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).
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.
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).
+ * libpq (optional)
+ The PostgreSQL C client library used by the `postgresql' plugin.
+
* 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.
+ * 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
------------------------------------
disable all plugins whose requirements cannot be fulfilled (any other plugin
will be enabled). To enable a plugin, install missing dependencies (see
section `Prerequisites' above) and rerun `configure'. If you specify the
- `--enable-<plugin>' configure option, you can force the plugin to be built.
- This will most likely fail though unless you're working in a very unusual
- setup and you really know what you're doing.
+ `--enable-<plugin>' configure option, the script will fail if the depen-
+ dencies for the specified plugin are not met. If you specify the
+ `--disable-<plugin>' configure option, the plugin will not be built. Both
+ options are meant for package maintainers and should not be used in everyday
+ situations.
By default, collectd will be installed into `/opt/collectd'. You can adjust
this setting by specifying the `--prefix' configure option - see INSTALL for
