' without default targets.
* liboping: A patch to comply with strict aliasing rules has been
added.
* timediff match: Fix a typo: The match was registered with a wrong
name which prevented this match to be used as documented. Thanks to
Bruno Prémont for finding this problem.
* bind plugin: Fix collection of the cached RR sets. The number of RR
sets currently in the cache was collected as a counter value, which
is nonsense. Thanks to Bruno Prémont for implementing this.
* dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
primarily BSDs, don't take it well and crash.
* oracle plugin: Portability to 64 bit systems has been improved.
* postgresql plugin: The default configuration has been improved.
* rrdtool plugin: Fix a possible race condition: If the network plugin
is brought and dispatches a value before the rrdtool plugin is
initialized, the daemon may crash.
2009-02-22, Version 4.6.1
* collectd: Many documentation fixes.
* Collectd::Unixsock: Error handling has been improved.
* regex match: Don't link with the PCRE library.
* bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
for finding and fixing most of them.

faults. Thanks to Peter Holik for his patch.
2009-02-16, Version 4.6.0
* collectd: Added the `filter chain' infrastructure, which allows the
user to use `matches' and `targets' to control value processing.
* collectd: The new `-T' command line argument allows more in-depth
testing of a configuration. Thanks to Doug MacEachern for the patch.
* collectd-nagios: The Nagios integration command has been updated to
use libcollectdclient. The `percentage' aggregation function has
been added. Thanks to Fabian Linzberger for the patch.
* libcollectdclient: A library which abstracts communication with the
unixsock plugin for clients has been added.

* replace target: Replace parts of an identifier using regular
expressions.
* set target: Set (overwrite) entire parts of an identifier.
* bind plugin: This new plugin uses the new HTTP/XML interface to BIND
statistics, allowing very detailed name server statistics. Thanks to
Bruno Prémont for this plugin.
* cpu plugin: Report `interrupt' separately when using
sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
example for native OpenBSD support, has been added. Thanks to Simon
Kuhnle for the patch.
* csv plugin: Make it possible to write values to STDOUT instead of
files. This is meant for testing purposes mostly. The output written
to STDOUT is compatible with the exec plugin. Thanks to Doug
MacEachern for the patch.
* curl plugin: This new plugin can be used to read web pages and parse
them using the same mechanism that's used in the tail plugin.
* dbi plugin: This new plugin allows you to connect to a variety of
relational databases and use SQL to gather custom statistics from
it. It is similar to the already existing PostgreSQL plugin but uses
libdbi to communicate with the database(s).
* interface plugin: Use the ignorelist framework when selecting /
ignoring interfaces. This allows one to use regular expressions to
select interfaces, too.
* ipmi plugin: Handle temporary IPMI error conditions more gracefully.
Thanks to Bruno Prémont for this patch.
* memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
for the patch.
* mysql plugin: Allow connecting to a database via the UNIX domain
socket, too. Thanks to Mirko Buffoni for the patch.

code. This hopefully will help very large setups.
* openvpn plugin: This new plugin collects statistics provided by the
OpenVPN daemon. Thanks to Doug MacEachern for the patch.
* oracle plugin: This new plugin allows you to connect to an Oracle
database and use SQL to gather custom statistics from it. It is
similar to the already existing PostgreSQL plugin.
* perl plugin: Compatibility fixes for broken versions of Perl 5.10
have been added.
* perl plugin: Export the newly added plugin_write() to Perl plugins.
* perl plugin: Added support for `notification meta data'.
* perl plugin: Added support for the `filter chain' infrastructure by
allowing plugins to register `matches' and `targets'.
* postgresql plugin: The preferred configuration syntax has been
updated to be in line with the syntax used by the new dbi and oracle
plugins. The compatibility code for the old syntax is present.
Support for the new `Result' blocks and the interval parameter has
been added.
* processes plugin: Stacksize and virtual memory usage statistics have
been added. Portability fixes.
* rrdcached plugin: This new plugin uses the (still in development)
RRD accelerator daemon, rrdcached. This daemon works very similar to
the original rrdtool plugin of collectd, but adds some more nice
features.
* swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
added.
2009-05-09, Version 4.5.4
* Build system, various plugins: Many build fixes for FreeBSD,
OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
for many fixes and providing a build system for many platforms,
Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
providing an OpenBSD system.
* collectd: Fix a potential race condition when creating directories.

