Events & Alarms

Mango's event system is how the platform monitors data for abnormal conditions and takes action when those conditions occur. The event system has two main components:

  • Event Detectors -- Rules attached to data points (or other sources) that evaluate incoming values against configured conditions. When a condition is met, the detector raises an event.
  • Event Handlers -- Actions that execute in response to events. Handlers can send email notifications, execute scripts, set point values, or trigger external processes.

Events have an alarm level that determines their severity and how they appear in the alarm table. The available alarm levels, from lowest to highest severity, are: None, Information, Important, Warning, Urgent, Critical, and Life Safety.
