[Twg] new requirement

[Felix, Evan J]

John, I just looked at his read me, it very well may do what I need, with some changes to get it to work with servers on separate networks…  It would really be better if we had a way to query directly from the server for some of the statistics over lnet, since some of the larger configs with routers and such wont have direct ssh access.  I will have to see if I can get it working.

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,
