Discard or restore metrics - Realtime Compute for Apache Flink

Realtime Compute for Apache Flink provides the Prometheus service for workspaces. If you no longer require the Prometheus service for a workspace or a metric for deployments in fully managed Flink, you can disable the Prometheus service or discard the metric. This helps reduce monitoring costs. You can restore the metric that you discard based on your business requirements. This topic describes how to disable and enable the Prometheus service and how to discard and restore a metric.

Important notes

If you use a RAM user or RAM role to access fully managed Flink, the RAM user or RAM role must have the permissions to access Application Real-Time Monitoring Service (ARMS). For more information, see Overview.
This feature is available for workspaces that has enabled Managed Service for Prometheus.

2. Find your workspace and select > Monitoring Indicator Configuration in the Actions column to go to the ARMS console.
3. Click the icon in the upper-left corner of the Service Discovery page to go to the Managed Service for Prometheus page. The name in the upper-left corner of the Service Discovery page is the name of the Prometheus instance that corresponds to the workspace.
Disable or enable the Prometheus service.
