Hi..

What would be the best tool (either AIX or 3rd party) to monitor and
reoslve network thruput issues on your AIX environment (assuming you
have a bunch of p595's)

Thanks

try iperf : http://dast.nlanr.net/Projects/Iperf/
it is open source, compiles and works fine on AIX.

Did you just download the SOURCE and compile w/ GCC?

thanks!

My knowledge of iperf is a bit rusty, but IIRC tools like iperf (and
netperf

are useful, but they aren't monitors, they are active
benchmarks.

netcat and nmon with the "n" subcommand.

set up a listener on one system, then on the other dd /dev/zero thro
netcat to the listener .. this will give you throput visible from nmon.

Thats the way I do it anyways .. you could also check out iptraf ..

ttcp and iperf are similar, and also works in a client/server mode.

(Just mentioning.)

Am I missing something or isn't that what ftp was invented for? 8-)

Actually, I used to keep a compiled lukemftp around a lab because it
gives instantaneous feedback.

We all know that FTP is a _system_ benchmark not just a networking
benchmark

Those pesky discs and filesystems...

system, how can i pull out
the info from the other AIX servers?

Netcat is a nuts and bolts shell networking tool. It is low footprint
and is much more efficient and adaptable than something like ftp for
looking at network throughput. So if you want pure network throughput
without writing your own socks app, then netcat is your tool.

http://aixpdslib.seas.ucla.edu/packages/netcat.html

On one node do this ..

netcat -l -p 9999 > /dev/null 2>&1

And on the other node do this ..

dd if=/dev/zero bs=4096 count=1024000 | netcat hostname_of_other_node
9999

Then look at nmon with the "n" sub command on both nodes.

You can obviously play with block sizes and counts as you see fit.

dd'ing from /dev/zero and then into /dev/null rules out any disk i/o
subsystem.
