[Xymon] CPU USAGE DISPLAY (CPU Statistics)

[Jeremy Laidman]

>From the "top" man page:

"There is a possible workaround if you define the CPULOOP=1 environment
variable. The top command will be run one extra hidden loop for CPU data
before standard output."

You could define this in the appropriate cfg file on each client.
