Measuring network load for protocol and destination specific

[Ramesh Donti]

Hi,
I have 10 HP-UX systems in a subnet. I want to measure the network traffic( in Bits/Bytes) between these systems.

Eg: ftp transfers from system#1 to system#2 and smtp traffic between system#1 and system#3 etc..

Is there any shareware available.

I will summarize

start with big brother. Gives you more than just network monitoring.

www.bigbrother.com

or
a number of network montiroing tools at

If you want Big Brother (one of the better ones) here is the correct link:

You could also browse the HP porting centre.....

Hi,

whar you really need is an RMON (or even better RMON2) agent running on the hub/bridge/switch connecting those stations.
RMON keeps track of the traffic 30s and 5m intervalls, like "top-talkers", and "top-listeners", and who talked to whom with which protocol (maybe you already have one there?).

To understand the data measured you will need an RMON/RMON2 manager, of course...

Just my $0.02,
Wodisch

If you have access to your routers you can use ip-accounting on the serial interfaces that connect your networks

en
conf t
int s(?)
ip accounting

You will then be able to see the packets in and out between the 2 servers, not sure if you can distinguish the type of traffic though unless you can see the port numbers, ie ftp = 21 and smtp = 25. Our network guys have left for the day. I can ask tomorrow and get back to you

or

Ask Mr Klauzner i'm sure he would be able to help.
