= Receiving Cache and Cache Manager Events
You can use CDI Events to receive Cache and Cache Manager level events.

* Use the `@Observes` annotation as in the following example:

[source,java]
----
import javax.enterprise.event.Observes;
import org.infinispan.notifications.cachemanagerlistener.event.CacheStartedEvent;
import org.infinispan.notifications.cachelistener.event.*;

public class GreetingService {

    // Cache level events
    private void entryRemovedFromCache(@Observes CacheEntryCreatedEvent event) {
        ...
    }

    // Cache manager level events
    private void cacheStarted(@Observes CacheStartedEvent event) {
        ...
    }
}
