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

  1. Default metrics - Displays default metrics, if available. Clicking on one of the latter will load the chart in a larger dialog.
  2. List of metrics available for the node. Clicking on one will load the selected metricĀ in a larger dialog.
  3. These options allow you to affect the chart data, You can change the rollup (Average in this example), as well as changing the Time range between hour, day or week.
  4. The chart itself is intractable. You can zoom into a particular datapoint, select a specific range of time and get feedback as you hover over the datapoints.
