When you launch a test on Flood we extract results using InfoExtractors to write Content-Length and StatusCode headers to the simulation log file.

Please ensure that your test plan extracts the Content-Length header as follows.

response.getHeader("Content-Length")

Example shown below:

import scala.concurrent.duration._

import io.gatling.core.Predef._
import io.gatling.http.Predef._
import io.gatling.jdbc.Predef._


class TestPlan extends Simulation {

  val uuid = List(System.getProperty("uuid"))

  val httpProtocol = http
    .baseURL("http://google.com")
    .acceptHeader("text/html,application/xhtml+xml,application/xml;")
    .acceptEncodingHeader("gzip, deflate")
    .extraInfoExtractor((status, session, request, response) =>
      List(uuid, Option(response.getHeader("Content-Length")).getOrElse("0"), response.getStatusCode.toString))

  val scn = scenario("Scenario Name")
    .exec(http("first_page")
    .get("/"))
    .pause(1000 milliseconds, 5000 milliseconds)

  setUp(scn.inject(ramp(10 users) over (60 seconds))).protocols(httpProtocol)
}
