For both the OpenBSD firewalls and the Linux servers, the Processors graph on the Overview page seems to be based on "Device (ucd_ss_cpu)". But the Processors graph which does work looks to be based on "Device (processor)".

So it seems that "Device (ucd_ss_cpu)" is not populated for OpenBSD, where Observium thinks it should be.

Here is the RRD Command for a Linux device which works;

Thank you very much for your time, and a great system. The more I use Observium, the more I love it.

Cheers, Andy.
