Percona Disk Space displaying NaN

Hi

I’ve downloaded the Linux template and have managed to get statistics working for all graphs except for disk usage.

I have tried setting the volume as “/dev/vda3” and “vda3” but to no avail. I checked the cacti log and no errors found.

Is there anything else I can look at?

For disk usage, it should be a first column from “df” output, see http://www.percona.com/doc/percona-m…templates.html
