Jobs can have four different statuses. Additionally, the instance can have the “Lost connection” state, blue, that takes precedence over job statuses.
Green for OK, Yellow for Warning, and Red for Alarm. Tasks can be without status, and the no-status icon is black.
Statuses will propagate, so the worst alarm state, Alarm is worse than Warning, Warning is worse than alarm, will propagate from the job status to the job group. The job group propagates to the instance. The instance status propagates to the instance group. The instance group propagates to the instance hub or domain.
