Supervisor

logging

supervisor -> daemon.py -> script.py

• daemon.py implements a while(1) loop
• daemon.py call app logger
• script.py call app logger

1/

• daemon.py and script.py will respect app logger config (rotation, log file naming, log level), whatever [program:daemon] supervisor conf

2/

• if no log conf is defined in [program:daemon] supervisor conf, (meaning stdout_logfile and stderr_logfile is redirected to /dev/null, then nothing else happens.
• if a log conf is defined in [program:daemon] supervisor conf, this will be respected besides app logger conf.

Then:
* app logger can concatenate info from multiple scripts and daemons (supervisor cannot) * specific log file can be produced related to a single daemon (and its subscripts)

Conf for ChaudiereApp:

• app logger concatenate every damons logs
• no log conf in supervisor program conf
