Q My program never starts and supervisor doesn't indicate any error?
A
Make sure the x
bit is set on the executable file you're using in
the command=
line of your program section.
Q
I am a software author and I want my program to behave differently
when it's running under :program:supervisord
. How can I tell if
my program is running under :program:supervisord
?
A
Supervisor and its subprocesses share an environment variable
:envvar:SUPERVISOR_ENABLED
. When your program is run under
:program:supervisord
, it can check for the presence of this
environment variable to determine whether it is running as a
:program:supervisord
subprocess.
Q
My command works fine when I invoke it by hand from a shell prompt,
but when I use the same command line in a supervisor program
command=
section, the program fails mysteriously. Why?
A
This may be due to your process' dependence on environment variable
settings. See :ref:subprocess_environment
.
Q How can I make Supervisor restart a process that's using "too much" memory automatically?
A
The :term:superlance
package contains a console script that can be
used as a Supervisor event listener named memmon
which helps
with this task. It works on Linux and Mac OS X.
