Trace File Metrics

Hi all,

I read from Appian Documentation that a Trace File Metrics (web_apis_trace.csv) log (available since Appian v16.3) could be found for tracking Web API Performance, but I cant find it on my server.

https://forum.appian.com/suite/help/16.3/Logging.html#Web_API_Performance_Logs

I do have a Web API set up with all other Summary File and Details File Metrics logs present; Only the Trace File Metrics log is missing.

Do you know if this log should be always presented? or only at a certain circumstance this log would be generated?
