I've been thinking about adding rrd style output to collectl but am 
waiting for someone to raise their hand and say they'd like to work with 
me.  As for perl being too heavyweight, collectl uses less than 0.1% of 
the cpu reporting about 100 different variables.  If you want less 
frequent samples as most rrd users do, you can probably get it down to 0.01%
