Management Dashboard provides a set of Oracle-defined widgets for the Observability & Management services it supports and enables you to create custom widgets that meet your specific requirements.

Oracle-defined widgets are ready-to-use visualization tools that display a wide variety of data and functionality to monitor your resources. Here's information about a few Oracle-defined widgets that you can use to monitor all supported Observability & Management service resources:

• Metric line chart: Enables you to quickly specify input parameters such as Namespace and Metric name and visualize the metric data stored in the Oracle Cloud Infrastructure Monitoring service, in a line chart.
• Resources table: Lists the Oracle Cloud Infrastructure resources and common attributes returned using a resource query, in a table.
• Resources pie chart: Lists the Oracle Cloud Infrastructure resources and common attributes returned using a resource query, in a pie chart. By default, the Resources pie chart widget displays resources grouped by lifecycle state, however, you can edit the configured Group by widget input and select other options such as Resource type or Availability Domain.
