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