Default: '/root/check_mk' +## Host groups and tags + +By default check_mk puts all hosts into a group called 'check_mk' but where you +have more than a few you will often want your own groups. We can do this by +setting host tags on the agents and then configuring hos groups on the server +side to match hosts with these tags. + +For example in the hiera config for your agent hosts you could have: + + check_mk::agent::host_tags: + - '%{osfamily}' + +and on the monitoring host you could have: + + check_mk::host_groups: + RedHat: + description: 'RedHat or_CentOS hosts' + host_tags: + - RedHat + Debian: + description: 'Debian or Ubuntu_hosts' + host_tags: + - Debian + SuSE: + description: 'SuSE hosts' + host_tags: + - Suse + +You can of course have as many host tags as you like.

To manually include these hosts you can +add them to '/omd/sites/monitoring/etc/check_mk/all_hosts_static' (replacing +'monitoring' with your site name).
