Hi there,

My sincere apologise for this silly question, but does anybody know any
either tool,program,script, or native tool in RedHat to measure the real
network traffic on my network. I have set up a COW (8 nodes) and I am using
MPICH 1.1.2 to run a parallel program. When I run above program the network
traffic is very high so I just wonder if it could be a bottleneck.

I have used netperf and the latest version of SCMS which displays some
network device information too, but it does not really help me much.

Any ideas?
I would really appreciate any information.

Thank you very much.
Sincerely Yours,
