- cpufreq
CPU frequency (For laptops with speed step or a similar technology)
+ - dbi
+ Executes SQL statements on various databases and interprets the returned
+ data.
+
- df
Mountpoint usage (Basically the values `df(1)' delivers)
Iptables' counters: Number of bytes that were matched by a certain
iptables rule.
+ - ipmi
+ IPMI (Intelligent Platform Management Interface) sensors information.
+
- ipvs
IPVS connection statistics (number of connections, octets and packets
for each service and destination).
PostgreSQL database statistics: active server connections, transaction
numbers, block IO, table row manipulations.
+ - powerdns
+ PowerDNS name server statistics.
+
- processes
Process counts: Number of running, sleeping, zombie, ... processes.
+ - rrdcached
+ RRDtool caching daemon (RRDcacheD) statistics.
+
- sensors
System sensors, accessed using lm_sensors: Voltages, temperatures and
fan rotation speeds.
- tcpconns
Number of TCP connections to specific local and remote ports.
+ - teamspeak2
+ TeamSpeak2 server statistics.
+
+ - thermal
+ Linux ACPI thermal zone information.
+
- users
Users currently logged in.
you can easily do weird stuff with the plugins we didn't dare think of
;) See collectd-perl(5).
+ - rrdcached
+ Output to round-robin-database (RRD) files using the RRDtool caching
+ daemon (RRDcacheD) - see rrdcached(1). That daemon provides a general
+ implementation of the caching done by the `rrdtool' plugin.
+
- rrdtool
Output to round-robin-database (RRD) files using librrd. See rrdtool(1).
This is likely the most popular destination for such values. Since
since collectd is programmed multithreaded it benefits from hyperthreading
and multicore processors and makes sure that the daemon isn't idle if only
one plugins waits for an IO-operation to complete.

* Once set up, hardly any maintenance is necessary. Setup is kept as easy
as possible and the default values should be okay for most users.
* CoreFoundation.framework and IOKit.framework (optional)
For compiling on Darwin in general and the `apple_sensors' plugin in
particular.
+ <http://developer.apple.com/corefoundation/>
* libcurl (optional)
If you want to use the `apache', `ascent', or `nginx' plugin.
+ <http://curl.haxx.se/>
+
+ * libdbi (optional)
+ Used by the `dbi' plugin to connect to various databases.
+ <http://libdbi.sourceforge.net/>
* libesmtp (optional)
For the `notify_email' plugin.
+ <http://www.stafford.uklinux.net/libesmtp/>
* libhal (optional)
If present, the uuid plugin will check for UUID from HAL.
+ <http://hal.freedesktop.org/>
- * libiptc (optional)
+ * libiptc (optional, if not found a version shipped with this distribution
+ can be used if the Linux kernel headers are available)
For querying iptables counters.
+ <http://netfilter.org/>
* libmysqlclient (optional)
Unsurprisingly used by the `mysql' plugin.
+ <http://dev.mysql.com/>
* libnetlink (optional)
Used, obviously, for the `netlink' plugin.
+ <http://www.linuxfoundation.org/en/Net:Iproute2>
* libnetsnmp (optional)
For the `snmp' plugin.
+ <http://www.net-snmp.org/>
* libnotify (optional)
For the `notify_desktop' plugin.
+ <http://www.galago-project.org/>
* liboping (optional, if not found a version shipped with this distribution
can be used)
Used by the `ping' plugin to send and receive ICMP packets.
+ <http://verplant.org/liboping/>
* libowcapi (optional)
Used by the `onewire' plugin to read values from onewire sensors (or the
owserver(1) daemon).
+ <http://www.owfs.org/>
* libpcap (optional)
Used to capture packets by the `dns' plugin.
+ <http://www.tcpdump.org/>
* libperl (optional)

ithread support (introduced in Perl 5.6.0).
+ <http://www.perl.org/>
* libpq (optional)
The PostgreSQL C client library used by the `postgresql' plugin.
+ <http://www.postgresql.org/>
- * librrd (optional; headers and library; rrdtool 1.0 and 1.2 both work fine)
- If built without `librrd' the resulting binary will be `client only', i.e.
- will send its values via multicast and not create any RRD files itself.
- Alternatively you can chose to write CSV-files (Comma Separated Values)
- instead.
+ * librrd (optional)
+ Used by the `rrdtool' and `rrdcached' plugins. The latter requires RRDtool
+ client support which was added after version 1.3 of RRDtool. Versions 1.0,
+ 1.2 and 1.3 are known to work with the `rrdtool' plugin.

Configuring / Compiling / Installing
`./configure && make && make install'. For detailed, generic instructions
see INSTALL. For a complete list of configure options and their description,
run `./configure --help'.

By default, the configure script will check for all build dependencies and
disable all plugins whose requirements cannot be fulfilled (any other plugin
will be enabled). To enable a plugin, install missing dependencies (see
