Creating a Dashboard

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, you can add routine O&M metrics to a dashboard so that you can perform routine checks without re-selecting metrics when you open AOM again.

Precautions

Preset dashboard templates are listed under System, including the container, cloud service, native middleware, and application templates. Preset dashboards cannot be deleted. Their groups cannot be changed. Dashboard templates cannot be created.
Up to 1,000 dashboard groups can be created in a region.
Up to 1,000 dashboards can be created in a region.
A maximum of 30 graphs can be added to a dashboard.
A maximum of 200 metric data records can be displayed in a line graph.
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.