interval.
* dns plugin: Slight portability fixes.
* exec plugin: Allow executed programs to close STDERR. Thanks to
Thorsten von Eicken for reporting this problem.
* irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
Tomasz Pala for the patch.
* perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
the patch.

patch.
* ipmi plugin: Fix an off-by-one error which could cause segmentation
faults. Thanks to Peter Holik for his patch.
* tcpconns plugin: An endianness problem has been fixed in the *BSD
code. Thanks to "thated" for reporting this.
2009-01-02, Version 4.5.2
* build system: Check for `mysql.h' and `mysql/mysql.h', since the
file may be in both locations, especially when the database was
installed in a non-standard path. Thanks to Dusty Doris for
reporting this.
* build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
Solaris, in the configure script automatically.
* build system, tcpconns plugin: Check for `kvm_nlist' and
`kvm_openfiles' before enabling the plugin: Solaris provides a KVM
library with similar functions to the BSD variant, but doesn't
provide these necessary functions.
* collectd.conf(5): Various fixes and clarifications.
* collectd: Remove a GNUism (unnamed unions), thus improving
portability.
* collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
This solves portability problems, especially for Solaris.
* dns plugin: Fix a portability problem with NetBSD.
* filecount plugin: Fix an off-by-one error. This error may cause a
segmentation fault.
* network plugin: Fix the handling of `type' in the network protocol.
Due to a programming mistake, only 4 or 8 bytes would be copied to a
much larger buffer. This caused the `type' to be transferred much
more often than necessary. In some cases, e. g. the `cpu' and
`cpufreq' plugins being used at the same time, data may be corrupted
in those files. Thanks to Bruno Prémont for debugging and reporting
this issue.
* processes plugin: Fix a possible segmentation fault when specifying
invalid configuration options.
* unixsock plugin: Make sure the initialization function is run only
once. This resolves a file descriptor leak under systems which run
the initialization more than once, such as Solaris.
2008-10-16, Version 4.5.1
* build system: Change `--enable-<plugin>' to abort with an error if
dependencies are not met. Thanks to Bruno Prémont for the patch.
Also, the poisoning of various string functions has been restricted
to debug builds.
* collectd: Fix a memory leak in the global value cache. With every
*missing* value a couple of bytes would be leaked. Another memory
leak in the configuration handling code has been fixed. Thanks to
Niraj Tolia for reporting these issues.
* collectd: Fix an off-by-one error in the ignorelist functionality.
When using regular expressions, the last character would be missing,
possibly matching differently from what one would expect.
* collectdmon: Don't block SIGCHLD. This fixes a potential portability
problem.
* collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
Linzberger for reporting the bug.
* iptables plugin: Fix an off-by-one error. If a string was just one
character too long, it was truncated instead of reporting an error.
* network plugin: Fix a memory leak in the configuration handling
code. Thanks to Niraj Tolia for reporting this issue.
* perl plugin: Log an error message if bootstrapping `Collectd' fails.
* postgresql plugin: Don't reopen connection during reinitialization.
This fixes a bug under Solaris and potentially other platforms.
Missing calls to `PQclear' have been added, too. This fixes memory
leaks. Thanks to ``Admin'' for reporting these bugs.
* snmp plugin: Don't expect null-terminated strings from the Net-SNMP
library.
* tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
problems with some `libc's. Thanks to Matthias Lay for reporting the
bug.

