加特林3.0.3在注射前暂停25秒。
我正在使用Radius插件bpabdelkader/gatling-radius进行负载测试，以测试Radius服务器。
我的示例方案如下：
import io.gatling.core.Predef._
import com.ngenia.radius.Predef._
import com.ngenia.radius.protocol._
class RadiusSimulation extends Simulation {
implicit val radiusProtocol: RadiusProtocol = radius
.host("10.20.30.40")
.sharedKey("mySharedKey")
.replyTimeout(100) // 100 ms
val scn = scenario("Access Request")
.feed(csv("data/dataFeeder.csv").circular)
.exec(
radius("Access Request")
.username("${username}")
.password("${password}")
.properties(
Map(
"NAS-Identifier" -> "${NAS-Identifier}",
"NAS-IP-Address" -> "${NAS-IP-Address}",
"Calling-Station-Id" -> "${Calling-Station-Id}",
"Called-Station-Id" -> "${Called-Station-Id}"
))
.authenticate()
)
setUp(scn.inject(atOnceUsers(1000))).protocols(radiusProtocol)
}
启动后，我可以看到1000名用户在注入开始之前等待了25秒

另一点：如您所见，为完成最终请求而进行的1秒测试+/-几秒钟进行了15秒！!!!

就上述问题分享经验时，我的Radius呼叫似乎正在阻塞，这就是演员连续执行顺序的原因！！！！
该解决方案包括使用Scala Future / onComplete块使Radius调用异步。
这是主要的自定义操作：
package com.ngenia.radius.action
import scala.util.{Failure, Success}
import io.gatling.core.action._
import io.gatling.core.session.Session
import io.gatling.core.stats.StatsEngine
import io.gatling.commons.util.Clock
import scala.concurrent.Future
import scala.concurrent.ExecutionContext.Implicits.global
import com.ngenia.radius.client
import com.ngenia.radius.client.RadiusUtils
import com.ngenia.radius.protocol.RadiusProtocol
import com.ngenia.radius.request._
case class RadiusAction(
requestType: Type,
radiusAttributes: RadiusAttributes,
radiusProtocol: RadiusProtocol,
clock: Clock,
statsEngine: StatsEngine,
next: Action
) extends RadiusLogging {
override def name: String = "RADIUS"
override def execute(session: Session): Unit = {
implicit val iSession = session
val start = clock.nowMillis
val future = Future {
client.RadiusClient.sendRequest(radiusProtocol, requestType, radiusAttributes)
}
future.onComplete {
case Success(response) => {
log(start, clock.nowMillis, response._2, radiusAttributes.requestName, session, statsEngine)
next !
session
.set("Acct-Session-Id", RadiusUtils.sessionId)
.set("Framed-IP-Address", RadiusUtils.framedIPAddress(response._1))
}
case Failure(e) => e.printStackTrace
}
}
}
