What constitutes an exception event in ITIL Event Management?

In ITIL Event Management, an exception event is defined as an alert indicating that something has gone wrong or that there is a critical issue that needs immediate attention. The primary purpose of event management is to monitor and respond to various events that occur within the IT infrastructure, allowing organizations to address issues proactively before they escalate into more significant problems.

When a critical system failure occurs, it generates an exception event that requires swift investigation and resolution to minimize disruption to services. This is in contrast to other types of notifications or alerts related to normal operations, warnings about potential future problems, or reports summarizing past events, which do not inherently indicate an immediate need for action due to a failure or deviation from normal operation. Recognizing and prioritizing exception events is essential for maintaining system reliability and ensuring a prompt response to any incidents.
