Supervisor is a client/server system that allows its users to control a number of processes on UNIX-like operating systems. Supervisorctl is the command-line client piece of the supervisor which provides a shell-like interface. More information:

  • Show the status of a process (or all processes if process_name is not specified):

supervisorctl status {{process_name}}

  • Start/stop/restart a process:

supervisorctl {{start|stop|restart}} {{process_name}}

  • Start/stop/restart all processes in a group:

supervisorctl {{start|stop|restart}} {{group_name}}:*

  • Show last 100 bytes of process stderr:

supervisorctl tail -100 {{process_name}} stderr

  • Keep displaying stdout of a process:

supervisorctl tail -f {{process_name}} stdout

  • Reload process configuration file to add/remove processes as necessary:

supervisorctl update
