LAN Traffic monitoring

[sunhux G]

I'm looking for a way to monitor the traffic load, ie rate of traffic going
in
& out of a specific NIC on my RHES 4.6.

Thought of using a script to take consecutive readings, say every 5
seconds by taking the difference in the RX & TX readings & then
divided by 5 to get the rate.

Which of the following outputs are most up-to-date & accurate :
ifconfig bond0 (ie issue this command 5 secs apart, get the difference
& divide by 5)
netstat -i bond0 (ie issue this command 5 secs apart, get the difference
& divide by 5)
OR
cat /proc/net/dev


"ethtool -S bond0" on my server gave "no statistics available".


If anyone has a script (Shell or Perl) to share, appreciate if you can
email it over

Try Iptraf, I don't think it has any dependencies and I use a lot for
RHEL4.8

Hi,

I use jperf. Is a client-server aplication and it works fine when you want
to measure the traffic between 2 machines you can acces.

HTH,

Hi. For reel-time monitoring I use ipftaf. For a long-term solution I use
Cacti. It records everything to a database and draws a nice graph for you.
You can monitor your whole network with Cacti from one computer because it
uses snmp toe gather data

does iptraf or cacti outputs the results in plain text files?

Reason is I need to tabulate the data in Excel.

I found iptraf, nettop & nethog output to sort of GUI/graphical
outputs (even if I used "script filename, run iptraf/nettop/nethog,
exit") & the outputs are not in plain text file


Thanks & Merry X'mas

Hi, I'm not sure about text output, but I think you'll be able to get text
output using netstat

Have a great new year!

Zabbix can get your real time data in graph

I too suggest zabbix, an enterprise class monitoring too. This will serve
your requirement.
