             Summary: Accumulo metrics improvements
                 Key: ACCUMULO-3817
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3817
             Project: Accumulo
          Issue Type: Improvement
            Reporter: Billie Rinaldi
             Fix For: 1.8.0


I've been taking a look at the hadoop metrics2 metrics Accumulo is providing and trying to
make interesting graphs out of them.  Most of the tserver metrics are provided as avg/min/max/counts,
which might be okay for heatmaps, but aren't good for aggregating over to provide a graph
for an entire instance.  Also, most of the metrics we're using to display useful information
on the monitor page don't appear in the metrics2 collection.  The master doesn't have any
metrics at all beyond thrift and replication.