they are in non-standard paths.
* build system: Portability fixes: Automatically define "_REENTRANT"
if the libc expects it.
* collectd: Error and warning messages have been improved.
* collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
using them.
* apache plugin: Allocate new memory when reading a webpage instead of
using a buffer of static size.
* exec plugin: Close (almost) all filedescriptors before exec(2)ing
the program.

means that you can configure threshold values for each data
instance. If this threshold is exceeded a notification will be
created.
* collectd: The new `FQDNLookup' option tells the daemon to use the
full qualified domain name as the hostname, not just the host part
es returned by `gethostname(2)'.
* collectd: Support for more than one `TypesDB' file has been added.
This is useful when one such file is included in a package but one
wants to add custom type definitions.
* collectd: The `Include' config option has been expanded to handle
entire directories and shell wildcards.

* ntpd plugin: The new `ReverseLookups' can be used to disable reverse
domain name lookups in this plugin.
* perl plugin: Many internal changes added support for handling multiple
threads making the plugin reasonably usable inside collectd. The API has
been extended to support notifications and export global variables to
Perl plugins; callbacks now have to be identified by name rather than a
pointer to a subroutine. The plugin is no longer experimental.
* uuid plugin: The new UUID plugin sets the hostname to an unique
identifier for this host. This is meant for setups where each client
may migrate to another physical host, possibly going through one or
more name changes in the process. Thanks to Richard Jones from
Red Hat's Emerging Technology group for this plugin.
* libvirt: The new libvirt plugin uses the `libvirt' library to query
CPU, disk and network statistics about guest systems on the same
physical server. Thanks to Richard Jones from Red Hat's Emerging
Technology group for this plugin.

and dispatching incoming packets. Versions prior to this may have
problems in high-load situations, where the socket receive buffers
overflows, resulting in gaps in the data.
+ Use `memcpy' when constructing/parsing a package to avoid
alignment problems on weird architectures, such as Sparc.
+ Translate doubles to/from the x86 byte representation to ensure
cross-platform compatibility.
* ping plugin: Correct the handling of the `TTL' setting.
* rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
* swap plugin: Reapply a patch for Solaris.
* tcpconns plugin: Portability improvements.

2007-12-28, Version 4.2.3
* sensors plugin: Updated the plugin to build and work with version 3
of the libsensors library.
2007-12-15, Version 4.2.2
* nginx plugin: Incorrect comparison of strings lead to a segfault
when using the plugin. Thanks to Saulius Grigaliunas for fixing
this.

incorrectly and basically always active. Thanks to Luke Heberling
for fixing this.
2007-11-08, Version 4.2.1
* tcpconns plugin: Don't complain about a missing file if IPv6 is not
enabled on the host.
* snmp plugin: Fix a memory leak.
2007-10-27, Version 4.2.0
* collectd: The new config option `Include' lets you include other
configfiles and thus split up your config into smaller parts. This
may be especially interesting for the snmp plugin to keep the data
definitions separate from the host definitions.
* ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
(number of connections, octets and packets for each service and
destination). Thanks to Sebastian Harl for this plugin.
* memcached plugin: The new `memcached' plugin connects to a memcached
daemon process and collects statistics of this distributed caching
system. Thanks to Antony Dovgal for contributing this plugin.
* nginx plugin: The new `nginx' plugin reads the status page of an
nginx daemon and saves the handled connections and requests.
* perl plugin: Many changes, including the added `EnableDebugger'
config option which lets you debug your Perl plugins more easily.
* rrdtool plugin: Use the thread-safe RRD-library if available. Try to
be more thread-safe otherwise by locking calls to the library.
* snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
correct the values returned by SNMP-agents. If a <data> block is
defined as `table' the instance is now optional. The sequence number
is used as the type-instance in this case. The new `InstancePrefix'
option allows to add arbitrary prefixes to the type-instance.
* tcpconns plugin: The new `tcpconns' plugin collects the number of
certain TCP connections and what state they're in. This can be used
to see how many connections your FTP server has to handle or how
many outgoing connections your mailserver has open.
2008-01-11, Version 4.1.6
* unixsock plugin: A bug in the unixsock plugin caused it not to set
the permission on the socket as documented in the manpage. Thanks to
Evgeny Chukreev for fixing this issue.

