You can call this operation to query the monitoring data on snapshot capacity changes in a region over the past 30 days.

Description

When you call this operation, take note of the following points:

  • A maximum of 400 entries of monitoring data can be returned at a time. If the result of the (EndTime - StartTime)/Period formula is more than 400, an error is returned.
  • You can only query the monitoring data of the last 30 days. If the value of the StartTime parameter is more than 30 days ago, an error is returned.

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.
