networking tool like ntop

[Andrea_66]

Hello Guys,
does anyone knows if there is tool that checks in real time network connections bandwidth (KB/S)?
ex.
172.30.223.150:4338->172.30.223.152:1526| 3KBs
I tried Ntop but I wasn't able to install it in HP-UX 11.11 -
Any help would be appreciated.
Thank you, bye,
Andrew

Hi Andrew,

Look at Netperf.

Hi Andrew,

Try this,

http://hpux.connect.org.uk/hppd/hpux/Networking/Admin/sntop-1.4.2/

you may have to recompile the source code for 11i if the 11.0 version does not work.

Hope this helps.

And there is also ttcp wich is a lightweight program freely available...
I got a copy from http://ftp.arl.mil/ftp/pub/ttcp

All the best

Thank you for the replies, I'll try those solutions and reply!
I've already tried Netperf and it doesn't seem to be compliant with what i'm looking for, anyway i'll try it again.
Stay in tune, please
Bye

Some news:
I tried Netperf and Ttcp, but they require an additional installation on the remote machine I want to monitor. Unfortunately I can't perform this installation, because I don't have access on that machine.
For Sntop, instead, i didn't find the information i need (the bandwidth in KB/S), maybe because i can't use it! Any suggestion??
Thanks
Goodbye

Hi again,
I just tested ttcp, there is depending what you want no need to have it on the remote box:
on draco (remote box)=>
# find / -name ttcp -print
/usr/dt/bin/ttcp #This is NOT the program...

# ./ttcp -t -p9 -n100000 -s draco
ttcp-t: nbuf=100000, buflen=1024, port=9
ttcp-t: socket
ttcp-t: connect
ttcp-t: 0.1user 0.9sys 0:09real 11% 0i+59d 29maxrss 0+0pf 3760+103csw
ttcp-t: 102400000 bytes in 1.040000 CPU seconds = 96153.846154 KB/cpu sec
ttcp-t: 102400000 bytes in 9.094533 real seconds = 10995.616817 KB/sec
octant # pwd
/sm/export/hpux/admin

You need to compile it thought...

All the best
Victor

Hi Andrew,

This may be too much for what you are trying to do.

The product ethereal has the capability to show the bandwidth for that moment. It cannot be used to continuously capture the data. It can be painful to install this tool. It's available at the same site.

If you need to continuously capture the data, then you will need to use measureware. You can capture the IN_BYTE and OUT_BYTE metrics per interface and arrive at the bandwidth usage. Even with SNMP (snmpget) you can capture the data.

As much as I like to promote netperf :) indeed it is not suited as a monitoring tool. Netperf is a benchmark, not a monitor. Ttcp is similar.

Glance has some network statistics in it, although they are not per-connection.

IIRC, the only way to get per-connection statistics is to use packet tracing. Perhaps that is what ntop does. If so, the overhead may be rather substatial
