27 # Common code for all CPU load checks. Please do not mix this up
28 # with CPU utilization. The load is at any time the current number
29 # of processes in the running state (on some systems, like Linux,
30 # also Disk wait is account for the load).
33 # load is a triple of three floats: average load of
34 # the last 1, 5 or 15 minutes
