Hello:
I have a server with 2 HBAs, and the users keeps complaining about
performance problems. My question is, how can I relate the process
with high I/O wait? Also, is it possible to see how much data is being
pushed thru by my 2 HBAs?
iostat (part of the sysstat package) will answer your 2nd question.
I dunno how to measure io wait time per process. maybe IBM's NMON can
do that, not sure, I haven't used it for a while.
