I have a data center that has two air units. I currently ping each for availabilty and also read in some snmp values.
These air units work in such a way that only one of them is running at a time. They are setup in failover mode so if unit one should fail, the other will come online.
I am currently monitoring both devices however, because only one is on at a time, the second unit shows as failed.
I would like to be able to setup something similar to:
Unit A is primary. If Unit A fails, send me an alert that tells me Unit A failed but also send me a notice that Unit B has come online.
Any thoughts how I might be able to do this and also not have the 'currently in standby mode' unit not show red in my device/monitors list?
thanks
