Uplink: [WARN] state

[FlorianHeigl]

Hi,

i looked at the code but still haven't figured out what the criteria are that make the check go to a WARNING state. It's happening on a few devices but I couldn't make out a pattern.
It's got a warning on 4 out of 120 devices, and they seem all to be reachable.

could you tell me about the intention of that check? i'll gladly write a proper check man page once I understand it.