includes (i. e. Debian Sarge) have been fixed.
* snmp plugin: Fix a potential segfault when a host times out. Add
support for the `timeticks' type.
2007-09-12, Version 4.1.1
* Build system: The detection of `libnetlink' has been improved.
* collectd: The documentation has been fixed in numerous places.
* exec plugin: Setting the group under which to run a program has been
fixed.

fails.
* apcups plugin: Fix the `types' used to submit the values: They still
has an `apcups_' prefix which doesn't work anymore.
* rrdtool plugin: Create new RRD-files with the `begin' time set to
whatever the client thinks is `now'..
2007-09-01, Version 4.1.0
* Build system: The build system has been changed to automatically
disable all plugins, which are missing dependencies. The dependency
checking has been removed from the plugins themselves to remove
redundancy.
* Flexible interval: The interval of collected data is now sent along
with the data itself over the network, so that the interval-settings
of server and clients no longer needs to match.
* netlink plugin: The new `netlink' plugin connects to the Linux
kernel using a netlink socket and uses it to query information about
interfaces, qdiscs and classes.
* rrdtool plugin: The cache is now dumped to disk in an extra thread
to not block data collection.
* snmp plugin: The new `snmp' plugin can read values from SNMP enabled
network devices, such as switches, routers, thermometers, rack
monitoring servers, etc. The collectd-snmp(5) manpage documents this
plugin.
* unixsock plugin: Added the `LISTVAL' command.
* xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
of music played with xmms.
2007-09-28, Version 4.0.9
* apcups plugin: Fix reporting of the `load percent' data.
* wireless plugin: Correct the handling of cards returning signal and
noise quality as percentage.
* perl plugin: Fix a possible buffer overflow in get_module_name().
2007-09-12, Version 4.0.8
* collectd: The `sstrerror' function was improved to work correctly
with the broken GNU version of `strerror_r'.
* collectd: Write an error message to STDERR when loading of a plugin
fails.
* apcups plugin: Fix the `types' used to submit the values: They still
has an `apcups_' prefix which doesn't work anymore.
* rrdtool plugin: Create new RRD-files with the `begin' time set to
whatever the client thinks is `now'..
2007-08-26, Version 4.0.7
* documentation: Some typos have been fixed and some information has
been improved.
* build system: Many fixes for detecting libraries in unusual places,
such as on RedHat systems. The affected libraries are `libcurl',
`libmysql', and `libupsclient'.
* network plugin: Allow the `Port' option to be specified as a number
(i. e. without quotes).
* nut plugin: A fix allows linking the nut plugin against
libupsclient, version >= 2.2.0.
* processes plugin: Fix a potential segmentation fault.
2007-07-30, Version 4.0.6
* sensors plugin: Fix the ignorelist functionality: Only the `type
instance' was used to match against the list, but the documentation
told otherwise. This release fixes the code, so it complies with the
documentation.
* syslog plugin: Call `openlog' right when the plugin is loaded, so
configuration messages will end up in the logging facility.
* conrtib/fedora: The contributed specfile for Fedora has been
updated.
2007-07-05, Version 4.0.5
* Portability: More fixes for OpenBSD have been included.
2007-06-24, Version 4.0.4

