.SH DESCRIPTION
.IX Header "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.
.PP
Munin-update does the gathering. It is usually only used from within
munin-cron.
.PP
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.
