# Events

Configure event channels and sinks in GridGain 9 to track and deliver cluster events, and browse the full list of available event types.

GridGain can generate events for a variety of operations happening in the cluster and notify your application about those operations. There are many types of events, including cache events, node discovery events, distributed task execution events, and many more.

* [Working with Events](/docs/gridgain/gridgain-9/gridgain9-development/messaging-and-events/events/working-with-events.md) — enable events, configure event channels and sinks, and understand the event structure.
* [Available Events](/docs/gridgain/gridgain-9/gridgain9-development/messaging-and-events/events/available-events.md) — the full reference of event types and their fields.
