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.

Network latency: Time to reach the default gateway or another given

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.
