Subject [jira] Updated: (CASSANDRA-1489) Expose progress made on PendingStreams through JMX
Date Fri, 10 Sep 2010 21:51:35 GMT

Nick Bailey updated CASSANDRA-1489:
-----------------------------------

    Attachment: 0001-Progress-added-to-incoming-streams.patch
                0002-Progess-added-to-outgoing-streams.patch
                0003-Moved-FileStreamTask-to-streaming.patch

I think this pretty much accomplishes what you want. The output is similar to:

> So I thought originally that the pairs of numbers shown after filenames returned from
org.apache.cassandra.service:type=StreamingService's getOutgoingFiles/getIncomingFiles calls
were (octetsSent, totalSizeInOctets).  Now I know that they are ranges, and that there can
be several of them with one file, and that makes sense, but there doesn't seem to be any way
to query the progress made on a PendingFile stream.
> We would very much like to be able to inspect that from the outside, in whatever way
makes sense.
