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!

I did that, but it doesn't seem to be working as expected. Do you have any other tips?

I put the following in the logfile parameter box:

and it produces a Logfile in the right folder, but when it comes to the name it simply put: $(FME_MF_NAME).log 

any ideas?

Hi ​@m_arc_o This works for me with FME 2024.2 and 2025.2 beta. Please submit a ticket via https://support.safe.com/hc/en-us/p/Support with more details about your situation.

Thank you ​@DanAtSafe . I’m working with Version 2024.1.2.0 (20240830 - Build 24622 - WIN64). I will try to get an update, mayby it works. If not I will submit a Ticket. 

​@DanAtSafe you were right. It seems to be a bug in our version 2024.1. I tried with version 2025.1 and it worked perfect.
