cpu
       Returns the average TMM cpu load for the given interval.

SYNOPSIS
       cpu usage (
		       '1sec' | '5secs' | '15secs' |
		       '1min' | '5mins' | '15mins' |
		       'all_seconds' | 'all_minutes'
		   )?

DESCRIPTION
       The cpu usage command returns the average TMM cpu load for the given
       interval. All averages are exponential weighted moving averages over
       the interval.

       Syntax

       cpu usage [1sec | 5secs | 15secs | 1min | 5mins | 15mins | all_seconds
       | all_minutes]

	    * Returns the average TMM cpu load for the given interval

RETURN VALUE
VALID DURING
       ANY_EVENT, GLOBAL_GTM

EXAMPLES
	when HTTP_REQUEST {
	  if{ [cpu usage 5sec] <= 1} {
	    pool1
	  } else {
	    HTTP::redirect "http://anotherpool.com"
	  }
	}


	when RULE_INIT {
		foreach slice [split "1sec|5secs|15secs|1min|5mins|15mins|all_seconds|all_minutes" "|"] {
			log local0. "\[cpu usage $slice\]: [cpu usage $slice]"
		}
	}

	# Log output (from an unloaded LTM unit):

	[cpu usage 1sec]: 0
	[cpu usage 5secs]: 0
	[cpu usage 15secs]: 0
	[cpu usage 1min]: 0
	[cpu usage 5mins]: 0
	[cpu usage 15mins]: 0
	[cpu usage all_seconds]: 0 0 0
	[cpu usage all_minutes]: 0 0 0
