The Unicorn configuration snippet provided by Chris Wanstrath offers a method for managing a Unicorn server using the God monitoring tool, focusing on the master process rather than individual worker processes. The script sets parameters for starting, stopping, and restarting the Unicorn master, using specific system signals to manage these actions and a custom thread to monitor and control the memory usage of worker processes. If any worker exceeds the defined memory limit, it is gracefully terminated, allowing the master process to automatically spawn a new worker, thereby maintaining optimal resource usage. The configuration also includes conditions for process lifecycle management, such as handling process flapping and memory or CPU usage thresholds, while emphasizing that memory usage checks primarily apply to the master process. For workers, a separate monitoring thread ensures that excessive memory consumption is addressed by terminating non-compliant processes to sustain server performance.
