+== Creating a nagios monitor ==
+This page explains how to create a nagios monitor configuration in [wiki:how-to/puppet puppet].  You will need to make changes to get the correct configuration for the type of monitoring.  
+
+=== Set up an executable ===
+These files are stored in puppet/modules/mayfirst/files/monitor-utils/ you can
+find examples of different versions of monitoring scripts there.
+
+=== Set up a cronjob ===
+projects/puppet/modules/mayfirst/templates/monitor-utils/cron.d/mf-monitor
+
+You'll need to add your script to this directory.
+
+=== Add to utils.pp ===
+puppet/modules/mayfirst/manifests/utils.pp
+
+The code should look something like this, with the correct file from the executable specified.:
+
+{{{
+  file { "/usr/local/sbin/mf-monitor-mailq":
+    source => "puppet:///modules/mayfirst/monitor-utils/mf-monitor-mailq",
+    ensure => present,
+    mode => 755,
+    owner => "root",
+    group => "root"
+  }
+}}}
+
+=== Define hostgroup ===
+projects/puppet/modules/mayfirst/files/nagios/nagios3/conf.d/
+
+This code section should look something like this:
+
+{{{
+define hostgroup {
+  hostgroup_name  mailq-servers
+  alias           Mail Check Servers
+}
+}}}
+
+=== Define nagios command ===
+puppet/modules/mayfirst/files/nagios/nagios3/commands.cfg
+
+Should look like this:
+
+{{{
+define command{
+  command_name    check-upgrade
+  command_line    /usr/local/share/nagios/plugins/mf-nagios-check-upgrade '$HOSTNAME$'
+}
+}}}
+=== Create parsing script ===
+You will also need to create a script that parses the output of the monitoring
+files.
+
+projects/puppet/modules/mayfirst/files/nagios/nagios-plugins/plugins/mf-SCRIPT-NAME
+
+You can model scripts that already exist to check this.
+
+=== Finally add the hostgroup to nagios manifest ===
+
+projects/puppet/modules/mayfirst/manifests/nagios.pp
+
+One example for standard_hostgroups is:
+{{{
+  if ( $include_standard_hostgroups == true ) {
+    $standard_hostgroups = [ 'df-servers', 'upgrade-servers', 'mailq-servers' ]
+    $assigned_hostgroups = concat($hostgroups, $standard_hostgroups)
+  } else {
+    $assigned_hostgroups = $hostgroups
+    
+  }
+}}}
+
+This is from 'define m_nagios_host'.
+
+'''Make sure all executable scripts have execute permissions'''
