I created a flat array. I thought it is easier to extend, but I can change the format. Each top level entry has a type property, describing the info in the literal:

machineInfo: information about the machine
machineState: information about the current machine state (it contains a cpuLoad property which is the percentage load of the machine
topProcess: a top process in terms of CPU consumption. Must not necessarily be a code process or one of its sub processes.
processInfo: a code process or one of its sub processes.

Both topProcess and processInfo have a cpuLoad property. The property is an array. Each element is a % load value computed for 1 second. By default the script does 10 such samples. This gives an indication if the process is for example in an endless loop if these values are constant.

Let me know if you need more information. I can basically add whatever is necessary now that I understand how to do this in PowerShell. As said I can also change the format.

Side note: I fought quite some time with hashtables in PowerShell. The key is type and if for example the key value you use is a double and the you try hashtable[4] you get nothing. You need to do hashtable[[double]4] :-). Although PowerShell doesn't really type everything needs to have a type and there is no auto conversion
