Yes this is possible with Guvnor 5.2 onwards.

The user-guide explains how to use the Guided Rule Editor (but not specifically CEP features).

Read that and give it a try - it's reasonably intuitive (not an excuse for poor documentation though) and come back here with questions.

With kind regards,

Mike

Hi all,
i am novice on GUVNOR, but i would like to define my fusion rules by graphical tool.

An example of my rules is:

rule "radiation-event"
    salience 10
    no-loop
    when
        $obs    : RadiationObservation( $obsLocation : location, value > 10 ) over window:length(1) from entry-point lowLevelSensorStream
        not RadiationEvent( this meets[ 25s ] $obs, location geoIsWithinDistance[ 5m ] $obsLocation )
    then
        insert(new RadiationEvent( $obs, "Radiation over 10", Event.THREAT_HIGH, $obsLocation, $obs.getSensor() ));
end

rule "radiation-update"
    salience 5
    no-loop
    when
        $obs    : RadiationObservation( $obsLocation : location, value > 10 ) over window:length(1) from entry-point lowLevelSensorStream
        $event     : RadiationEvent( this meets[ 25s ] $obs, location geoIsWithinDistance[ 5m ] $obsLocation )
    then
        Event e = Event.clone($event);
        e.addObservation($obs);
        insert( e );
        retract($event);
        retract($obs);
end

Is it possibile to define rules such the above using GUVNOR?
Are there some documentation or tutorial?

Thanks a lot in advance,
Matteo Cusmai.
