AEP uses PI infrastructure to monitoring IT assets. AEP has identified several initial difficulties in using PI in IT monitoring: lack of relational structure in time series data, difficulty in maintaining manual visuals and lack of event management. With PI AF and PI Notifications, AEP has overcome those initial difficulties. PI AF adds relational meta data on top of time series data and PI AF template reduces data management efforts. PI Notifications add event manager with template based trigger events.
