Queries detailed information about a specified Classic Load Balancer (CLB) instance.

Note If the backend servers are deployed in a vServer group, you can call the DescribeVServerGroupAttribute operation to query the backend server.

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.
