High CPU usage WMI memory monitoring

See more:

VB

Currently I am monitoring Memory and CPU usage using WMI. I can also detect when a new process is started by using wqlEventQuery __InstanceCreationEvent Event, along with managementeventwatcher.

Is it possible to poll CPU and Memory Usage using something similar to the instancecreationevent and managementeventwatcher and raise a event when the Memory or CPU values change?

I believe taking this approach if possible will be more cpu friendly then running the wmi query constantly.

I would usually post code showing what i have tried but honestly I am lost and need a pointer in the right direction or some information to get me started.

Thank you in advance!

What I have tried:

Public Shared Sub Process_Monitor_Start()
       Dim colMonitorProcess As WqlEventQuery = New WqlEventQuery("__InstanceCreationEvent", New TimeSpan(0, 0, 0, 1), "TargetInstance isa ""Win32_Process""")
       proc_watcher = New ManagementEventWatcher(colMonitorProcess)
       AddHandler proc_watcher.EventArrived, AddressOf Process_started
       proc_watcher.Start()
   End Sub
