What are the three types of events in ITIL Event Management?

In ITIL Event Management, the three types of events are categorized as informational, warning, and exception events.

Informational events are those that indicate a normal operation or status. They provide details about the system or service functioning without suggesting any immediate need for action. For instance, a log file entry indicating successful processing can be considered an informational event.

Warning events, on the other hand, signify that a potential issue may arise if no action is taken. They serve as a proactive notification to alert the IT staff that a certain threshold has been reached or a condition is not ideal, suggesting that attention may be required to prevent a disruption.

Exception events denote an anomaly where an unexpected or undesirable outcome has occurred. These events typically require immediate attention and often lead to incident management processes to address the disruption they represent.

This classification helps organizations respond appropriately based on the nature of the events, ensuring that resources are allocated effectively to maintain optimal IT services.
