You can call this operation to query the WebSocket network traffic monitoring data. The maximum time range that can be specified is the last 90 days.

When you call this operation, follow these rules:
  • If you do not specify the StartTime and EndTime parameters, the data within the last 24 hours is queried. If you specify the StartTime and EndTime parameters, the data within the specified time range is queried.
  • You can specify multiple accelerated domain names and separate them with commas (,).
  • The data is measured in bytes.

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.
