Hey , guys
i am looking for a good traffic monitor tool for my network that is easy to use.

I have tried a tool names mrtg,it shows the traffic with in and out on interfaces with speed ,but it can just count the traffic for last 24 hours or 1 month or 1 year , even 24 hours is too long for me ,because the traffic that I make in my network lasts just 5 mins. therefore the results it shows on a 24 hour-scale so small because of only 5 mins on 24 hours. and I can not chage the scale smaller. I just need a traffic tool that can count the traffic in last 5 mins ,maybe 10 mins with realtime.but not 24 hours or 1 month.

Help me please!

hmm i just migrated to redhat shrike nine got it from here

http://www.linuxiso.org/distro.php?distro=7

first time ive used it but the system monitor can be set to run in taskbar

it will include swap file,memory,cpu and network and each one has different displays like idle, ethernet load etc etc

AND it updates every 5oo milliseconds surely that would be sufficient??

ethereal is extremely useful as a open source product
we use it at work all the time, its a packet sniffer
what exactly are you looking to do?

hi, upstairs
thanks .what I excatly want to do is:
I just want to test my firewall with Traffic Control(HTB) . I want to know how well my skript works,so I need to know the real bandwidth for in and out on interfaces with graphic and text output,when I transfer Data from one to another,for instance download while uplink-(in and outrate).
Ethereal I have installed.It is good ,but not suits my status.By Ehereal we can get the IO GRAPH , but the result is the sum from in and out, I need each graph of the two.

please help!

Hi,

Can someone spare a mrtg howto? I failed to configure it and I also need to monitor my network bandwidth on my proxy

Have you taken a look at routers2.cgi ? It's a frontend display tool for mrtg. What I really like is the "rescale" button for graphs that have low throughput on a 100MB link. Routers2.cgi does require a web server that is capable of running cgi scripts and you will have to convert mrtg to using rrdtool instead of generating graphs. FWIW: It was worth the time converting to rrdtool at my end.

I just need a software that can easily monitor network traffic in realtime with graphic output,is there such sofware by linux? it is just a simple will.

You may be interested in the following tool. It's called EtherApe and provides a sort of "air traffic controller" view of your network in real time.
