Relation between processes and network activity

Andreas Poeschl — Fri, 03 May 2002 11:01:41 GMT

Hi,

is there a possibility to see, which process on a machine causes network load?
The problem is that there are lots of processes running on a machine (HP-UX 11.11), which generates quite a lot of unexpected network activity.
I am thinking of a kind of extra '%NET' column for 'ps' or a tool to record network activity for a special process.

Thanks in advance,
Andreas

Andreas,

I'm quoting from the HP-UX Performance and Tuning course:

"Although the symptoms of network bottlenecks are readily apparent, the bottlenecks are very hard to trace without a tool like HP OpenView Network Node Manager. One large consumer of the network resource is the rwho command.
Hp GlancePlus/UX reports on network traffic as well as NFS reads and writes and diskless traffic."

Hi,

well the two tools being able to do that are:
- GlancePlus (glance/gpm)
and
- MWA (MeasureWare Agent, today OVPA = OpenView Performance Agent)

HTH,
Wodisch

If you have Measureware, you can use some indirect methods to find out the procs that are waiting for Network. Look at the following thread.

Andrea,

If you have meassure ware installed then please configure the file parm. in /var/opt/perf where you can specify specific process which needs to be monitored for resource utilization. A detailed example of how this can be done is in /opt/perf/newconfig/parm.examples .
Once the above is done pleas use the commands "utility" or "extract" depending on how you eant the data. You may also use perf view in case you have it.

Thanks
