+Munin is a performance monitoring system which creates nice RRD graphs and has
+a very easy plugin interface. The munin homepage is
+To use this module, follow these directions:
+1. Install the "common" module -- the munin module depends on functions that are
+ defined and installed via the common module, see README.common for how to do this
+2. You will need storedconfigs enabled in your puppet setup, to do that you need to
+ add a line to your puppet.conf in your [puppetmasterd] section which says:
+ storeconfigs=true
+ You may wish to immediately setup a mysql/pgsql database for your storedconfigs, as
+ the default method uses sqlite, and is not very efficient, to do that you need lines
+ such as the following below the storeconfigs=true line (adjust as needed):
+ dbadapter=mysql
+ dbserver=localhost
+ dbuser=puppet
+ dbpassword=puppetspasswd
+3. Install the "munin" module:
+ a. Your modules directory will need all the files included in this repository placed
+ under a directory called "munin"
+ b. add the following line to your modules.pp:
+ import "munin"
+ (NOTE: if you have followed the directions in README.common then you will have import
+ "modules.pp" in your site.pp, if you do not have that, then you will need to add the
+ import line to your site.pp)
+ c. you will also need to create the following empty directories:
+ mkdir /etc/puppet/modules/munin/files/empty
+ mkdir /etc/puppet/modules/munin/files/modules_dir
+ mkdir -p /etc/puppet/modules/munin/files/nodes/modules_dir
+ mkdir -p /etc/puppet/modules/munin/files/plugins/modules_dir
+ d. Add to the top of your site.pp a variable which indicates what IP should be allowed to
+ connect to your individual munin-nodes (this is typically your main munin host's IP):
+ $munin_allow = ''
+ e. In the node definition in your site.pp for your main munin host, add the following:
+ include munin::host
+ f. On each node that will gather munin statistics, add this line to that node's entry
+ in site.pp (you may want to also add this to your main munin host):
+ include munin::client
+ g. If there are particular munin plugins you want to enable or configure, you define them
+ in the node definition, like follows:
+ # Enable monitoring of disk stats in bytes
+ munin::plugin { df_abs: }
+ # Use a non-standard plugin path to use custom plugins
+ munin::plugin { "spamassassin":
+ ensure => "spamassassin",
+ script_path => "/usr/local/share/munin-plugins",
+ }
+ # Use a special config to pass parameters to the plugin
+ munin::plugin {
+ [ "apache_accesses", "apache_processes", "apache_volume" ]:
+ ensure => present,
+ config => "env.url"
+ }
+ h. If you have Linux-Vservers configured, you will likely have multiple munin-node processes
+ competing for the default port 4949, for those nodes, set an alternate port for munin-node
+ to run on by putting something similar to the following in the node definition:
+ $munin_port = 4948
