# Alert lifecycle configuration

# Alert lifecycle configuration {#ariaid-title1}

Event Management provides
various modules, templates, and properties for configuring alerts and the actions that
execute for these alerts.
* **[Configure the alert active interval](https://servicenow-prod.fluidtopics.net/MXm7ZQDJ2r9hED90QaGL9A)**   
  The active interval property (evt_mgmt.active_interval) determines how Event Management handles a new event that is similar to events that appear on an existing closed alert. Based on the active interval, event, and existing closed alert information, the alert is reopened and the event information is added to the existing alert or a new alert is created.
* **[Configure alert flapping](https://servicenow-prod.fluidtopics.net/e8HTvciLULJkL2tY96KBYA)**   
  Set flapping properties to determine when an alert enters and exits the flapping state. Flapping can indicate configuration problems (that is, thresholds set too low), troublesome services, or real network problems.
