This article delves into how to leverage Supervisord's process group functionality to flexibly manage specific sets of processes using the supervisorctl command. It details the configuration methods for process groups, including defining groups and programs in the supervisord.conf file, and performing batch restart operations with supervisorctl. Through practical code examples, it demonstrates how to group multiple processes (e.g., process1 to process4) for efficient management, thereby enhancing operational efficiency. Additionally, the article discusses the differences between process group and individual process management, along with best practices in real-world applications, helping readers optimize process monitoring and management strategies based on Supervisord.
