You need to focus on CPU, memory, and storage space usage.
You can configure DDS to report alarms as needed. If an alarm is reported, you can take proper measures to clear it.
Configuration examples:
- Configure DDS to report alarms to CES if CPU utilization reaching or exceeding a certain value (90% for example) for multiple times (3 for example) within a period of time (5 minutes for example).
- Configure DDS to report alarms to CES if memory utilization reaching or exceeding a certain value (90% for example) for multiple times (4 for example) within a period of time (5 minutes for example).
- Configure DDS to report alarms to CES if storage utilization reaching or exceeding a certain value (85% for example) for multiple times (5 for example) within a period of time (5 minutes for example).

NOTE:For details on CES alarm configuration, see "Alarm Rule Management" in Elastic Cloud Server User Guide.
Measures:
If a storage usage alarm is reported, perform either of the following operations:
- Check the storage space consumption and see whether any space can be freed up by deleting data from DB instances or dumping the data to another system.
- Scale up the storage space. For details, see Increasing Storage.
