By what method(s) is devmon detecting that a link is 'down'? I presume you,
er, hacked up some devmon rules to do this? ;) Maybe you can share these
with us? I've not used devmon, so forgive me if they are elementary - it
would still be nice to see them or the config needed to get this working,
and it might encourage more people to use it and your nice looking
devmon-weathermap. Or if this link detection is completely part of devmon by
default, then can you explain how devmon concludes a link is up or down?

Many thanks,
