Log_Filename Field Extracted as 'unknown' and 'Show Top Values' Not Working

I’m encountering two related issues in Graylog:

  • The extracted field Log_Filename is showing the value unknown
  • When trying to use the “Show top values” action on Log_Filename, it does not display any data (no top values appear).
    I expect to see the correct extracted filename and be able to view top value statistics for analysis.

Seems something is going wrong in extracting the field. You’ll need to give us more details on how you are doing that; and trouble-shooting you’ve performed so far.
