Bandwith Utilization Tool

[zTargeTz]

Need to check the bandwith on my network, are there any tools that can will graph this out for me? doesnt even need to do that,i can punch numbers into excel.. just need something that can track the bandwith usage at various points around my netwwork so i can figure out where the bottlenecks are

Thanks

any free ware, or some demo stuff i could try out?
i dont mind buying if it works good..

btw my network supports 550 users with 59 network "devices" all cisco tied together with 1gb back bone on fiber

Sorry. I did not see your second post while I was typing the answer to the first one (notice the few minutes difference).

May be you can find something here: http://www.networkingfiles.com/Monitor/monitor3.htm

The whole idea of a switch is to isolate traffic so that it's only seen by the sender and receiver and nothing else. This means there really isn't a way to capture traffic statistics with any kind of network probe. The only real method is by using a SNMP tool that can go out and poll the switches and their individual switch ports for traffic in/out. (Unless you want to spend the cash for RMON agents on the switches and a RMON software collector - Big $$$!).

I'd give MRTG a try. It's a pretty slick tool to get traffic statistics on devices. It was designed for routers, but I'll bet that configmaker will discover switch ports if you aim it at the SC0 management address of each switch and have SNMP properly configured.

MRTG good.

 

[zTargeTz]

I'll give MRTG a try & let you know how it works out

Hmm, need Perl to run it

 

[zTargeTz]

I've never used perl before so im struggling with the instalation of MRTG, hopfuly it will all come together soo

Im going to get a box and load linux tomrrow, then install that way ( i hear its easyer than Windows anyway)
some one said that some distro's of linux come WITH MRTG so hopfuly it will be like that for me
my grasp on linux is fairly limited, I might end up PM'n you tomrrow (if i can figure out how to PM onthis board.. lol )
thanks

hmmm...mrtg is good, but RRDtool is much better.

Gads! MRTG...YUCK! Sorry. No offense, but honestly...YUCK!

Why? The config file sucks, for one. It can't capture errors for another, amongst other things it can't measure. Not a fan...as you can tell.

Cricket is much more to my liking. Easier to configure and can capture much more meaningful information. Measures usage in octects!

Again, just my .02 on this one though.Cricket

Damaged, you are the first person I have ever heard say that MRTG was bad. The only thing I've ever heard negative about MRTG is that someone things that some other tool is better. And that may be. But MRTG has always been the just-works tool for the job IMO. Special requirements may drive the need for some other tool instead, but 95% of folks are well served by MRTG.

Granted, the config & index file stuff is annoying, but cfgmaker and indexmaker pretty much handle it for you as long as you're doing everyday stuff. If you have some routers and/or some managed switches and you want to get performance data / graphs out of 'em, MRTG is pretty simple to set up.

you've obviously never used RRDtool. Check my site here: click me!

was done using rrdtool and cacti
