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

             Summary: Add more metrics
                 Key: GIRAPH-985
                 URL: https://issues.apache.org/jira/browse/GIRAPH-985
             Project: Giraph
          Issue Type: Improvement
            Reporter: Maja Kabiljo
            Assignee: Maja Kabiljo


When limit number of open requests is on, significant part of computation can be spent in
just waiting. So adding metrics for total amount of time compute threads spent in waiting
on open requests, and histogram with compute times per partition. These should help detecting
why some job is slower than expected (is it from messaging or compute).
