Seems like a bizarre thing to monitor. Are you doing this one some brain-dead platform that lets you change ifNames, like Extreme?

I don't think it's something which is particularly overhead-intensive, but it still strikes me as an odd thing to want to monitor.

Hello Tom,

I've added
$port['alert_array']['ifName'] = $port['ifName'];
in  ports.inc.php  just to see if it all works as I wanted and -- yes,
it does exactly what I need.

I  of  course  agree this is not the right way of doing it, because it
adds  needless  work every poll (which I'm doing every minute, instead
of  usual  five)  --  which brings me to next question, and I would be
perfectly happy with checking it every hour.

Maybe   Alerting   facility  could  be  extended  with  some  low-load
low-severity  alert  class, which gets checked every n poll cycles? Or
some option similar to Alert Delay, like Check Interval.

Thank you for your reply :)

PS.  Observium  is  great.  I'm  using it for 3 days and already can't
figure out how I managed without it so far :)
