You're right, it's an indicator of possible problems, but there are
plenty of use cases where 0% idle (even over some extended time
period) isn't something alarming. I use it often together with

	*.cpu	delay=30

in bb_event_generator.cfg, since on most systems high load and/or
high CPU usage indicate a problem if they persist for a long time.

This is nearly fine. Only that uxmon is falling back to idle_red=10 if
idle_red is not set ... and 0 is considered "not set" (argh).

Probably, idle_red=-1 will do the trick.

The cpuload test checks the load average. So if you feel unhappy with
"load", either drop it completely (you are not forced to use it :-)) or
if you still want to get graphs try setting the limits to -1 as 
suggested above.

The cpuload test is independent of the load test (it's the one reporting
"CPU load = 2.21" in your example output). BTW: it's arguments are
cpu_yellow and cpu_red for specifying the load average at which yellow/
red should be reported.

Best regards,
Tom
