Subject [jira] [Created] (GIRAPH-505) Metrics Updates
Date Wed, 06 Feb 2013 23:04:12 GMT
Nitay Joffe created GIRAPH-505:
----------------------------------

             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 locally vs. sent across
network.
3) Add some helpers like MetricNames and MeterDesc to centralize definitions of metrics used in
Giraph all in one place.
4) Better input loading metrics. Track total edges/vertices loaded and overall rate regardless
of how many threads are involved. Updates the log/status message to look like (with 10 threads)
e.g:

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

This is much clearer for the user and more informative.
