**To get resource metrics**

This example requests data points for the *db.wait_event* dimension group, and for the *db.wait_event.name* dimension within that group. In the response, the relevant data points are grouped by the requested dimension (*db.wait_event.name*).



Command::

  aws pi get-resource-metrics --service-type RDS --identifier db-LKCGOBK26374TPTDFXOIWVCPPM --start-time 1527026400 --end-time 1527080400 --period-in-seconds 300 --metric db.load.avg --metric-queries file://metric-queries.json

The arguments for ``--metric-queries`` are stored in a JSON file, ``metric-queries.json``.  Here are the contents of that file::

  [
      {
          "Metric": "db.load.avg",
          "GroupBy": { 
              "Group":"db.wait_event" 
          }
      }
  ]


Output::
