Q7680030: I have a check A which depends on check B. Check B is shown as red (failure) but check A is still shown as green (success). Is it a bug?
If check A is indeed successful, it will be shown as green. Only if check A is not successful, it will shown in orange, to indicate that it is not OK as a result of check B.
Dependencies is a feature to avoid a mass notification, all because of a single failure (for instance, a router in the network). All checks that depend on this router will not send out an alert if the router fails, and will be shown as orange. But if the router is OK, and the other checks are ok too, a regular green icon is shown.
