M4300 Series - NMS300 EOL ideas

Hello,

I currently have a medium size network that runs offline (no WAN) and I use NMS300 for a Overview/ Management/ Statistics.

I have seen that this product is marked for End-Of-Life. I cannot utilise WAN/Internet facing applications and would like to use a Netgear product to carry on doing this. Due to it going EOL, I would like to see what other people might be using anyway or would suggest in my scenario.

I have seen some stuff on the 'Engage Controller' but not yet tested. I can see its use for configuration and a overall page to view switches.. but does this offer the same in depth statistics (CPU/RAM/Port Info etc)?

Or is there another offline tool which I am not aware of?

Thanks for the help.
