supervisorctl - supervisorctl Documentation

Supervisor is a client/server system that allows its users to monitor and control a number of processes on UNIX-like operating systems.

It shares some of the same goals of programs like launchd, daemontools, and runit. Unlike some of these programs, it is not meant to be run as a substitute for init as "process id 1". Instead it is meant to be used to control processes related to a project or a customer, and is meant to start like any other program at boot time.

supervisorctl

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, stop and start subprocesses of, and get lists of running processes of a supervisord.

The command-line client talks to the server across a UNIX domain socket or an internet (TCP) socket. The server can assert that the user of a client should present authentication credentials before it allows him to perform commands. The client process typically uses the same configuration file as the server but any configuration file with a [supervisorctl] section in it will work.



This section makes reference to a BINDIR when explaining how to run the supervisord and supervisorctl commands. This is the "bindir" directory that your Python installation has been configured with. For example, for an installation of Python installed via ./configure --prefix=/usr/local/py; make; make install, BINDIR would be /usr/local/py/bin. Python interpreters on different platforms use a different BINDIR. Look at the output of setup.py install if you can't figure out where yours is.

supervisorctl Command-Line Options

Configuration file path (default /etc/supervisord.conf)
Print usage message and exit
Start an interactive shell after executing commands
URL on which supervisord server is listening (default "http://localhost:9001").
Username to use for authentication with server
Password to use for authentication with server
Keep a readline history (if readline is available)

action [arguments]

Actions are commands like "tail" or "stop". If -i is specified or no action is specified on the command line, a "shell" interpreting actions typed interactively is started. Use the action "help" to find out about available actions.

To start supervisorctl, run $BINDIR/supervisorctl. A shell will be presented that will allow you to control the processes that are currently managed by supervisord. Type "help" at the prompt to get information about the supported commands.

The supervisorctl executable may be invoked with "one time" commands when invoked with arguments from a command line. An example: supervisorctl stop all. If arguments are present on the command-line, it will prevent the interactive shell from being invoked. Instead, the command will be executed and supervisorctl will exit.

If supervisorctl is invoked in interactive mode against a supervisord that requires authentication, you will be asked for authentication credentials.
