3. Output Parameters

Parameter Name	Type	Description
TotalCount	Integer	Total number of CLB instances that meet the filter criteria. This value is independent of the Limit in the input parameter.
LoadBalancerSet	Array of LoadBalancer	Array of returned CLB instances.
RequestId	String	The unique request ID, which is returned for each request. RequestId is required for locating a problem.

4. Example

Example1 Querying the CLB instance with a specified private IP of the real server bound to it
