how to deal with HA Resource in a Cluster Is Going to Be Insufficient alarm on FusionCompute V1R5C00 version
This alarm is generated when the high availability (HA) resource in a cluster is going to be insufficient. This alarm is cleared when the HA resource in the cluster is sufficient. On the Real-Time Alarms page, locate the row that contains the alarm and click the cluster name in the Alarm Object column. The cluster page is displayed. Check the hosts in the cluster and restore the faulty ones. Check the non-HA VMs running in the cluster and stop the unnecessary ones. Add hosts to the cluster. Check whether the alarm is cleared.

how to deal with Host Memory Usage Exceeds the Threshold alarm on FusionCompute V1R5C00 version
The system monitors the host memory usage every 60 seconds. This alarm is generated when the system detects that the host memory usage is greater than or equal to the specified alarm threshold for three consecutive times. This alarm is cleared when the host memory usage is less than the minor alarm threshold Check the alarm thresholds for the host memory 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 Memory usage in the Entity column and check whether the alarm thresholds for the host memory usage are too low. If yes, go to Step 2. 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. After 3 or 4 minutes, switch to the Alarm page and check whether the alarm is cleared. If yes, go to Step 6. If no, go to Step 4. Migrate VMs from this host to other hosts. Migrate VMs from this host to other hosts. For details, see Migrating a VM. If no host is to be migrated, go toStep 7 After 3 or 4 minutes, switch to the Alarm page and check whether the alarm is cleared. If yes, go to Step 6. If no, go to Step 7.
