CPU threshold is not triggering alert/event

I have configured a CPU threshold

I then stress test my server which peaks the CPU (all cores) to 70%.
The same is being reflected on the OpenNMS resource graph under CPU utilization.

However, there is no alert/event triggered for this. I expected an event created on the Web UI as the CPU has exceeded 50%. as per the threshold.

I have checked the notification bullet: ON

how can I troubleshoot this?

PS: The memory threshold is working fine for the same server.

OpenNMS version:

Show the threshold configuration.

Hi, Thanks for your response. I have fixed it now.
The issue was I had created a new Threshold group and did not add the OIDs of CPU in thrsd config file.
