Understanding Workload XM
Workload XM is a Cloudera service that helps you understand the workloads that you process, the clusters and services that manage those workloads, and the data that is processed. Workload XM provides information that helps you troubleshoot failed jobs and optimize slow jobs that run on your Workload clusters. When a job completes, information about the job and the cluster that processed the job is sent to Workload XM with Telemetry Publisher, a role in the Cloudera Manager Management Service.
Workload XM also displays metrics about a job's performance and compares the current job run with previous runs by creating baselines. This information helps you identify and address abnormal or degraded performance.
