However, on the CPU column the graph being used is for load average. It graphs correctly so for the example above the graph would plot at 0.87 load (max being 1.0).
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.
My question is how to specify that I want certain hosts be have their CPU graphed as a percentage rather than load average? Does hobbit have a % graph already in hobbitgraph.cfg (maybe la1)??
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.
