An incident is created for an event when there is a corresponding event rule that has an action to create an incident for the event. In this situation, multiple events will generate multiple incidents. However, if the events relate to the same issue, instead of generating multiple incidents, it is better from a manageability standpoint to generate a single incident composed of multiple related events, i.e. an incident with compressed events. This is especially true if these related events are to be managed by the same administrator.

There are two types of Event Compression available in Enterprise Manager.
