In this activity, monitoring data from various system resources are input and converted into events. Monitoring data can be generated by a vast number of system resources. The data might be generated by a resource or by a monitor of that resource. This data is used to identify status changes to resources.

Many system resources generate monitoring data that is not indicative of a fault. This activity monitors that data in order to identify all potential events contained in the data. Events generated by this activity are also recorded. This information includes information about configuration items related to events and might be necessary for the resolution of incidents, problems, reviewing SLAs, or other service management purpose.
