yeah i've setup monitoring for my mongodb and sql databases and rabbitmq queues too because it happened to me that websites were up, but new data wasn't coming in because of issues at the db or messaging queues levels.

Obviously that's something every software developper could add to his own project, that's not rocket science, but after the nth project, it becomes a bit tiresome :-)

Yes I agree.

I would say health check endpoints are still very useful, and complement what you are offering here. When something is down and there is a panic (but trying to stay calm) having a barrage of checks to play the "Sherlock Holmes" game is useful.

If for example your service says "Mongo is up" but I also see "Mongo Healthcheck is down" it is probably a configuration (connection string) issue or maybe a network issue. Without your check elimination would take longer.
