13.12. Using Servicegroups to Group Related Services

Problem

Some of your servers are running multiple services, and on the Nagios web interface, you want to see related services grouped together (e.g., SSH, FTP, HTTP, and anything you have running on multiple servers).

Solution

Create servicegroups. You can group together any host or service combinations you like. This example shows an SSH servicegroup:

	# ssh servicegroup
	define servicegroup{
	  servicegroup_name      ssh
	  alias                  all ssh servers
	  members              uberpc,SSH,stinkpad,SSH
	}

The members must already have service definitions in services.cfg. You may group together any combination of host/service pairs.

When you're finished, run the syntax-checker, and restart Nagios:

	# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
	# /etc/init.d/nagios restart

Then, click on the various "Servicegroup" links on the Nagios web interface to see them.

Discussion

The services don't have to all be the same; you can group any services you want. The members definitions are case-sensitive, so make sure they match their host and service definitions.
