I'd say graph them per hour.  A measurement of "per 30 minutes" 
doesn't roll very well off the tongue.  Even a "per 15 minutes" seems 
better than 30 minute increments.  If they are reset each time 
you read them, they would seem to be an absolute value.

Yes, I do roughly the same thing and graphing these with RRDTool 
gives a great view into the activity of a web server or a proxy
That's what I use it for, and the group responsible for these 
types of servers often tunes their servers based on the feedback 
the graphs are giving to them.
