If you do not need monitoring alerts or certain metrics in Realtime Compute for Apache Flink, you can disable monitoring alerts for a workspace or discard specific metrics to reduce costs. You can resume metric collection when needed. This topic describes how to disable and enable monitoring alerts, and how to discard and restore metrics.
Usage notes
-
If you use a RAM user or a RAM role, you must have permissions to access Application Real-Time Monitoring Service (ARMS). For more information, see Access control overview.
