Usage
=====

There's a difference between JSON dashboard representation and models we us. Lists are replaced by dictionaries to support mergings and interpolations.

The default format of Grafana dashboards with lists for rows, panels and targets.

.. code-block:: yaml

    system_metrics:
      title: graph
      editable: true
      hideControls: false
      rows:
      - title: Usage
        height: 250px
        panels:
        - title: Panel Title
          span: 6
          editable: false
          type: graph
          targets: 
          - refId: A
            target: "support_prd.cfg01_iot_tcpcloud_eu.cpu.0.idle"
          datasource: graphite01
          renderer: flot
        showTitle: true


The modified version of Grafana dashboard format that supports character interpolation.

.. code-block:: yaml

    system_metrics:
        system_metrics2:
          title: graph
          editable: true
          hideControls: false
          row:
            usage:
              title: Usage
              height: 250px
              panel:
                usage-panel:
                  title: Panel Title
                  span: 6
                  editable: false
                  type: graph
                  target:
                    A:
                      refId: A
                      target: "support_prd.cfg01_iot_tcpcloud_eu.cpu.0.idle"
