Graph linux cpu usage

[fernandoch]

I am new to Cacti and I am trying to graph cpu usage in a linux box. How can I do it?

I clicked on Create -> New Graphs, then in the dropdown I select ucd/net - CPU Usage but then at the bottom I get the [Unix - Get Mounted Partitions] and I am a bit lost in there.

Any clues? What am I doing wrong?

Thank you
