PegaRULES.log contains application name that is defined in prlog4j2.xml as follows.

<Pattern>%d [%20.20t] [%10.10X{pegathread}] [%20.20X{tenantid}] [%20.20X{app}] (%30.30c{3}) %-5p %X{stack} %X{userid} - %m%n</Pattern>

(The "{app}" indicates application name.)

Usually the application name is output when log message is added by an operator's action like below.

However, it doesn't show application name in some other cases. For example, log message which is output in the activity invoked by File Listener doesn't show application name even though it configures Requestor Login.

Is there any condition to show or not show application name in the log? (e.g., all agents and listeners won't show application name).
