So I followed the following tutorial ~~[http://it.toolbox.com/wiki/index.php/InstallMuninonCentos" target="blank">](http://it.toolbox.com/wiki/index.php/In … _on_Centos">http://it.toolbox.com/wiki/index.php/InstallMuninon_Centos](, and have installed munin. I can see all of my graphs…. the only problem is that they are all blank! Am I completely missing something here? Do I need to do something to get the data into them?
There is a cron job running what I believe to be every 5 minutes.
