Are there any tools to gauge NFS load (reads, writes, NFS ops, whatever), perhaps on a quota tree or directory level.

Why would I want to know such a thing?

Say I have an 200GB F540 filer with two large trees. And I just purchased a 200GB F630 filer. I want to move one of the trees, but not both. I want to move the busier one, not the other one.

There are some basic things I've been looking at in the above situation, but maybe someone here knows about a better method/technique/tool.

I hoping someone will mention such an obvious solution that I'll be glad I didn't mention what sort of thing I've been doing. :-)
