I have 5 servers under an agent group. I need to create an Incident only for one of the servers in the group , for a high CPU condition. I am not worried about the other 4 at all. How to do that ? Looks a simple scenario, but somehow I am missing something
I guess this is not possible under the 'Host Performance' measure because it is for the system profile / all agent groups.
If we take the 'Server Side Performance' measure then we can select the specific 'Agent Group' but even though it will not be the same you are looking for.
You can specify separate Host thresholds under the main Settings section. In there is 'Infrastructure' settings. This is where all Hosts are listed regardless of system profile. By default all Hosts have thresholds set against the Default HostGroup.
Un-tick the 'Use Thresholds of the Selected HostGroup....' and then you'll be able to specify thresholds just for that particular Host.
If you would like to continue using custom incident rules and only alerting on a specific host consider using the extended email action plugin instead of the out of the box email action. This one allows you to do a lot more filtering on the emails and you can specify which host you want to receive the alert on.
