No data collected initially = no rrd file created. Find out why.

Turn the polling level in cacti to debug (Settings | Polling level) for one cycle and paste the output of the log file (./cacti/cacti.log). If it contains WEBLOG entries, then don't bother posting since they just clutter up the log. Turn off WEBEVENTS logging and try again.
