Print correlation values on console in gatling

How can we print the values captured using saveAs("myValue") on the console of gatling, like we do System.out.println() in Java?

Solution

  • Values saved with saveAs, are saved into session : Docs : http://gatling.io/docs/2.2.0/session/session_api.html#id2

    Those values are actually logged into console automatically if you turn logging on in settings: resources/logback.xml uncomment :

    <logger name="io.gatling.http.ahc" level="TRACE" /> 
<logger name="io.gatling.http.response" level="TRACE" />

    With this settings you will see this before each reqest:

    Session: Session(<Session desc.>,5846298469383031361-23,Map(<session vars>),1463134760217,8,KO,List(),<function1>)

    Or you have to print your vars in session function: 

    val printSesssionVar = scenario("print session var").exec{
    session =>
      println(session("<your session var>").as[String])
      session
  }
