Subject Re: Accumulo Ingest JMX metric

Yeah, this looks wrong.

The numbers the monitor gets are from the TabletServer polling each Tablet

https://github.com/apache/accumulo/blob/1.6/server/tserver/src/main/java/org/apache/accumulo/tserver/TabletServer.java#L3676-L3677

The JMX metrics reported by the TServer should also likely do the same.

Care to file a JIRA issue?
