Collecting Workload Manager Diagnostic Metrics
When you enable Workload Analytics for Workload Manager, the Cloudera Management Service starts the Telemetry Publisher and the Databus Producer role. Telemetry Publisher and Databus Producer collect and transmit metrics, as well as configuration and log files, to Workload Manager from Impala, Oozie, Hive, YARN, and Spark services for jobs running on your clusters. Telemetry Publisher and Databus Producer collect metrics for all the clusters that use Workload Manager-enabled environments.
