ID: 10895 Title: docker_container_status: discovery fix where healthcheck is not available Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 A Healthcheck can be explicitly blocked for a container. In consequence, there will be no information concerning the health status. For such instances, the service should not be discovered. This change implements this behaviour.
