No clean cherry-pick for 202106/202012, need separate PRs. |

…tus via monit (#9367) Backport #9068 to 202012 #### Why I did it Command `monit summary -B` can no longer display the status for each critical process, system-health should not depend on it and need find a way to monitor the status of critical processes. The PR is to address that. monit is still used by system-health to do file system check as well as customize check. #### How I did it 1. Get container names from FEATURE table 2. For each container, collect critical process names from file critical_processes 3. Use “docker exec -it <container_name> bash -c ‘supervisorctl status’” to get processes status inside container, parse the output and check if any critical processes exit #### How to verify it 1. Add unit test case to cover it 2. Adjust sonic-mgmt cases to cover it 3. Manual test
Can you submit separate PRs against 202012/202106 please? |

Hi @yozhao101, I suppose they are already in 202012 and 202106. Please check #9366 and #9367 |
