network monitoring software

[AkshayModak]

Hey Can any one suggest me a cheaper and  EFFICIENT network monitoring software for large scale network.?

[Nicolas Darchis]

I think this question has nothing to do in the wireless community does it ?

This community is "security and network management in wireless".

You are in the wrong zone my friend, however I will still recommend. Try PRTG, its cheap and suitable for large scale networks.
