Programmatically Check Process CPU Percentage

I'm attempting to write an app that watching for process spikes. IE: Watch every active process and log the difference between initial and max values of cpu percentage (or load) of each process. The problem is that, as far as I can tell from the MSDN, the Process class doesn't contain any property that is even remotely equal to the true load of the process. For the time being I've written the code to watch the PagedMemorySize64 property, but the values that are being spit out appear to have no relevance to load.

To be clear, I don't need the actual load percentage (though it would be handy), all I need is a property that is directly related to load to show what processes 'spike' during the execution of my program.

My code as it stands (initialProcessCheck runs first, then processCheck runs every 1.5 seconds or so until other threads doing irrelavent tasks are finished, then computeDeltas is run):

Private Sub initialProcessCheck()
'Checks the current load on all active processes and stores as initial values
For Each intPID As Integer In ActiveProcessIDs
Dim CheckProcess As Process = Process.GetProcessById(intPID)

[Code]....
