An event instance is an instance of an event type. It identifies a running event type for a given schema, event type, agent host and target_host.
The number if instances in usm_event_instance at a give point in time identifies the number of running data collections/measurements. An event instance is similar to a data collection in slm 3.5.
One event instance can be used by multiple metric instances to produce the metric result. A event instance has an associated set of attributes, which is identified by the usm_event_instance_value table.
