A system for allowing the control of process state on UNIX.
The supervisor is a client/server system that allows its users to control a number of processes on UNIX-like operating systems.
The server piece of the supervisor is named “supervisord”. It is responsible for responding to commands from the client process as well as restarting crashed processes.
The command-line client piece of the supervisor is named “supervisorctl”. It provides a shell-like interface to the features provided by supervisord. From supervisorctl, a user can connect to different supervisord processes, get status on the subprocesses controlled by a supervisord, stop and start subprocesses of a supervisord, and get lists of running processes of a supervisord.
