Introduction
Gatling AMQP support
Usage
handy cli (use AmqpProtocol as console utility) [0.6 feature]
scala> import io.gatling.amqp.Predef._
scala> amqp.declare(queue("q3", durable = true)).run
publish (normal)
implicit val amqpProtocol: AmqpProtocol = amqp
.host("localhost")
.port(5672)
// .vhost("/")
.auth("guest", "guest")
.poolSize(10)
val req = PublishRequest("q1", payload = "{foo:1}")
val scn = scenario("AMQP Publish").repeat(1000) {
exec(amqp("Publish").publish(req))
}
setUp(scn.inject(rampUsers(10) over (1 seconds))).protocols(amqpProtocol)
publish (with persistent)
- PublishRequest.persistent make request DeliveryMode(2)
- known issue: persistent reset request's properties
val req = PublishRequest("q1", payload = "{foo:1}").persistent
publish (with confirmation)
- set "confirmMode()" in protocol that invokes "channel.confirmSelect()"
implicit val amqpProtocol: AmqpProtocol = amqp
.host("localhost")
.port(5672)
.auth("guest", "guest")
.poolSize(10)
.confirmMode()
val req = PublishRequest("q1", payload = "{foo:1}")
val scn = scenario("AMQP Publish(ack)").repeat(1000) {
exec(amqp("Publish").publish(req))
}
setUp(scn.inject(rampUsers(10) over (1 seconds))).protocols(amqpProtocol)
declare queues
implicit val amqpProtocol: AmqpProtocol = amqp
.host("localhost")
.port(5672)
.auth("guest", "guest")
.declare(queue("q1", durable = true, autoDelete = false))
declare exchange and binding
val x = exchange("color", "direct", autoDelete = false)
val q = queue("orange")
implicit val amqpProtocol: AmqpProtocol = amqp
.host("localhost")
.port(5672)
.auth("guest", "guest")
.declare(x)
.declare(q)
.bind(x, q, routingKey = "orange")

consume (auto acked)
implicit val amqpProtocol: AmqpProtocol = amqp
.host("amqp")
.port(5672)
.auth("guest", "guest")
val scn = scenario("AMQP Publish(ack)").exec {
amqp("Consume").consume("q1", autoAck = true)
}
setUp(scn.inject(atOnceUsers(1))).protocols(amqpProtocol)

Run
sbt directly
% sbt
> testOnly io.gatling.amqp.PublishingSimulation
% sbt
> testOnly io.gatling.amqp.ConsumingSimulation
- try
sbt -J-Xmx8192m -J-XX:MaxPermSize=256m for publishing massive messages
shell script to store gatling stdout logs and simulation sources

Library
- amqp-client-3.5.3
- gatling-sbt-2.1.6 (to implement easily)
- gatling-2.2.0-M3 (live with edge)
TODO
- declare exchanges, queues and bindings in action builder context (to test declaration costs)
- make AmqpProtocol immutable
- make Builder mutable
- mandatory
- consume action (manual ack)
