Subject [jira] [Commented] (GIRAPH-232) Add metrics system into Giraph
Date Fri, 26 Oct 2012 01:11:12 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-232?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13484635#comment-13484635

Avery Ching commented on GIRAPH-232:
------------------------------------

Adding a few comments I made offline with Nitay.

Please provide an option to dump all stats to stdout (so we can see after the fact where the
time went).

Would be really nice to have a communication time (time from first message sent until waitAllRequests
completes in finishSuperstep on the worker).

> Currently a lot of Giraph's operations are not transparent. As a Hadoop job, the Giraph
logging is at the mercy of Hadoop's logging system and can disappear when one encounters a
memory issue.
