Input plugins are queried periodically. They somehow acquire the current value
of whatever they where designed to work with and submit these values back to
reads the current cpu-counters of time spent in the various modes (user,
system, nice, ...) and dispatches these counters to the daemon.

Output plugins get the dispatched values from the daemon and does something
with them. Common applications are writing to RRD-files, CSV-files or sending
to the RRD files. This is the same as using the C<FLUSH -1> command of the
C<unixsock plugin>.
