Unraid Container Healthcheck. Checks docker service for the status of all containers besides Blacklist array, attempts to start any down containers, and reports to Unraid if any fail. Also checks in to healthchecks.io unless any down containers don't start, so healthchecks.io will alert if a checkin hasn't occurred.
