Description

Munin is a highly flexible and powerful solution used to create graphs
of virtually everything imaginable throughout your network, while
still maintaining a rattling ease of installation and configuration.
This package contains the grapher/gatherer. You will only need one
instance of it in your network. It will periodically poll all the
nodes in your network it's aware of for data, which it in turn will
use to create graphs and HTML pages, suitable for viewing with your
graphical web browser of choice. It is also able to alert you if any
value is outside of a preset boundary, useful if you want to be
alerted if a filesystem is about to grow full, for instance. You can
do this by making Munin run an arbitrary command when you need to be
alert it, or make use of the intrinsic Nagios support. Munin is
written in Perl, and relies heavily on Tobi Oetiker's excellent
RRDtool. To see a real example of Munin in action, you can follow a
link from http://munin.projects.linpro.no/ to a live installation.

Overview

Munin is a system monitoring, network monitoring and infrastructure
monitoring software application. Munin offers monitoring and alerting
services for servers, switches, applications, and services. It alerts
the users when things go wrong and alerts them a second time when the
problem has been resolved.
