PI Notifications

Configure custom alarms based on any data source by leveraging the flexibility of PI AF.


  • The generic data access and template driven capabilities of PI AF allow users to re-deploy these parameters to similar assets across the enterprise.
  • Configure the platform to emit notifications when operational excursions occur. Alerts can go to a single recipient, a group of contacts, or an escalation team, reflecting the organization's chain of command.
  • Every notification and alarm event is collected for later access during auditing, reporting, or alarm threshold tuning.
  • Configure events through a standard user interface or custom applications via the SDK.

  • Out of Band Alerting: Send notifications when an operational excursion occurs, without requiring the constant supervision of the process control environment.
  • Escalation Management: Match notification delivery to the organization’s chain of command.
  • Excursion Auditing: Report on operational excursions, notification delivery, and actions taken when the process control environment exhibits anomalous behavior.
  • Disparate Data Triggering: Bring all operational data together by leveraging the flexibility of PI AF's generic data sourcing functionality. Use this data to trigger custom alarming conditions and notifications.
  • Cross-System Messaging: Programmatically extend notification delivery to seamlessly integrate messaging to third party applications such as workflow, ERP, and asset maintenance systems.
  • On Demand Visualization: Link notifications to OSIsoft's powerful visualization tools including PI WebParts, PI ProcessBook, PI DataLink, and RtReports to provide on demand visualization of anomalous system behavior.

      Example of Product Implementation

Business Challenge

One of the largest software companies uses PI Notifications to monitor its data centers. In a business where performance is measured in terms of both uptime and energy efficiency and where the number of monitored assets grows into the hundreds of thousands, it is vital to monitor all assets and alerts by exception. Data centers are nearly unmanned environments with only few support engineers, yet they are tasked with managing massive quantities of assets and data.


Thanks to the template-based nature of both PI AF 2.0 and PI Notifications along with the powerful layer of programmatic access to the software, this company was able to achieve a high degree of automation for the PI Notifications implementation. Detailed asset models of the relationships between power distribution units, racks, and the connecting circuitry were created, and Notifications based on power usage thresholds for each circuit were implemented.

Customer Result/Benefit

Data centers spend millions for power along with millions more for backup power equipment such as generators and batteries to handle power outages and ensure uptime. Even with all this high tech equipment and contingency planning, it is vital to monitor how much power individual circuits are consuming and to configure alarms to notify users for abnormal situations. This way, a customer can be certain that all circuits within their data centers are being monitored and, while maintaining a very limited number of on-site IT professionals, they are assured that theirs centers are running optimally.
