Is this supposed to be connected to something?

While under the car the other day, I noticed this hole/connector on the bottom of my brake booster (I think that's what it is). Is it supposed to be plugged or connected to some hose or something? What is it's purpose? I can't find this part anywhere in Real OEM.
