[Twg] new requirement

[John Carrier]

Evan,

You  added the following comment to our google requirements doc:

"It would be very useful for me as an admin to be able to easily localize who is using my IO. Even pointing to a specific set of nodes that are doing a lot of IO 'right now' would be very helpful."

I think this is a new requirement for us.  John Hammond's lltop (https://github.com/jhammond/lltop) provides a job-by-job accounting of file system load.  Have you tried it?  If it doesn't do what you want, could you help describe your requirement?
Thanks,

--jc