2007-06-19, Version 4.0.3
* cpu plugin: Fix the Darwin / Mac OS X code.
* ping plugin: Use the return value of `getpid', not its address.
* csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
initialized correctly.
* configure: Added `--with-nan-emulation' to aid cross compilation.
2007-06-12, Version 4.0.2
* hddtemp and ntpd plugin: Corrected the parsing of port numbers when
they're given in numerically form.
2007-06-07, Version 4.0.1
* iptables plugin: A bug in the configuration routine has been fixed.
Setting a comment in the configfile will no longer cause a
segmentation fault.
2007-06-03, Version 4.0.0
* collectd: The plugin-infrastructure has been changed to allow for
more types of plugins, namely `write' and `log' plugins.
* collectd: The read-function has been changed to read many plugins in
parallel, using threads. Thus, plugins generally need to use
thread-safe functions from now on.
* collectd: The '-t' command line options allows to perform syntax tests
of the configuration file and exit immediately.
* csv plugin: The new `csv' plugin handles output to `comma separated
values'-files.
* rrdtool plugin: The new `rrdtool' plugin handles output to
RRD-files. Data can be cached to combine multiple updates into one
write to increase IO-performance.
* network plugin: The new `network' plugin handles IO via the network.
It implements a different, much more extensible protocol which can
combine many values in one packet, decreasing the number of UDP-
packets being sent. It can read from and send to the network and
with the appropriate configuration even forward packets to other
networks.
* unixsock plugin: The new `unixsock' plugin provides an interface to
communicate with the daemon while it is running. Right now the
commands `GETVAL' and `PUTVAL' are implemented, but more are to
come.
* perl plugin: The new `perl' plugin allows you to write extensions
for collectd in the scripting-language Perl.
* logfile plugin: The new `logfile' plugin writes logmessages to files
or STDOUT or STDERR.
* syslog plugin: The new `syslog' plugin sends logmessages to the
system's syslog daemon.

