Say there’s a hostgroup defined on a Nagios server; and that hostgroup has a notification set up to go off when a certain service or services reach a critical state then a notification email will be sent out to a contact stating that it should be looked at. Does this sort of functionalty exist in Nagios XI?
Answer
No.
Hostgroups and Servicegroups are for grouping objects in the web interface, and for simplifying configuration (in core, anyway) by allowing services, escalations, dependencies, etc., to be assigned to groups.
What you’re describing sounds more like check_multi or possibly check_cluster (see docs page about monitoring clusters for more info).
