Supervisor: Tagging logs from different processes

The supervisor-stdout plugin will print subprocess log messages to stdout prefixed with the subprocess name.

You can also print subprocess log messages to stdout by setting loglevel = debug in supervisord.conf, but that will also print a lot of other debug information.

@mnaberez Unfortunately, supervisor-stdout is not working with supervisor installed via apt-get on Ubuntu 16.04. It throws the error Error: supervisor_stdout:event_handler cannot be resolved within [eventlistener:stdout].

The alternative (installing via pip) is much more cumbersome. I was able to run it with something like this:

/path/to/supervisord -c /path/to/supervisord.conf

running correctly:

stdout                           RUNNING   pid 1294, uptime 0:03:16
tornado-8000                     RUNNING   pid 1295, uptime 0:03:16
tornado-8001                     RUNNING   pid 1296, uptime 0:03:16

but it doesn't prefix the subprocess name. If I use

[supervisord]
nodaemon = true

in my configuration file, I get the prefix displayed in the output, but not written in the log files.

I'm using a fairly standard setup (a couple of tornado processes and supervisor_stdout) with:

[program:tornado-8000]
command = /path/to/python myfile.py
stdout_events_enabled = true
stderr_events_enabled = true
...

[eventlistener:stdout]
command = /path/to/supervisor_stdout
buffer_size = 100
events = PROCESS_LOG
result_handler = supervisor_stdout:event_handler

Is there an update on this problem or alternative solution?

Wondering the same as @katsar0v . Any alternate solution to this?

Looking for solution to this, too.
