Tracing levels for the Correlation Engine

The logging function in the correlation engine can be used to trace the flow of event processing in UNIX System Services. By default, the correlation engine logs only informational-level entries, which show initialization, stopping, and connection messages. By using the CORRSERV LOGLEVEL command, or by setting the logging level in the logging properties file, the log can generate entries showing the flow of events into and out of the correlation engine. A logging level of DEBUG_MIN generates entries showing the receipt and sending of events. A logging level of DEBUG_MID adds the contents of events and show entry and exit traces for the methods in the correlation engine.
