Superlance plugins enable enhanced monitoring and control of supervisord instances. These plugins provide alerts and automated actions for process failures, system load limitations, and process health issues.
One of the key features of Supervisor is its simplicity. The program is configured through an easily understood INI-style config file. This file provides various per-process options that enable you to restart failed processes and automate log rotation, making your life substantially easier. Another great feature of Supervisor is that it is centralized, which means that it offers users one place to start, stop, and monitor their processes. Processes can be controlled individually or in groups. Additionally, you can configure Supervisor to give you a local or remote command line and web interface for ease of use.
Efficiency is another aspect of Supervisor that stands out. Subprocesses are started through fork/exec and don’t daemonize. This allows the operating system to signal Supervisor the moment a process terminates. This differs from other solutions that rely on PID files and periodic polling to restart failed processes, which can be problematic. The Supervisor software is extensible, allowing programs written in any language to use its straightforward event notification protocol. It also comes with an XML-RPC interface for control and was built with extension points that Python developers can leverage.
Supervisor is extremely compatible, as it works on virtually everything except for Windows. It has been tested and is supported on popular systems like Linux, Mac OS X, Solaris, and FreeBSD. One significant advantage of Supervisor is that it is written entirely in Python, which means that installation does not require a C compiler. This makes it easy for people to get started and put the program to use. Finally, while Supervisor is still under active development, it is not a new piece of software. It has been around for years and is currently used by many servers across the world. In conclusion, I highly recommend Supervisor and the superlance package for those looking for an efficient and effective process control solution.
