I'm currently evaluating PRTG, and so far love it.
We'd like to slap it up on its own monitor in our NOC, so we can just look up and see statuses.
We monitor almost 400 sensors currently mostly pings so far - we're about to start throwing in services, etc...
I love the "Square View" of green / red statuses - I'm wondering if there's a way to selectively put devices in there, or create different monitoring "trees" so that we could group things in our "Core" into one view and ALL the sensors in another view ?
Thanks for your work !
