Luca Canali created SPARK-26928:
-----------------------------------
Summary: Add driver CPU Time to the metrics system
Key: SPARK-26928
URL: https://issues.apache.org/jira/browse/SPARK-26928
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 3.0.0
Reporter: Luca Canali
This proposes to add instrumentation for the driver's JVM CPU time via the
Spark Dropwizard/Codahale metrics system. It follows directly from previous
work SPARK-25228 and shares similar motivations: it is intended as an
improvement to be used for Spark performance dashboards and monitoring
tools/instrumentation.
Additionally this proposes a new configuration parameter
`spark.metrics.cpu.time.driver.enabled` (default: false) that can be used to
turn on the new feature.
