See collectd-exec(5).
+ - filecount
+ Count the number of files in directories.
+
- hddtemp
Harddisk temperatures using hddtempd.
Network UPS tools: UPS current, voltage, power, charge, utilisation,
temperature, etc. See upsd(8).
+ - onewire (EXPERIMENTAL!)
+ Read onewire sensors using the owcapu library of the owfs project.
+ Please read in collectd.conf(5) why this plugin is experimental.
+
- perl
The perl plugin implements a Perl-interpreter into collectd. You can
write your own plugins in Perl and return arbitrary values using this
Network latency: Time to reach the default gateway or another given
host.
+ - postgresql
+ PostgreSQL database statistics: active server connections, transaction
+ numbers, block IO, table row manipulations.
+
- processes
Process counts: Number of running, sleeping, zombie, ... processes.
* Notifications can be handled by the following plugins:
- - desktop_notification
+ - notify_desktop
Send a desktop notification to a notification daemon, as defined in
the Desktop Notification Specification. To actually display the
notifications, notification-daemon is required.
See http://www.galago-project.org/specs/notification/.
+ - notify_email
+ Send an E-mail with the notification message to the configured
+ recipients.
+
- exec
Execute a program or script to handle the notification.
See collectd-exec(5).
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.
used and should be found in various implementations for hopefully all
platforms.
+ * CoreFoundation.framework and IOKit.framework (optional)
+ For compiling on Darwin in general and the `apple_sensors' plugin in
+ particular.
+
* libcurl (optional)
If you want to use the `apache', `ascent', or `nginx' plugin.
+ * libesmtp (optional)
+ For the `notify_email' plugin.
+
* libhal (optional)
If present, the uuid plugin will check for UUID from HAL.
- * 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.
* libmysqlclient (optional)
For the `snmp' plugin.
* libnotify (optional)
- For the `desktop_notification' plugin.
+ For the `notify_desktop' plugin.
* 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.
+ * libowcapi (optional)
+ Used by the `onewire' plugin to read values from onewire sensors (or the
+ owserver(1) daemon).
+
* libpcap (optional)
Used to capture packets by the `dns' plugin.
Obviously used by the `perl' plugin. The library has to be compiled with
ithread support (introduced in Perl 5.6.0).
- * 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.
+ * libpq (optional)
+ The PostgreSQL C client library used by the `postgresql' plugin.
+
+ * librrd (optional)
+ Used by the `rrdtool' and `rrdcached' plugins. The latter requires RRDtool

+ * librt, libsocket, libkstat, libdevinfo (optional)
+ Various standard Solaris libraries which provide system functions.
* libsensors (optional)
To read from `lm_sensors', see the `sensors' plugin.
- * libstatgrab may be used to collect statistics on systems other than Linux
- and/or Solaris. Note that CPU- and disk-statistics, while being provided
- by this library, are not supported in collectd right now..

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
