Event Management Service (EMS)
Communications subsystems that support DSM report events (abnormal or significant
occurrences) to the Event Management Service (EMS). EMS provides a way for
subsystems to report important occurrences like hardware malfunctions, availability for
service, or the need for routine operator intervention (for instance, to put paper in a
printer or money in an ATM).
Subsystems report events to an EMS collector process, which places event
messages in a log. EMS components called distributors read the messages from the
logs and distribute them to applications, terminals, printers, or remote nodes.
Operators or applications can monitor events as they occur or review events that have
occurred in the past.
