[jira] [Created] (SPARK-25170) Add Task Metrics description to the documentation

Luca Canali created SPARK-25170:
-----------------------------------

             Summary: Add Task Metrics description to the documentation
                 Key: SPARK-25170
                 URL: https://issues.apache.org/jira/browse/SPARK-25170
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 2.3.1
            Reporter: Luca Canali


The REST API, as well as other instrumentation and tools based on the Spark ListenerBus expose the values of the Executor Task Metrics, which are quite useful for workload/ performance troubleshooting. I propose to add the list of the available Task Metrics with a short description to the monitoring documentation.
