You can call this operation to query the specified performance metrics of an instance over a specified time range.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

Parameter Type Required Example Description
DBInstanceId String Yes gp-xxxxxxxx

The ID of the instance.
EndTime String Yes 2018-07-09T03:47Z

The end of the time range to query. Example: 2018-06-11T16:00Z.
Key String Yes CpuUsage,MemoryUsage,Gpdb_SpaceUsage,Gpdb_IOPS,Gpdb_session

The performance metrics. Separate multiple performance metrics with commas (,). For more information, see Performance parameters.
