Q6930030: It is possible to monitor Hyper-V Dynamic Memory through ActiveXperts Network Monitor?

There is no built-in Hyper-V Dynamic Memory check in Network Monitor.

However, it is very well possible to monitor Hyper-V Dynamic Memory performance counters through our Performance Counter check. There's a good article on these counters here:
