To reduce log file size, which method is appropriate?

• A. Use FME Options to filter log messages
• B. Increase log verbosity
• C. Write log to separate file
• D. Disable logging entirely

Answer: (A)

Controlling what gets written to the log is the way to reduce its size. By using FME Options to filter log messages, you tailor exactly which messages are recorded—for example, you can keep only warnings and errors or only messages from certain components. This trims the log to the essential information you need, without turning off logging entirely. Increasing verbosity would do the opposite and make the file larger, while writing the log to a separate file or disabling logging entirely either relocates data or eliminates useful diagnostics. So filtering log messages in FME Options is the most effective approach to reduce log file size.
