Seepage from the hose going to the front strut.

I'm new to BMW ownership. I just purchased a 2013 R1200RT with 30K miles on it. Excellent ride!  I was in the garage getting to know the in's and out's and saw a small amount of oil at the bottom of the strut. It appears to be coming from the small hose attached it. I assume it is a vent for the shock. Is this small amount normal or is it time to have it replaced?
