             Summary: Metrics Updates
                 Key: GIRAPH-505
                 URL: https://issues.apache.org/jira/browse/GIRAPH-505
             Project: Giraph
          Issue Type: Bug
            Reporter: Nitay Joffe
            Assignee: Nitay Joffe


This patch adds the following:

1) Per-superstep, per-request-type counters. For example a counter for how =
many "SendPartitionMutationRequest" messages are sent.
2) Per-superstep counters and gauges for how many requests are handled loca=
lly vs. sent across network.
3) Add some helpers like MetricNames and MeterDesc to centralize definition=
s of metrics used=C2=A0in Giraph all in one place.
4) Better input loading metrics. Track total edges/vertices loaded and over=
all rate regardless of how many threads are involved. Updates the log/statu=
s message to look like (with 10 threads) e.g:

readEdgeInputSplit: Loaded 619000000 edges at 3578098.2516499613 edges/sec =
Memory (free/total/max) =3D 61174.90400695801M/120832.0M/120832.0M=20

This is much clearer for the user and more informative.
