What are the functions of Supervisor in Linux?

In Linux, Supervisor primarily functions as follows:

1. Process management: Ability to start, stop, restart, and monitor various processes, including applications, daemons, and scheduled tasks.
2. Process control: You can adjust the process’s start order, start interval, restart policy, etc., to ensure that the process runs as expected.
3. Process monitoring: Ability to track real-time status of processes, including metrics such as CPU usage, memory usage, and runtime.
4. Log management: it allows for the collection and organization of process logs, making it easier to view and analyze.
5. Error handling: can handle abnormal exits and crashes of processes, and can set strategies such as automatic restarts.
6. Multi-process management: can simultaneously manage multiple processes, assigning each process its own resources and configurations.
7. Web management interface: Supervisor offers a web interface that allows process management and monitoring through a browser.

Overall, supervisors can help system administrators more easily manage and monitor various processes running on Linux systems, leading to improved stability and reliability of the system.
