network monitor

I have used many monitoring tools I need a good free graphic network monitor tool like whats up gold anyone knwo a good one?

What platform?

W2k has a network monitor. You can also get Ethereal for windows and Unix.

If you want really graphic, I like Observer from Network Instruments, but it is a little expensive.

Not sure what your criteria is.

I am looking for something like whats up that shows graphics of servers and routers

I think he's talking about a network monitor not a protocol analyser. Ethereal and Microsofts NetMon are analysers.

Do you just need a tool that occasionally pings the server and shows you whether its up or down ? There are many little utils that do that. On the other hand if you want something that lets you use SNMP and change configuration.. i don't think you'll get a free one... unless you use linux.


Cheers

i would like to obtain something like netcrunch or whats up gold that shows a graphical map of the network

Well I happened to just look for a few network management/monitoring tools with all the buzz and whistles on it, and I think I have found one that might be worth trying, but its not free However you can still grab an evaluation license.

The name is AdventNet ManageEngineTM OpManager and the screen shots look quite sexy

I'm also just about to check out netcrunch, haven't heard of it before. I'll let you know what my opinion is.
