Overview of Workload Experience Manager
Workload Experience Manager (Workload XM) is a tool that provides insights to help you gain in-depth understanding of the workloads you send to clusters managed by Cloudera Manager. In addition, it provides information that can be used for troubleshooting failed jobs and optimizing slow jobs that run on those clusters. After a job ends, information about job execution is sent to Workload XM with the Telemetry Publisher, a role in the Cloudera Manager Management Service.
Workload XM uses the information to display metrics about the performance of a job. Additionally, Workload XM compares the current run of a job to previous runs of the same job by creating baselines. You can use the knowledge gained from this information to identify and address abnormal or degraded performance or potential performance improvements.
Default Time Range
If you have not specified a time range, Workload Experience Manager (Workload XM) displays data for the last 24 hours by default. If there is no data available for the last 24 hours, Workload XM displays the full range that is available by default.
