Viewing Default Metric Charts for a Metric Namespace (Multiple Resources)
Go to the Service Metrics page in the Console to view metric charts that use predefined service queries for a selected metric namespace. The charts show metric data for all resources in the selected metric namespace, compartment, and region.
The Service Metrics page displays default charts for all resources in the selected region and compartment that emit metric data to the selected metric namespace.
You can update the query by adding or editing dimensions, by aggregating metric streams, or by opening the chart in the Metrics Explorer page for advanced query updates. You can also create an alarm based on the query.
