Subject Re: [nodetool] repair with vNodes
Date Sun, 17 Feb 2013 17:31:47 GMT
I'm a bit late, but for reference. 

Repair runs in two stages, first differences are detected. You an monitor the validation compaction
with nodetool compactionstats. 

Then the differences are streamed between the nodes, you can monitor that with nodetool netstats.

from the logs or JMX.
Grep for "session completed"
