# Alert timeline

The alert timeline shows the full lifecycle of an alert from the alert details page, so you can understand exactly what happened — like why an alert didn't create an incident, or whether it was grouped into other incidents.

The timeline includes details such as:

* When the alert fired
* When the alert resolved
* What incident it created
* What incident(s) it was marked unrelated to
* What incident(s) it was grouped into
