Alerts occur when an event triggers an action. You can add actions and triggers in the** Alerts** module that can use events to send notifications.

Review [Alerts Guides](docId\:Z6I7f1kbZSHNsn6FZliSe) to learn more about setting up alert triggers.

The Alerts module includes three sections. 

# Incidents

The *Incidents* module includes a list of edge devices for which there is an incident. Incidents are generated alerts that are based on triggers. System triggers are preloaded, and user triggers are created in [Alerts](docId\:BWq6oBkuTNZgIJBIgQPBE).

The *Incidents* pane includes filters for selection of a group list, state, and date range filters for Opened Before, Opened After, Closed Before and Closed After.

# Triggers

The Triggers section includes user-defined triggers. A trigger uses an event or a metric to trigger an action, which in turn sends a notification. 

You can create, view and modify user-defined triggers for the actions listed. An alert occurrence is registered as an incident and is shown in the [Incidents](docId:81uhi0Waj080EuLYceOaf) module. The generated alert appears in the [LEM Dashboard](docId\:NICP2iziO86MTz4iqR5DP) module and the [Events](docId\:Qh9PnCUT-G1k_Lz9p4-m3) tab in *Edge Device Details*.  

**Alert Options**:

- Email
- Webhook
- Slack
- Pagerduty

# Notification Settings

From the *Notification Settings* section, you can add, modify, and view actions that is used by a trigger. The action sends a notification (Email, Slack, Webhook, Pagerduty) when a trigger is applied.
