No eyes on glass is a network monitoring term widely used in the operations world. It's origin is believed to have come out of one of the AT&T centers. Essentially, it means techs do not have to monitor crap. They can just be lazy and wait for a ticketing system to do all the work for them. But it really doesn't make any sense, because even though you aren't looking at the monitoring glass, you have to look at the ticketing glass.