entropy currently being available to the system.
* exec plugin: The new `exec' plugin forks child processes and reads
back values provided by the forked processes.
* iptables plugin: The new `iptables' plugin reads counters from
iptables rules. Thanks to Sjoerd van der Berg for contributing this
plugin.
* irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
to Peter Holik for contributing this plugin.
* nut plugin: The new `nut' plugin connects the upsd of the `network
ups tools' and reads information about the connected UPS.
* apache plugin: Support for lighttpd's `BusyServers' (aka.
connections) field was added by Florent Monbillard.
* collectd-nagios: The new `collectd-nagios' binary queries values
from collectd, parses them and exits according to Nagios-standards.
* manpages: The manpages have been improved a lot.
2007-09-28, Version 3.11.7
* wireless plugin: Correct the handling of cards returning signal and
noise quality as percentage.
2007-08-31, Version 3.11.6
* processes plugin: Fix a potential segmentation fault.
2007-05-29, Version 3.11.5
* configure: Added `AC_SYS_LARGEFILE' for LFS.
* ntpd plugin: Fix a potential buffer overflow.
* processes plugin: Fix a bug when run under Linux 2.4. All processes
were accounted as `zombies'.
2007-04-10, Version 3.11.4
* dns plugin: Change the order of includes to make the plugin compile
under FreeBSD.
2007-03-30, Version 3.11.3
* configure: Have the configure-script define `HAVE_LIBKSTAT' instead
of the unused `COLLECT_KSTAT'.
2007-02-11, Version 3.11.2
* plugin: Catch NULL-pointer and try to fix them. Otherwise the
NULL-pointer may have been passed to `printf' which causes a
segfault with some libcs.
2007-02-10, Version 3.11.1
* df plugin: Some wrong defines have been fixed so the plugin works
under Solaris again.
* dns plugin: The usage of a struct has been fixed to work with
non-GNU libcs.
* processes plugin: Some missing defines have been added so the plugin
compiles cleanly under FreeBSD and presumably other UNIXes.
2006-12-22, Version 3.11.0
* collectd: The new command line option `-P' makes it easier for
distributors to change the location of PID-files.
* collectd: The daemon shuts down faster now which makes it easier to
write init.d-scripts for it.
* apache plugin: Increase the buffersize to 16k, because the 4k buffer
caused problems every now and then.
* df plugin: New config options allow to ignore certain mountpoints,
filesystem types or devices.
* dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
and interprets it. It collects traffic as well as qtype, opcode and
rcode counts.
* email plugin: Sebastian Harl has contributed this plugin which
counts received mails in categories (e. g. ham, spam, virus), spam
score (as given by SpamAssassin) and check types.
* mbmon plugin: Flavio Stanchina has contributed this plugin which
uses `mbmon' to gather information from sensors on the motherboard.
* processes plugin: Collect detailed statistics for configured
processes, that's process and thread count, CPU usage, resident
segment size and pagefaults.
* multimeter plugin: Peter Holik contributed a new plugin which
queries multimeters.
* sensors plugin: Lubos Stanek has put much effort into improving this
plugin, including `extended naming', collection of voltage values
and the possibility to ignore certain values.
2006-12-21, Version 3.10.4
* Max Kellermann has identified a bug in the server routine: When
opening a socket fails the daemon will (re)try opening the socket in
an endless loop, ultimately leading to a `EMFILE' error.
2006-11-04, Version 3.10.3
* Lubos Stanek has identified a bug in the ntpd-plugin: When the
ntpd's reply was sent in more than one packet, the buffer size was
calculated incorrectly, resulting in the reading of uninitialized or
freed memory.
2006-11-01, Version 3.10.2
* The sample config file has been improved.
* Errors in the manpages have been corrected.
* The ping-plugin now adds hosts during initialization, not during
startup. This speeds up startup when no network connectivity is
available. Also, the hosts are being added later when the network is
available.
* Improved BSD-support for the df-plugin.
* Fixed syntax errors in the swap-plugin for Mac OS X.
* Fix a wrong structure being passed to `getnameinfo' in the ntpd-
plugin.
* Don't disable the mysql-plugin if connecting to the database fails
during initialization. Instead, try again in increasing intervals.
2006-07-19, Version 3.10.1
* A bug in the apcups plugin was fixed: Is the plugin is loaded, but
the apcups cannot be reached, unconnected sockets will pile up and
eventually lead to `Too many open files' errors.
2006-07-09, Version 3.10.0
* The `disk' plugin has been ported to Darwin.
* The `battery' plugin should work on many Apple computers now.
* The `traffic' plugin can now ignore certain interfaces. Also,
statistics for sent/received packets and errors have been added.
* A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
to Anthony Gialluca for contributing this plugin and providing me
with a test environment :)
