             Summary: Adding JMX Metrics for Timeline Collector and Reader
                 Key: YARN-8270
                 URL: https://issues.apache.org/jira/browse/YARN-8270
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: ATSv2, timelineserver
            Reporter: Sushil Kumar S


This Jira is for emitting JMX Metrics for ATS v2 Timeline Collector and 
Timeline Reader, basically for Timeline Collector it tries to capture success, 
failure and latencies for *putEntities* and *putEntitiesAsync*  from 
*TimelineCollectorWebService* and all the API's success, failure and latencies 
for fetching TimelineEntities from *TimelineReaderWebServices*. This would 
actually help in monitoring and measuring performance for ATSv2 at scale.
