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

-  Query a single metric:

   .. code-block::

      dim.0=er_instance_id,d9f7b61f-e211-4bce-ac5f-2b76f3d0cf1d&dim.1=er_attachment_id,659614a0-e559-46c0-86ca-00c03c3d61b8

-  Query metrics in batches:

   .. code-block::

      "dimensions": [
          {
              "name": "er_instance_id",
              "value": "d9f7b61f-e211-4bce-ac5f-2b76f3d0cf1d"
          },
          {
              "name": "er_attachment_id",
              "value": "659614a0-e559-46c0-86ca-00c03c3d61b8"
          }
      ]

er_instance_id   Enterprise router
er_attachment_id Attachment

-  The monitoring metric measurement dimension of an enterprise router is **er_instance_id**.
-  The monitoring metric measurement dimensions of an attachment are **er_instance_id** and **er_attachment_id**.
