We are currently testing the trial of Whatsup gold ( http://www.ipswitch.com/Products/WhatsUp/ ) .. before commiting to it, does anybody know of another graphical monitor like this one ?

DeepMetrix makes a great product called IP Monitor. You can check it out at http://www.deepmetrix.com/ipmonitor/index.html

I did a project last year and compared both, IP Monitor looked to be a better product.
