How to get file name and line number in GAE Python logging logging.info logs?

Question

A timestamp is available in the logs, but the "source file name" and "line number" not logged with each log message.

How to write file name and line number in GAE Python logging.info (or logging.warn or logging.error and others)?

By "source file name" I mean the Python code file (* .py) that generated the log.

Answer 1

In main.py add:

 formatter = logging.Formatter('%(levelname)-8s %(asctime)s %(filename)s:%(lineno)s] %(message)s') logging.getLogger().handlers[0].setFormatter(formatter) 

Answer 2

Have you tried watching logging formatters ?

It should look something like this:

 formatter = logging.Formatter( '[%(asctime)s] p%(process)s {%(pathname)s:%(lineno)d}' ' %(levelname)s - %(message)s','%m-%d %H:%M:%S')
