The munin homepage is http://munin.projects.linpro.no/ - -To use this module, follow these directions: - -0. This module requires puppet 2.7 or newer. - -1. Install the "common", "concat" and "stdlib" modules -- the munin module - depends on functions that are defined and installed via these modules. - -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. For every host you wish to gather munin statistics, add the class munin::client to that - node. You will want to set the class parameter 'allow' to be the IP(s) of the munin - collector, this defines what IP is permitted to connect to the node, for example: - - node foo { - class { 'munin::client': allow => '192.168.0.1'} - } - - for multiple munin nodes, you can pass an array: - - class { 'munin::client': allow => [ '192.168.0.1', '10.0.0.1' ] } - - c. In the node definition in your site.pp for your main munin host, add the following: - - class { 'munin::host': } - - If you want cgi graphing you can pass cgi_graphing => true. - (For CentOS this is enabled in the default header config) - for more information, see: http://munin.projects.linpro.no/wiki/CgiHowto - - d. 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 => present, - script_path => '/usr/local/share/munin-plugins', - } - - # For wildcard plugins (eg. ip_, snmp_, etc.), use the name variable to - # configure the plugin name, and the ensure parameter to indicate the base - # plugin name to which you want a symlink, for example: - munin::plugin { [ 'ip_192.168.0.1', 'ip_10.0.0.1' ]: - ensure => 'ip_' - } - - # Use a special config to pass parameters to the plugin - munin::plugin { - [ 'apache_accesses', 'apache_processes', 'apache_volume' ]: - ensure => present, - config => 'env.url http://127.0.0.1:80/server-status?auto' - } - - e. 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 class parameter: - - class { 'munin::client': allow => '192.168.0.1', port => '4948' } - |
