A complaint I hear a lot is that the critical icon looks to much like the down icon when just scanning. Is there a way to change the Red circle with ! to something else like an orange circle?
I found an answer for this which might not be everyones way. I changed the Node status back to Classic View. You can do this here: Settings > All Settings > THRESHOLDS & POLLING > Polling Settings > NODE STATUS CALCULATION > Node Status > Change it to Classic.This creates an orange/yellow triangle for nodes in warnings. This also fixed a bunch of issues where our nodes would show down when a volume or interface was down - now its back to the little square that indicates something is wrong with an interface or volume not the node it self.
