how to deal with Memory Reservation Rate Exceeds the Threshold alarm on FusionCompute V1R5C00 version

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

This alarm is cleared when the host memory reservation rate is less than the alarm threshold.
Check the alarm threshold for the memory reservation rate.

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 Memory reservation rate in the Entity column and check whether the alarm threshold for the host memory reservation rate is too low.

If no, go to Step 4.

Adjust the alarm thresholds and check whether the alarm is cleared. For details about alarm threshold adjustment, see Configuring Alarm Thresholds.