* A plugin for monitoring an NTP instance and the local clock drift
has been added.
2006-06-25, Version 3.9.4
* The Solaris code in the `swap' plugin has been changed to reflect
the numbers returned by `swap -s'. Thanks to Christophe Kalt for
working this out.
* The debugging system has been fixed to work with the Sun libc.
* When built without librrd the variable `operating_mode' could be
uninitialized. Thanks to David Elliot for reporting the bug.
2006-06-01, Version 3.9.3
* Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
operating systems also profit from the changes, but I wasn't able to
check that.
* Changed the build system to find the netinet-includes under FreeBSD
and therefore successfully build the `liboping' library there.
2006-05-09, Version 3.9.2
* Applied a patch to the `liboping' library. Due to a bug in the
sequence checking the `ping' plugin stopped working after
approximately 7.6 days.
2006-05-09, Version 3.8.5
* Applied a patch to the `liboping' library. Due to a bug in the
sequence checking the `ping' plugin stopped working after
approximately 7.6 days.
2006-04-21, Version 3.9.1
* Build issues with Solaris and possible other architectures have been
resolved.
* Problems when building the `apache'-plugin without `libcurl' have
been resolved.
* A bug in the `ping' plugin has been fixed. Sorry folks.
2006-04-02, Version 3.9.0
* A plugin to monitor the Apache webserver has been added.
<http://httpd.apache.org/>
* A plugin to collect statistics about virtual servers using VServer.
<http://linux-vserver.org/> Thanks to Sebastian Harl for writing
this plugin :)
* A plugin for wireless LAN cards has been added. It monitors signal
strength, link quality and noise ratio..
* A plugin for Apple hardware sensors has been added.
* An option to compile collectd with different `step' and `heartbeat'
settings has been added. The size of RRAs is no longer static but
calculated based on the settings for `step' and `width'.
* The `ping' plugin can now be configured to use a certain TTL.
* A plugin to monitor the hardware sensors of Apple computers has been
added.
* The plugins `cpu', `memory', `processes' and `traffic' have been
ported to Mach/Darwin (Mac OS X).
* The `log mode' has been contributed by Christophe Kalt. It writes
the data into text files rather than RRD files.
2006-04-09, Version 3.8.4
* Applied patch by Vincent Stehlé which improves the disk-name
resolution in the `hddtemp' plugin for Linux systems.
2006-04-02, Version 3.8.3
* Applied a patch by James Byers: The MySQL plugin was not working
with MySQL 5.0.2 or later.
2006-03-14, Version 3.8.2
* `utils_mount.c' has been changed to not use the `MNTTAB' defined by
the GNU libc, because it points to `/etc/fstab' rather than
`/etc/mtab'.
2006-03-13, Version 3.8.1
* Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
* Fixes in the debian `postinst' and `init.d' scripts.
2006-03-09, Version 3.8.0
* The `ping' plugin no longer uses `libping' but a self written
library named `liboping'. With this library it's possible to ping
multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2006-02-18, Version 3.7.2
* A simple bug in the `battery' plugin has been fixed. It should now
work with ACPI based batteries as well. Thanks to Sebastian for
fixing this.
* Fixing a bug that prevented collectd to be built without librrd.
Thanks to Werner Heuser for reporting it.
2006-02-04, Version 3.7.1
* The new network code has been improved to build with older versions
of glibc.
* Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
to Tommie Gannert for this patch.
2006-01-30, Version 3.7.0
* The `battery' plugin has been added. It collects information about
laptop batteries..
* The MySQL plugin has been improved: It now writes two more RRD
files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
* The `cpufreq' plugin now reads another file since the file it did
read so far causes much overhead in the kernel. Also, you need root
to read the old file, but not to read the new one.
* The `hddtemp' plugin can now be configured to connect to another
address and/or port than localhost.
* The `df' plugin now prefers `statvfs' over `statfs'.
* The network code has been rewritten. collectd now supports unicast
and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
be set in the configfile.
2006-01-24, Version 3.6.2
* Due to a bug in the configfile handling collectd wouldn't start in
client mode. This released fixes this.
2006-01-20, Version 3.6.1
* Due to a bug in `configure.in' all modules and the binary were
linked against `libmysqlclient'. This issue is solved by this
release.
2006-01-17, Version 3.6.0
* A config file has been added. This allows for loading only specific
plugins.
* A `df' plugin has been added.
* A `mysql' plugin has been added.
* The `ping' plugin doesn't entirely give up hope when a socket error
occurred, but will back of and increase the intervals between tries.
2006-01-21, Version 3.5.2
* Fixed yet another bug in the signal handling.. Stupid typo..
* Improved the ping plugin to not give up on socket errors (backport
