I got a great response, with some large hosting providers sending me literally gigabytes of data. The diversity of data I’ve gotten will really help make this tool much better. When Daniel is back from vacation we will start developing the algorithm.

You could use mysqladmin’s ‘–count’ switch and wait till it ends or, if you’re hit by this bug[1] (like me) you may want to force printing awk’s output with fflush() or system()[2]:

mysqladmin ext -i1 | awk ‘/Queries/{q=$4-qp;qp=$4} /Threads_connected/{tc=$4} /Threads_running/{print q, tc, $4; fflush()}’ | tee output

I’d use screen, myself. It is one of the most important tools ever invented for Unix. I can’t live without it.
