Metric Visualizations look like display text and have to do with throughput such as incoming throughput of data, message throughput, processing throughput, throughput over time. When your intention is to add a metric-type visualization to a dashboard, the most expedient way to narrow the resource options to those pertinent to your objective, is to filter the resources by the search term "throughput."  This is illustrated in the procedures that follow.

Adding a Metric Visualization

To add a metric widget to a dashboard:

  1. Open the dashboard (e.g., Performance Matrix) to which you want to add a metric widget by browsing to Dashboards > Performance Matrix.
  2. Click Edit to make all of the widgets on the dashboard editable.
  3. Click Add Widget > Metric Widget.
  4. Click Show Visualization to open the Visualization Editor, if it is not already open.
  5. In the General section of the Visualization Editor, select the Visualization Type Metric, if it's not already selected.
    Notice that the Metric Source field does not have a text entry box or dropdown options.  When you choose a source, the options become available.
  6. Click the Resources icon to open the Resources pane and expose folders containing the Queries and Tables on your Lumeta system.
  7. Open the Queries folder.
  8. In the Search field, type "throughput" to find pertinent queries.
