Key Features of Workload XM

Lists the key features of Workload XM.

Default Time Range
Workload XM enables you to choose a time period in which your workload results are displayed for analysis and troubleshooting.
Understanding the Clusters Page
Describes the features in the Clusters page, which lists your clusters, the services that use them, the last time they were updated, and whether you enabled the daily cluster report.
File Size Reporting
The file size reporting feature in Workload XM enables you to identify databases and tables where the data is stored inefficiently, such as in small files or partitions, that can cause performance issues.
Understanding the Baseline Metric
Describes the Baseline metric feature of the engine's Jobs page.
Spark RDD Health Check
The Spark RDD health check informs you when you have redundant Resilient Distributed Datasets (RDD) cache. Workload XM displays the location of the cache so that you can remove it and save executor memory.
Analyze Workloads from Auto-Generated Workload Views
Describes how to access the auto-generated predefined Workload XM workload views, which enable you to immediately start analyzing jobs on your cluster without having to perform an initial analysis that determines which criteria to use when creating a new workload view.
Workload Classification for Deep-dive Analysis
Describes how to access the Workload XM workload view feature where you define your workload views.
Comparing a Job with the Previous Run
Describes how to access the Job Comparison feature, which compares two different runs of the same job.
Repair Table Statistic Issues
When your queries trigger either the Corrupt Table Statistics or the Missing Table Statistics health checks, Workload XM generates SQL code for you to copy and run on your cluster to address these issues.
Suppress Sensitive Data
The suppression of sensitive data is controlled by setting the log and query redaction configuration in Cloudera Manager for the Telemetry Publisher service. By default, this configuration is enabled.
Proxy Server Support for Telemetry Publisher
You can configure the Telemetry Publisher service to send metrics as well as configuration and log files to Workload XM by way of a proxy server for database and Altus metrics uploads. This intermediary gateway also adds extra security when sending your workload data to Workload XM.
