Question by Tamás V. · Feb 25, 2014 at 02:00 PM ·

Host CPU Unhealthy incident

Hi,

We always get "Host CPU Unhealthy" severe incident report from our dT 5.6 environment.

It says "The CPU health of host **** is not ok. During the last 16 minutes the host reported a high overall CPU usage of 99%, a load greater than 2 (unix based systems only) or more than 15% system CPU.

I created a new incident with a CPU total time > x condition, but in Host information we'll see only the default one. Can i change the default somehow? I believe the 15% is too low, and thus the CPU usage is always in red (however the cpu usage is usually between 20-40%).

Best regards,
Tamas

You can change the thresholds used for the CPU Unhealthy incident (see the documentation Host Health Monitoring for the relevant property - should be healthCPUSystemThreshold). Please note that this is a global setting and affects all hosts.
