I envy you your hardware that you can afford to poll at least once every half second. :-) The place you've put "0.5" is the "heartbeat". This is how often (in seconds) you must update the RRD to avoid having unknown data points added. I usually set it to 2*step so I can miss one update and rrdtool will fudge it. This is a hold-over from when my polling mechanism was too slow. The heartbeat has to be at least as large as the step. Where you set it depends on what you want rrdtool to do when you're not on time. >As far as I can tell from the docs, everything is right.
