Creating a Dashboard

Updated on 2024-04-15 GMT+08:00

With a dashboard, different graphs (such as line graphs and digit graphs) are displayed on the same screen, so you can view metric data comprehensively.

You can add key resource metrics to a dashboard and monitor them in real time. You can also compare the same metric of different resources on one screen. In addition, by adding common O&M metrics to a dashboard, you do not need to reselect them when re-opening the monitoring center during routine O&M.

Precautions

  • Preset dashboard templates are saved in the built-in group, including the cloud service and application templates. Preset dashboards cannot be deleted. Their groups cannot be changed. Dashboard templates cannot be created.
  • Up to 50 dashboard groups can be created in a region.
  • Up to 500 dashboards can be created in a region.
  • A maximum of 30 graphs can be added to a dashboard.
  • A maximum of 12 resources can be added to a digit graph. Only one resource can be displayed. By default, the first resource is displayed.
  • A maximum of 10 threshold rules can be added to a threshold status graph.
  • A maximum of 10 hosts can be added to a host status graph.
  • A maximum of 10 components can be added to a component status graph.

Creating a Dashboard

  1. On the menu bar, choose Monitoring Center.
  2. In the navigation pane, choose Dashboard.
  3. Click next to Dashboard to create a dashboard group.
  4. Click Add Dashboard in the upper left corner of the list.
