a: If a service has multiple dimensions, all dimensions are mandatory when you use APIs to query the metrics.

  • Example of querying a single metric from both dimensions: dim.0=lbaas_instance_id,223e9eed-2b02-4ed2-a126-7e806a6fee1f&dim.1=lbaas_listener_id,3baa7335-8886-4867-8481-7cbba967a917
  • Example of querying metrics in batches from both dimensions:
    "dimensions": [
    {
    "name": "lbaas_instance_id",
    "value": "223e9eed-2b02-4ed2-a126-7e806a6fee1f"
    }
    {
    "name": "lbaas_listener_id",
    "value": "3baa7335-8886-4867-8481-7cbba967a917"
    }
    ],
