You for got one example Tobian, Mars Defense Perimeter as shown in Best of Both Worlds. Unmanned, impulse speed, little ships. I think (big maybe) they were stated in The Dominion War SB.
Now as far as Monitors go, I've built one design based off the old FASA Monitor-class. It however has low warp capability, strictly for intercept purposes only. It was developed to replace or supplement the Mars Defense Perimeter Drones for use against superior opponents, i.e. the Borg. I've yet to finish the design, but I have nice images.
Found some more information on the Monitor Type-
A monitor was a special form of warship, little more than a self-propelled floating artillery platform that could move close inshore and give its support to military operations on land.
