Hello,

In our environment, we have a few servers that we need to use separate CPU utilization thresholds. I have configured a separate host group and assigned the services to it, which is nested in our main server group, and configured to use 100% as warning and critical. However, only 1 server seems to be inheriting this change. Any thoughts or ideas are appreciated!

Details:
Main Host Group -> CPU Usage 10,80,90 (10 Min Average, 80% Warn, 90% Critical)
Nested Host Group -> CPU Usage 10,100,100 (10 Min Average, 100% Warn, 100% Critical)

Both Servers in Nested Group, but one is not inheriting the more "specific check"

Server 1 - Perf Data (Not Working)
Performance Data: '10 min avg Load'=98%;80;90;0;100 (Derived from Main Host Group)

Server 2 - Perf Data
Performance Data: '10 min avg Load'=0%;100;100;0;100 (Derived Correctly from Nested Host Group)

In the service that has the Main Host Group assigned you need to add the hosts as exclusions.

In the CCM you would go to the service, click on the blue "Manage Hosts" button, select the hosts in Nested Host Group and check the excluded box
Ok
Save
Apply Configuration


Currently I think the services are applies to both and it's a race condition on startup to which gets assigned first.

Thank you for the information.

I don't see "exclude" I only see "assigned" with the option of "+, Null or Standard".

I was falsely under the assumption that nested checks would simply use the check "nearest" to the host in the case of multiple checks/thresholds.

Regards,
Mike

After you click "Add Selected" on the right side there will be a check box next to the host with a ! next to it. you check the box

Thank you! (working as expected)

glad to hear it's working!
