Hi Young, You can set giraph.metrics.enable to true, and then in worker logs (stderr part) you'll see more information about each superstep. What you are interested in will be shown in requests-sent and sent-bytes, there is an equivalent for received as well.

This is for an algorithm (DMST) that sends variable size messages. In the Giraph userlogs, there are "waitAllRequests" lines which contain "MBytesSent", with statistics obtained from ByteCounter's getMetrics(). However, I'm unsure if this is right: I looked at a PageRank run, divided the reported MBytesSent by the number of outgoing messages and I get something like 0.2 bytes/message... Is it because of encoding/compression or is this simply the wrong thing to look at? Are there other counters? Thanks, Young
