# 4 Events

#### Overview

Events in Zabbix are generated by three sources:

-   triggers - whenever a trigger changes its status
-   discovery - upon detection of hosts or services
-   auto registration - when active agents are auto-registered by server

Events are time-stamped and can be the basis of actions such as sending
notification e-mail etc.

To view details of events in the frontend, go to *Monitoring* |
*Events*. There you can click on the event date and time to view details
of an event.

More information is available on [each event
source](/manual/config/events/sources).
