> Project: Apache Trafodion
> Issue Type: Improvement
> Components: sql-general
> Affects Versions: 2.1-incubating
> Reporter: Selvaganesan Govindarajan
> Assignee: Selvaganesan Govindarajan

> Improve RMS to provide the following features/capabilities:
> 1. Currently RMS can list queries that consumed cpu time between two time points. However, the calls to storage engine like hbase, hdfs etc are blocking and these blocked APIs will not allow the Trafodion SQL engine scheduler to detect the cpu time spent during the time the call was blocked. Introduce a feature called SE offender (storage engine offender) to list the queries that are blocked in storage engine more than a certain duration.
> 2. Remove counters that are no longer updated or needed
