OItsMAK opened a new issue #7778: How can we do health checks on Druid processes? URL: https://github.com/apache/incubator-druid/issues/7778 We use Druid and would like a way to know when its processes have started up successfully. Something like the `ruok` check on zookeeper (explained [here](https://zookeeper.apache.org/doc/r3.1.2/zookeeperAdmin.html), example [here](https://stackoverflow.com/a/55609944)). The point of this is problematic starts and/or rolling updates of the Druid Docker containers, where HealthChecks come in handy. Currently, the methods that come to my mind are simple `min_healthy_time` waits, Or checking the announcements of Druid nodes in `Zookeeper`, which is a weird method since it includes setting up some sort of monitoring on registered `ZK` nodes, or contacting `ZK` directly.
