241
Munin-nagios is a part of the package Munin, which is used in combination
242
with Munin's node. Munin is a group of programs to gather data from
243
Munin's nodes, graph them, create html-pages, and optionally warn Nagios
244
about any off-limit values.
246
Munin-nagios can warn any nagios-servers about off-limit values.
248
If a service has fields with "warning" or "critical"-options (e.g. "load.warning 10"), and the munin-server
249
configuration file contains the necessary configuration options, munin-nagios will warn the nagios-server.
253
The configuration file "munin.conf" must have the following optinons set correctly for munin-nagios to work:
255
nsca /usr/bin/send_nsca
256
nsca_server nagios-server.your.dom
257
nsca_config /etc/nagios/send_nsca.cfg
259
In addition NSCA must be installed and configured correctly.
