Re: [Supervisor-users] infinite startup retries?

[Paul Fox]

thanks to you both.  i've clearly been missing out on most of the
documenation for supervisord.

perhaps even _mentioning_ http://supervisor.org in the man page would
help!  honestly -- it's bad enough that the man page doesn't offer
complete documentation, but to not even mention the site where the
documentation does exist is a huge omission.

If you go this route, I did write a program in Perl that does this that you 
could work with:

oh -- startretries is something i can set in the conf file?  i thought
it was an internal parameter of some sort.  where can i find a full
list of the settable values?  i would have expected it to be in the
man page.  the backoff sequence is also not specified -- will the
delay interval eventually stop growing?

thanks,
paul


You might also want to look at the event subsystem available in supervisord.

http://supervisord.org/events.html

You could then have your code respond to, for instance, TICK_60 events 
and decide whether it's the appropriate time to do whatever work they 
are designed to do.

Btw, i think the cron job it's a better solution for this case

[Supervisor-users] infinite startup retries?

[Paul Fox]

is there a way to get supervisor to attempt restarting a process
forever, at some low rate?

i have some services that rely on USB hardware.  when they start, they
detect the hardware and continue, else the exit.  i'd like them retry
once in a while, forever, in case the hardware has been inserted.

as far as i can tell from the man page, once "startretries" (which
undefined in the man page, but appears to be "4") have been attempted,
the process is never tried again.

is my only recourse to run a cron job to do a "supervisorctl start jobname"
every minute or two?
