When somebody is hammering on the system, I want to be able to detect who's doing it, and hopefully even what they're doing.
I can't seem to find any way to do that. Any suggestions? Everything I can find ... iostat, nfsstat, etc ... AFAIK, just show me performance statistics and so forth. I'm looking for something more granular. Either *who* the activity belongs to, or *what* files are active (which might indirectly let me figure out who) ... etc. If it makes the problem any easier (or harder) all the access is coming across NFS. And maybe a little CIFS.
