Log File Configuration

Yes, you can totally generate your own custom report using the Text Writer or AttributeFileWriter, but you’ll need to collect the data you want manually within your workspace.

That means:

• Counting features in your input file,
• Getting the number of features written (for example, right after a FeatureWriter),
• Summing up the values of your amount fields in both input and output streams,
• And generating your own timestamp using a DateTimeStamper.

Regarding the user who ran the workspace: I don’t think you can get that directly in FME Form. But if you're running the workspace in FME Flow, you might be able to use system parameters like $(FME_SECURITY_USER) or $(FME_SERVER_RUNTIME_USER) to include that info.

For the log file name:
You can make FME generate a unique log file for each run by enabling “Include Datetime” in Log File options under Workspace Parameters > Logging > Log File.

Hope this helps!
