[Supervisor-users] Question about child python processes

[Vincent Derelle]

Hello,

We wrote an internal tool inside our organisation in python. We're trying to get it to play nicely with supervisord. We came across the known python buffered output issue where the python child process does not
Write to the stdout log file. Instead we need to pass a -u parameter to the python interpreter in order to properly get the print statements written to the stdout log file. Our program also uses to Python logging
Librairy extensively. Unfortunately, even with specifying a -u parameter we are unable to get the logging.info("information displayed") lines written to the stdout logfile.

Is anyone aware of this bug? Is there any fix for it?

Thank you,
Vincent

Check the log level?

The unbuffered output (-u) parameter will have no bearing on the function
of your python logging lib calls.

I suggest you tinker with the setup for the logger until you get it working
- does it work outside supervisor? Running within supervisor or standalone
will likewise have no bearing on the logging library.
