no eyes on glass 

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.

In our monitoring center we have no eyes on glass.

eyes on glass 

It is when a particular software application or a hardware system requires continuous monitoring. Technicians take breaks and closely monitor traffic, tickets from field and possibly complicated consoles full of graphs and charts. Mostly done on a mission critical application or when a major event is happening on a otherwise unimportant application.

Also look at no eyes on glass for stopping monitoring of a critical application.
