The poller interval is the actual time that the poller will wait between two polling cycles if it was indeed invoked in time by the cronjob.Go to /etc/php5/apache2/and ensure that you have no popen in disable_functions list.Removing popen from disable_functions list should solve your problem.Gandalf from the Cacti forums wrote a nice Guide that you can use and further help can be found on Cacti forums. Make sure you are collecting data at least as often as the step size.If you collect data for 10 min and nothing shows up, then make sure you are actually collecting the data, make sure the values you get are within range, and that they are being used. Print out the values before you update to verify they are what you think they are.
