title: Gatling - How to set gatling console log level in scala
body: <p>I have created a maven project that will generate a jar file with all my simulations in it and when I run it, the console log level is too high. There is too much unusefull informations for me. 
  Is there a way to configure it in the code ? Here is my code: </p>
  
  <pre><code>import io.gatling.app.Gatling
  import io.gatling.core.config.GatlingPropertiesBuilder 
  import io.gatling.core.config.GatlingConfiguration
  
  object Engine extends App {
      val props = new GatlingPropertiesBuilder
      if(System.getProperty("resultsFolder") == null){
        props.resultsDirectory("results")
      }else{
        props.resultsDirectory(System.getProperty("resultsFolder"))
      }
  
      props.dataDirectory("data")
        props.simulationClass(System.getProperty("simulationClass"))
  
      Gatling.fromMap(props.build)
    sys.exit()
  }
  </code></pre>
  
  <p>And here is the tree of my directory:</p>
  
  <pre><code>¦   dependency-reduced-pom.xml
  ¦   pom.xml
  ¦

      +---main
