Also, if you only want the _Total_ processor usage and have NSCP 
installed you can access the perfmon counter with a check_command like:

define command{
       command_name check-processor-nscp
       command_line $USER1$/check_nt -H $HOSTADDRESS$ -v COUNTER -l 
"\\Processor(_Total)\\% Processor Time","Processor Used %2.f%%" -p 12489
       }

(NB I run nscp on port 12489 hence the -p argument).

Steve.
