Hello,
Since upgrading from Gatling 3.0.5 to 3.5.1, we’re getting the following sporadic error.
12:58:18.594 [ERROR] i.g.c.c.Controller - Actor io.gatling.core.controller.Controller@4d4df077 crashed on message Some(Start(io.gatling.core.scenario.Scenarios@37fff86b)) java.util.concurrent.TimeoutException: Future timed out after [5 seconds] at scala.concurrent.impl.Promise$DefaultPromise.tryAwait0(Promise.scala:212) at scala.concurrent.impl.Promise$DefaultPromise.ready(Promise.scala:219) at scala.concurrent.impl.Promise$DefaultPromise.ready(Promise.scala:104) at scala.concurrent.Await$.$anonfun$ready$1(package.scala:174) at akka.dispatch.MonitorableThreadFactory$AkkaForkJoinWorkerThread$$anon$3.block(ThreadPoolBuilder.scala:174) at java.util.concurrent.ForkJoinPool.managedBlock(ForkJoinPool.java:3313) at akka.dispatch.MonitorableThreadFactory$AkkaForkJoinWorkerThread.blockOn(ThreadPoolBuilder.scala:172) at scala.concurrent.Await$.ready(package.scala:124) at io.gatling.core.stats.DataWritersStatsEngine.start(DataWritersStatsEngine.scala:89) at io.gatling.core.controller.Controller$$anonfun$1.applyOrElse(Controller.scala:63) at io.gatling.core.controller.Controller$$anonfun$1.applyOrElse(Controller.scala:54) at scala.runtime.AbstractPartialFunction.apply(AbstractPartialFunction.scala:35) at akka.actor.FSM.processEvent(FSM.scala:804) at akka.actor.FSM.processEvent$(FSM.scala:801) at io.gatling.core.controller.Controller.processEvent(Controller.scala:44) at akka.actor.FSM.akka$actor$FSM$$processMsg(FSM.scala:798) at akka.actor.FSM$$anonfun$receive$1.applyOrElse(FSM.scala:793) at akka.actor.Actor.aroundReceive(Actor.scala:537) at akka.actor.Actor.aroundReceive$(Actor.scala:535) at io.gatling.core.akka.BaseActor.aroundReceive(BaseActor.scala:25) at akka.actor.ActorCell.receiveMessage(ActorCell.scala:577) at akka.actor.ActorCell.invoke(ActorCell.scala:547) at akka.dispatch.Mailbox.processMailbox(Mailbox.scala:270) at akka.dispatch.Mailbox.run(Mailbox.scala:231) at akka.dispatch.Mailbox.exec(Mailbox.scala:243) at java.util.concurrent.ForkJoinTask.doExec(ForkJoinTask.java:289) at java.util.concurrent.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1056) at java.util.concurrent.ForkJoinPool.runWorker(ForkJoinPool.java:1692) at java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:157)
It seems like Graphite initialization times out after 5s from time to time. 3 questions:
1. Does the configuration below look right?
graphite {
#light = false # only send the all* stats
host = “myhost.com” # The host where the Carbon server is located
port = 2004 # The port to which the Carbon server listens to (2003 is default for plaintext, 2004 is default for pickle)
#protocol = “tcp” # The protocol used to send data to Carbon (currently supported : “tcp”, “udp”)
#rootPathPrefix = “gatling” # The common prefix of all metrics sent to Graphite
#bufferSize = 8192 # Internal data buffer size, in bytes
#writePeriod = 1 # Write period, in seconds
}
2. Is there a way to configure this timeout value?
3. Is there any guidance you can provide to get past this issue?
Thank you!
