Newbie - How to graph CPU Usage

[Pulsar]

I've just installed Cacti Version 0.8.7b and configured Lighttpd, MySQL, load, memory, network and ping graphs, but I've got strange problems with CPU Usage graph.

Cpu Usage is rendering, but no graph available. I've got only one CPU (1-core).

Please help.

This tells us, that the taret host does not (yet) implement the SNMP OIDs requested by this template (it requires the HOST MIB)
