The scope of ITIL (the "Information Technology Infrastructure Library") is larger than that of integrated management. However, event correlation in ITIL is quite similar to event correlation in integrated management. In the ITIL version 2 framework, event correlation spans three processes: Incident Management, Problem Management and Service Level Management. In the ITIL version 3 framework, event correlation takes place in the Event Management process. The event correlator is called a "correlation engine".
