Flow of Event Messages
Two types of EMS processes manage the flow of event messages from the subsystem environment to the
operations environment:
• Event Message Collectors accept event messages from subsystems and log them. Pre-log filtration (PLF) lets
a primary or alternate collector use one or more filters to detect and discard all event bursts with specified
attributes or specific unwanted events that would otherwise be sent to the collector’s log file.
• Event Message Distributors filter event messages and return selected messages to the operations
environment.
