how to deal with Host CPU Usage Exceeds the Threshold alarm on FusionCompute V1R5C00 version

The system monitors the host CPU usage every 60 seconds. This alarm is generated when the system detects that the host CPU usage is greater than or equal to the specified alarm threshold for three consecutive times.

This alarm is cleared when the host CPU usage is less than the minor alarm threshold
Check the alarm thresholds for the host CPU usage.

On the FusionCompute, choose System > Service Configuration, expand Alarm in the Configuration Item area on the left, and select Alarm Threshold.
On the Alarm Threshold page, expand CPU usage in the Entity column and check whether the alarm thresholds for the host CPU usage are too low.