from 3.6.0).
2005-12-18, Version 3.5.1
* The PID-file is now deleted correctly when shutting down the daemon.
* SIGINT and SIGTERM are now handled correctly.
2005-12-16, Version 3.5.0 (Revision 326)
* A bug in the `load' module under Solaris has been fixed.
* The `users' module has been contributed by Sebastian Harl. It counts
currently logged in users.
* The CPU module now works under FreeBSD without the use of
`libstatgrab', however SMP support is missing.
* The default directories for the RRD files and the PID file now
depend on the compile time setting of `localstatedir'.
2005-11-15, Version 3.4.0 (Revision 236)
* A PID-file is written to /var/run upon startup. Thanks to `Tommie'
from gentoo's bugzilla for writing the patch.
* The build dependency for librrd has been removed. Binaries built
without librrd are client-only and will multicast their value as
with the `-c' argument.
* A patch by Peter Holik adds a module for monitoring CPU frequencies.
* The newly introduced `-f' switch prevents daemon initialization
(forking, closing standard filehandles, etc.) Thanks to Alvaro
Barcellos for this patch.
2005-11-04, Version 3.3.0 (Revision 216)
* New modules have been added:
- `serial', for monitoring traffic on the serial interfaces
- `nfs', for graphing NFS procedure calls
- `tape', traffic from/to tape devices
* The memory.rrd now accepts more than 4Gig of memory.
2005-10-26, Version 3.2.0 (Revision 200)
* Support for graphing the processes has been added (thanks to Lyonel
Vincent)
* If reading from hddtemp fails collectd will increase the time
between polls up to one day.
* The init.d files have been improved.
* Problems with the spec file have been fixed.
2005-10-16, Version 3.1.0 (Revision 194)
* Added the `setsid' syscall to the startup code.
* Support for hddtemp has been added (thanks to Vincent Stehlé)
2005-09-30, Version 3.0.0 (Revision 184)
* The ability to send/receive data to/from the network (think
multicast) has been added.
* Modules have been split up into shared libraries can be loaded at
runtime. The biggest advantage is that the core program doesn't need
to be linked against an external library.
* A patch by George Kargiotakis has been applied: It fixes the sensors
behaviour then more than one sensor is being queried.
2005-09-16, Version 2.1.0 (Revision 172)
* A module for swap statistics has been added.
2005-09-09, Version 2.0.0 (Revision 135)
* Filenames can no longer be configured at program startup. The only
options as of this version are the directory and ping hosts.
* CPU statistics now include Wait-IO. If provided under Linux IRQ and
Soft-IRQ statistics are added to `System'.
* Diskstats now collect read and write bytes, not sectors.
* Ping statistics can now be collected for more than one host. There
is no default any more: If no host is given no host will be pinged.
* A self-written patch for libping has been applied so it builds
cleanly.
2005-09-01, Version 1.8.1 (Revision 123)
* Much improved configure-script: libraries and features may now be
disabled.
* More detailed warnings/error messages when RRD update fails.
2005-08-29, Version 1.8.0:
* Support for collecting disk statistics under Solaris.
2005-08-25, Version 1.7.0:
* Support for libstatgrab[1] for load, memory usage and network
traffic. CPU- and disk-usage are not (yet) supported, since
libstatgrab returns insufficient information. I will contact the
authors.
* Improved the CPU-initialization code for Solaris. Apparently CPUs
aren't necessarily counted linear which is now handled correctly.
[1]: http://www.i-scream.org/libstatgrab/
2005-08-21, Version 1.6.0:
* Basic support for Solaris: System load and cpu-usage can be
collected under Solaris, too. Other stats will follow later.
* Many fixes in the autoconf-script
* Collection/Museum scripts have been added under contrib/museum
* collectd may now be started in unprivileged mode, though ping
statistics will not work.
2005-07-17, Version 1.5.1:
* Diskstats-RRDs now use major/minor for naming. Some systems have
weird strings as disk-names..
2005-07-17, Version 1.5:
* A new module, diskstats, has been added. It collects information
about the disks and partitions.
2005-07-11, Version 1.4.2:
* The meminfo module has been changed to work with more platforms
and/or kernel versions.
2005-07-10, Version 1.4.1: Correct traffic stats
* The traffic rrd-file is now created with DS-type `COUNTER' which I
forgot to correct when I changed that module.
2005-07-09, Version 1.4: More traffic stats
* Traffic is now collected for all interfaces that can be found
* Temperature-statistics are read from lm-sensors if available
2005-07-08, Version 1.3: CPU stats
* Collecting CPU statistics now
2005-07-12, Version 1.2: Using syslog
* collectd is now using the syslog facility to report errors, warnings
and the like..
* The default directory is now /var/db/collectd
2005-07-10, Version 1.1: Minor changes
* Nothing really useful to say ;)
2005-07-09, Version 1.0: Initial Version
* The following modules are provided:
* Load average
* Ping time
