In ITIL v3, event management is an additional feature used to define a process that helps leverage automation to manage events to become more effective and efficient. ITIL defines an event as “any detectable or discernable occurrence that has significance for the management of the IT infrastructure or the delivery of IT service and evaluation of the impact a deviation might cause to the services.. (ITIL Service Operation book, Page 35). In event management there are three paths that can be taken:
Informational: These are events that should be logged for potential future analysis including confirming if the service is operating as expected.
Warning: During service design, thresholds are identified that help gauge the status of a system. When the threshold is reached, predefined parties, or notification groups, are alerted that the threshold has been reached.
Exception: This branch is reserved for configuration items (hardware, software or service) that are operating abnormally or have failed. Abnormal behavior criteria should be defined during service design to better understand what types of scenarios trigger what types of exception handling.

A condition, often an error, that causes the program or microprocessor to branch to a different routine. The terms interrupt and exception are very close in meaning. Both can be used to refer to either hardware or software. The only real difference is that an exception usually indicates an error condition.
- exclusive OR
A Boolean operator that returns a value of TRUE only if both its operands have different values. Contrast with the inclusive OR operator, which returns a value of TRUE if either of its operands is TRUE. Whereas an inclusive OR can be translated “this, that, or both,” an exclusive OR means “this or that, but […]
