I found a sudden increase of network load in my machine which is 4 times more than normal through the perfview.
I haven't add any application newly to my system.When I see through perfview there are no error packets or no congestion in the network.
I would like to know who are the user consuming how much bandwidth of the network and by processwise also which will enable me to idenify the problem.
So suggest some utility to find process,user based network bandwidth consumption or any HP-UX command which gives the network usage by processwise or userwise.
Solved! Go to Solution.

SolutionI don't think there is an easy way to do this. You will need to have:
1) a traffic monitor/sniffer tool
2) a port -> user matching tool
3) a script to integrate 1) and 2) and monitor over time
For 1), you can use ethereal (easiest to use) or tcpdump or as a last resort, HP-UX's native nettl. Measure the bytes transfer at specific time to specific service ports.
For 2), use lsof to monitor the owners of each socket opened on the server at specific times. You have to run lsof at periodic intervals as it only catches current state of sockets.
For 3), you will need to write a script. Either that or you have to perform the matching process manually.
Hope this helps. Regards.

Re: Network load monitoring
This won't give you the smoking gun, but it usually points you in the right direction and does have the advantage of not having to install new software.
