> 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.
