Lustre discuss - Nov 2012 - Monitoring program io usage

We run a small cluster with a two node lustre setup, so its easy to
see when some program thrashes the file system. Not being a
programmer, what tools or methods could I use to monitor and log data
to help the developer regarding their io usage on lustre?

Hi David,

I periodically update a wiki page with third-party tools for Lustre:

Given your requirements, I would suggest having a look at xltop. Or
maybe lltop.

cheers,
Richard
