If you are wanting to monitor the health of your PI Server (AF + Data Archive), I would suggest using the PI Interface for Performance Monitoring and taking a look at IT Asset Monitor Toolkit. You should also think about monitoring your interface nodes. The link I posted above also comes with an AF database and a PDF + video explaining how it works.
OK thanx for the info.
But I don't understand why Osiosoft hasn't already made a general PI monitor system build in PI AF with nice displays in PI Vision.
