Restart Platform-monitor service if one of critical processes running in Platform-monitor container exited or crashed abnormally.
Generally I follow the framework created by Joe to implement this feature in Platform-monitor container.
First, add supervisor-proc-exit-listener event listener option in Supervisord configuration file in Platform-monitor docker container. Supervisord will read a list of critical processes for which to monitor the unexpected crashed and exited.
Second, configure Platform-monitor.service to always auto-restart the service if it stops, with a delay of 30 seconds. Also set a rate limit of 3 restarts within 20 minutes (1200 seconds).
On your switch device, please use docker ps command to list all running docker containers.
Then use docker exec -it container_id bash to login target container. Typing top command
on the shell will display all the processes dynamically and you will spot the process id of one
of the critical processes. Finally type the command kill -9 process_id to terminate one process.
After exiting the container, you can use watch -n 1 docker ps to dynamically see the restart
of Platform-monitor container.
