Notification rules and PI Notifications Service

Notification rules: Definition and scope

Notifications is included as a feature of PI Server, starting with the 2016 R2 version, and is not installed as a separate product. The notifications feature allows you to configure "notification rules" to send email messages or to call a web service; you can also configure message content and set up escalations.

Note: Notifications created using PI Notifications 2012 or earlier are henceforth referred to as "legacy notifications".

Notifications are alerts that are generated when an event of interest is detected in the PI Server; such events are detected by examining and comparing real-time and static data with user-defined conditions configured in the PI Server. User-specified information can be configured in notifications that are sent to users or groups in real time to alert users of conditions to which they may need to respond. Notifications integrate with, and leverage, PI AF and other PI System services, and can be shared, managed, and maintained enterprise-wide. All notification actions, such as notification send times, acknowledgments, entry of comments, and escalations, are stored for later retrieval and examination.

Notification rules are based on event frames and notification messages can include information from event frame templates. For more information, see Notifications and event frames.

PI Notifications Service

PI Notifications Service is a Windows service that evaluates notification rules, processes incoming real-time event frames, and sends notifications. The PI Notifications Service need not run on the same machine as the Data Archive, PI AF server, or the client applications.

For information on event frames, see Understand event frames in PI AF.
