Summary
Supervisor is a free client/server system for monitoring and controlling processes on UNIX-like operating systems. It can start processes, report their status, and restart them after crashes. Administrators configure per-process behavior in an INI-style file, including failed-process restarts and automatic log rotation. Processes can have priorities and be grouped for coordinated start or stop operations. Supervisor provides a command-line client, an optional browser interface, and an XML-RPC interface; the browser view can control and display process status when its HTTP server is enabled. Authentication can be required for commands over UNIX-domain or TCP sockets. Its event-notification protocol can be used by programs written in any language, and it offers extension points for Python developers. Supervisor can be installed with pip or from a downloaded distribution, including on systems without internet access. It is intended for project- or customer-related processes, not as a replacement for init as process ID 1. It runs on supported UNIX-like systems and does not run under Windows.
Who it is for
Supervisor suits system administrators managing project- or customer-related processes on UNIX-like systems. It is not intended to replace init as process ID 1.
What is good
- Restarts processes after crashes
- Groups processes for coordinated start and stop operations
- Offers command-line, browser, and XML-RPC interfaces
- Can be installed from a downloaded distribution
What to know first
- Does not run under Windows
- Configuration files may contain unencrypted credentials
- Arbitrary configured paths can create symlink-attack vulnerabilities
Verdict
Supervisor offers process monitoring, restart controls, and several management interfaces for UNIX-like systems. Protect its configuration files and account for the documented path-related security risk.
