1. I don’t, in general all of them are restarted automatically. I have monitoring configured for services, not containers themselves.
2. Yes, looking at the original Dockerfile/Containerfile if they have HEALTHCHECK keyword you can assume that they do something.
3. Person building the container, often it doesn’t make sense to create a healthcheck at all. Some times healthcheck feature is provided by application as well, it still needs to be part of the containerfile.
4. Better to monitor your service (application+db+proxy+queue+whatever), not containers in isolation.
