WMI monitor in IIS 8.5?

I'm trying to configure the WMI monitor on Windows Server 2012 R2, which is IIS 8.5.

I used the instructions for IIS 7.0. URL https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm-basics-11-6-0/8.html?sr=53401315, section "Installing the Data Gathering Agent F5.IsHandler.dll on an IIS 7.0 server".

I found that there were a number of options that appeared to be new, and I was unsure how to set. However, I took the defaults. When I got it configured and turned on, it failed. I got these events in the event log:

Exception information: 
   Exception type: TypeInitializationException 
   Exception message: The type initializer for 'F5.PseudoCPU' threw an exception.
   at F5.PseudoCPU.getInstance()
   at F5.IsHandler..ctor()

Object reference not set to an instance of an object.
   at F5.PseudoCPU..ctor()
   at F5.PseudoCPU..cctor()

Is there any good way of debugging this? Are the proper app pool and site settings documented for IIS 8.5?
