Got cacti 0.86h setup and tried to setup a sample, after all done (data input method, data source, new graph and tree (with item) done, go to 'graph' site, but I saw no curve of data flow. I tried the 'rrdtool' maually and it did only generate a blank picture without data flow. Help wanted and thank you in advance.
You surely remembered to set up crontab for running poller.php every 5 mins? Then please goto Settings -> Logging Level and set tgis to DEBUG for ONE polling cycle. Have a look at log/cacti.log then.
