Following can be seen a rule example:

rule "highTranscodingRateRule"
when
    (
    $tot0 := java.lang.Double( $tot0 >=150 ) from accumulate(     
    $m0 := MonitoredComponent( name== "transcodingNode" && metric== "transcondingRate" ) over window:time(1m)from entry-point "MonitoringStream" ,
        average( $m0.getValue() )  ) and
    $tot1 := java.lang.Double( $tot1 >=3 ) from accumulate(     
    $m1 := MonitoredComponent( name== "transcodingNode" && metric== "queueSize" ) over window:time(1m)from entry-point "MonitoringStream" ,
        average( $m1.getValue() )  ) ) 
then
    insertLogical( new Action("pilotTranscodingService","transcodingNode",RuleActionType.COMPONENT_LIFECYCLE_MANAGEMENT,"2","infrastracture-start"));
