Monit vs Supervisord: What are the differences?
Introduction
In this markdown code, we will discuss the key differences between Monit and Supervisord, two popular process monitoring tools used in software development and server management.
Configuration Language: Monit uses a simple, declarative configuration language that allows users to define rules and conditions for process monitoring and management. On the other hand, Supervisord uses an INI file format for its configuration, which allows hierarchical grouping of processes and supports advanced features like process dependencies and event listeners.
Process Control: Monit primarily focuses on process monitoring and automatic recovery. It can start, stop, and restart processes based on defined criteria. Supervisord, on the other hand, focuses on process control, allowing users to manage processes manually, start or stop them individually or in groups without automatic recovery.
Web Interface: Monit provides a built-in web interface that allows users to view the status of monitored processes, manage alerts, and perform manual control operations. In contrast, Supervisord does not have a native web interface. However, third-party tools like Supervisor HTTP can be integrated to provide a web-based management interface.
Alerting Mechanism: Monit supports various alerting mechanisms such as email notifications, custom scripts execution, passive alerts via Unix socket, and integrations with external tools like Slack and PagerDuty. Supervisord primarily relies on logging and does not natively support alerting mechanisms. However, users can configure external log monitoring tools or custom scripts to handle notifications.
Platform Support: Monit is available on a wide range of Unix-like systems, including Linux, FreeBSD, macOS, and Solaris. It can also run on certain Windows platforms. In contrast, Supervisord is primarily designed for Unix-like systems and does not have official Windows support.
Community and Documentation: Monit has an active and thriving community, with extensive documentation and resources available. It is well-maintained and has regular releases. Supervisord also has an active community but its documentation and resources are relatively more limited compared to Monit.
In Summary, Monit and Supervisord differ in their configuration language, process control capabilities, web interface availability, alerting mechanisms, platform support, and community/resources availability.
