How can I see what’s service logging on console?

I can see the log “Launch Service succeeded”, but I can’t see “service start”

I can’t see the log when I launch application containing service with something like that:

module.exports.onStart = function() 
{
   console.log(“service start”);

}

init.js

tizen.application.launchAppControl(new tizen.ApplicationControl("http://tizen.org/appcontrol/operation/service"),
            "XXX.service1",
            function() {console.log("Launch Service succeeded"); },
            function(e) {console.log("Launch Service failed : " + e.message);});

config.xml:

<tizen:service id="XXX.service1" on-boot="true" auto-restart="true">
        <tizen:content src="service/service.js"/>
        <tizen:name>WebServiceApplication1</tizen:name>
        <tizen:icon src="icon.png"/>
        <tizen:description>Service FotballLive</tizen:description>
    </tizen:service>
