Is there a way to write messages to the existing logs

Say I want to log an entry into the server log or one of the other logs whenever each of my FTP sessions complete successfully. How would I do that? We are running IS 6.1


Use this builtin service (pub.flow:debugLog)and set input message(set your custom message here) this entry will showup in the server.log.

Generally this service will be invoked for debugging,testing the flows.
