supervisorctl merge stdout+stderr to save time

[mrx23dot]

A new parameter would be nice like that prints stdout (possibly longer) first, then stderr (more important) last.

supervisorctl tail xxx both

instead of two steps

supervisorctl tail xxx stdout
supervisorctl tail xxx stderr

Unless there is a way to capture the original intverleaved one

Would save a few seconds everytime we need to investigate.

-tail will be a bit trickier.

A nother small idea, .rstrip() the output when printing to console, since default output is only a few lines long we don't want to waste it on trailing new lines.

But omg supervisord is so much nicer than systemd! Thank you!
