Which action should you choose to emit a log line rather than trigger a workspace?

• A. Log a message
• B. Run a Dynamic Workspace
• C. Filter messages
• D. Merge messages

Answer: (A)

Emitting a log line comes from explicitly writing a message to the log. The action that does this is the one labeled to log a message, which writes your text (and severity) to the FME log without starting any other workspace. This is exactly what you want when you need a trace or diagnostic line in the log.

The other options operate differently: triggering a workspace would start another FME workflow, not merely record a line in the log; filtering messages changes which messages get shown or saved, but doesn’t create a new log entry on demand; merging messages combines message streams rather than producing a standalone log line.
