That's correct. The reason for it is entirely historical - the old Big
Brother system only tracked the load average value, so that is what went
on the cpu status display.

It depends on the client software running on your servers. If you're
using the Big Brother client, then by default it doesn't report the
"vmstat" data that is needed to provide a %-value for the cpu
utilisation. The Hobbit client does, and uses this for the "la1" graph.

The answer to your question is that you cannot currently get the %-cpu
graph on the "cpu" status column. You *can* get it into the "trends"
column by adding "TRENDS:*,la:la1" to the host entry in bb-hosts. This
replaces the normal "la" graph with the "la1" graph. But alas, only on
the "trends" page.

It is something that will be improved. I think the 4.3 release is
beginning to look like the big UI improvement release.
