Network throughput

Prashant Zanwar_4 — Wed, 15 Dec 2004 11:39:44 GMT

I RUN REDHAT LINUX Enterprise edition. I dont have much ideas, so keep digging time to time about something to do!

I want to know network performance of my host. Are there any tools on Linux for this..what will be the best way!
Thanks
Prashant

Hi Prashant,

what you mean about network performance ?

You want to know about colisions, errors ? You want to know about nic configuration ?

Well,
#ifconfig -a will report to you colisions, errors and a lot of other informations.

#ethtool ethn
will display and configure nic configuration.

You may use netstat also. This utility has a lot of functions that you may see at the man page.
#man netstat

Regards,
Xyko

I guess he is looking for something graphical.

Take a look at netwatch. You have to download and install it, though. Here is what the first line of man page says about it:
Netwatch examines all the packets travelling on an ethernet and analyses the IP packets.

I want to count on the network traffic overall...Like snoop and other stuff..like glance does..
Is there something available on LINUX which can give me data on this!

"netperf" is probably the tool you want.
See
http://www.netperf.org/

Link to the binaries for linux are available at the
above website.

Hi Prashant,

I went to look a litle bit about snoop and I guess tcpdump has a similar function.

I think "netstat -i" will give part of you want about nic statistics.

netperf will generate traffic but only measure what it generates
