check_puppetmaster ================== Nagios checking script that generates a warning or error if one or more nodes hasn't checked in with the master for a specified time. This script is licensed under the terms of the GPL. Please see http://www.gnu.org/copyleft/gpl.html for full details. You can obtain the latest version of this script via the repository at https://github.com/cafuego/check_puppetmaster == INSTALLATION == Plonk check_puppetmaster in /usr/lib/nagios/plugins or symlink it there from your preferred installation location. I use /usr/local/bin. Install default as /etc/default/check_puppetmaster. == CONFIGURATION == Configuration is pretty straightforward. You need to add a command on your nagios server that can run the check_puppetmaster plugin on your puppetmaster host. You will want to (for nagios2 at least) specify a command, a service and a hostgroup. Here are mine: define command { command_name check_puppetmaster command_line /usr/local/sbin/check_remote_plugin $HOSTADDRESS$ check_puppetmaster } define service { hostgroup_name puppetmasters service_description Puppet - Master Server check_command check_puppetmaster use generic-service } define hostgroup { hostgroup_name puppetmasters alias Puppet Master Servers members kanies, beaker, turnbull } Finally, you may want to override settings via /etc/default/check_puppetmaster as your configuration may not match mine, which is what the defaults work with. Importantly, add any FQDNs to the IGNORE_HOSTS variable for systems that are managed via puppet but that may not be online 24/7, such as laptops. This will avoid warnings or critical notifications if these systems haven't checked in for a while.
