ALM-50205 BE CPU Usage Exceeds the Threshold

Alarm Description

The system checks the CPU usage of the BE instance every 30 seconds. This alarm is generated when the CPU usage exceeds the threshold for multiple consecutive times (3 by default).

This alarm is cleared when Trigger Count is 1 and the CPU usage is less than or equal to the threshold. This alarm is cleared when Trigger Count is greater than 1 and the CPU usage is less than or equal to 80% of the threshold.

2. Click the edit button next to Trigger Count, change the number based on site requirements, and click OK.
   

   Trigger Count specifies how many times the threshold can be hit before an alarm is generated.

3. Click Modify in the Operation column, change the alarm threshold based on site requirements, and click OK.
4. Wait 2 minutes and check whether the alarm is automatically cleared.
   • If yes, no further action is required.
