------------------------------------

             Summary: monitor ingest, query, etc. rates are too smooth
                 Key: ACCUMULO-3300
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3300
             Project: Accumulo
          Issue Type: Improvement
          Components: monitor, tserver
            Reporter: Adam Fuchs


We use an exponential decay function to smooth performance monitoring. This dates back to
the early days of the project when we were taking samples frequently and everything looked
like noise. Now our performance is a bit more steady and we take samples about every 5 seconds.
I think we need to update some parameters so that finer-grained performance characteristics
show up in the monitor. This is critical for the next wave of Accumulo performance improvements.
