munin.conf - Munin configuration file

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.conf is the configuration file for Munin; munin-update, munin-graph, munin-nagios and munin-html.

The format of the file is simple. A minimal configuration looks something like:

        dbdir           /var/lib/munin
        logdir          /var/log/munin
        htmldir         /var/www/munin
        tmpldir         /etc/munin/templates/

        [machine1.your.dom]
                address localhost

The default location of munin.conf is @@CONFDIR@@/munin.conf. If your placement deviates from this norm, use the "--config <file>"-option when running the munin-* programs.

Munin-update will expand all node-entries in this file, and save them to @@DBDIR@@/datafile, which is used by all programs in the package together with this file.

Any options in this file will override options of the same name in datafile. E.g., if you want to change the title of the load-graph in the above minimum configuration, you would modify the two bottom lines to:

        [machine1.your.dom]
                address localhost
                load.graph_title Edited title of the load-graph

This will override the graph_title field of the load-service, while keeping all the others at their default.

NOTE: On all the examples below, all the 'top-level' parameters (dbdir, logdir, htmldir, tmpldir) are not present. They are only skipped for brevity - they are needed.

An example with three servers on two domains:

        [machine1.one.dom]
                address machine1.one.dom

        [machine2.one.dom]
                address 10.33.32.123

        [machine3.two.dom]
                address localhost

This will appear as two domains (one.dom and two.dom), having respectively two and one host.

Summarize the 'load'-graphs of the two servers in one.dom, in a 'total load'-graph.

        [one.dom;Totals]
                update no
                load.graph_title Total load
                load.sum_load.title load
                load.sum_load.special_stack machine1=machine1.one.dom:load.load machine2=machine2.one.dom:load.load
