Metric tab in the entity Dashboard has 4 main actionable sections:

  1. Sparklines - Displays some convenient metrics as miniature sparkline charts. Clicking on one of the latter will load the chart in a larger dialog.
  2. A list of all metrics available for the resource. Clicking on one will display the metric chart.
  3. Controls allow you to change the rollup (Average in this example), as well as changing the Time range between hour, day or week.
  4. The chart itself. You can zoom into a particular datapoint, select a specific range of time and get feedback as you hover over the datapoints.
