You have to do the work then. I have a script that calculates queries per second by getting the count of queries from this sampling interval subtracting it from a previous interval then dividing it by number of seconds passed and voila you have queries/sec. You then use gmetric to send that to Ganglia. This is an implementation for disk stat metrics.
