DESCRIPTION
Munin-update is a part of the package Munin, which is used in combination with Munin's node. Munin is a group of programs to gather data
from Munin's nodes, graph them, create html-pages, and optionally warn Nagios about any off-limit values.
Munin-update does the gathering. It is usually only used from within munin-cron.
It contacts each host's munin-node in turn, gathers data from it, and stores them in .rrd-files. If necessary, it will create the rrd-files
and the directories to store them in.
