Kamon not started using sbt-aspectj-runner

[reee...@gmail.com]

Hi guys,

I wanted to try out Kamon but have small issue.

In my main class I've added the starting of Kamon

object Main extends App with AppConfig with BaseService {

Kamon.start()
....

And in my build.sbt I've added your plugin

addSbtPlugin("io.kamon" % "aspectj-runner" % "0.1.2")

but it's saying kamon is not started and the api is not working. If I start it by just running manually the main class api is working just fine.

Any ideas?

Hi reeebuuk,

that sound like an Actors System was started before kamon.start() can you check this?

I also recommend that you update the sbt-aspectj-runner to the 0.1.3 version.

BTW: here an running example.

Cheers,

Diego

Thx Diego for the example. Will take a look today and see if I can get it to work.

Starting of Kamon was before the starding of akka system. Like in the example.

Hi Diego, tried the new version of plugin but nothing...

Here is the link to the project
https://bitbucket.org/kuzelac/apt-billing/overview

any ideas?

[Diego Parra]

Hi,

i have a good and a bad news, let's start with the good:

In build.sbt you need include kamon-log-reporter dependency

"io.kamon" %% "kamon-core" % kamonVersion,

"io.kamon" %% "kamon-scala" % kamonVersion,

"io.kamon" %% "kamon-akka" % kamonVersion,

"io.kamon" %% "kamon-system-metrics" % kamonVersion,

"io.kamon" %% "kamon-annotation" % kamonVersion,

"io.kamon" %% "kamon-log-reporter" % kamonVersion,

"io.kamon" %% "kamon-statsd" % kamonVersion

then in application.conf

we need include the modules that you can run (all disabled):

 modules {

    kamon-log-reporter.auto-start = no

    kamon-statsd.auto-start = no    

    kamon-system-metrics.auto-start = no

    kamon-annotation.auto-start = no

  }

and finnally in Main.scala 

package hr.com.blanka.apartments

import akka.actor.ActorSystem

import akka.event.{Logging, LoggingAdapter}

import akka.http.scaladsl.Http

import akka.stream.ActorMaterializer

import hr.com.blanka.apartments.http.BaseService

import hr.com.blanka.apartments.price.PriceRangeActor

import hr.com.blanka.apartments.utils.{AppConfig, PricingConfig}

import kamon.Kamon

object Main extends App with AppConfig with BaseService with KamonSupport//with MongoDbConfiguration {

{

  implicit val system = ActorSystem("booking")

  val processor = system.actorOf(PriceRangeActor(PricingConfig(pricingConfig)), "processorActor")

  val view = system.actorOf(PriceRangeActor(PricingConfig(pricingConfig)), "viewActor")

  override protected implicit val executor = system.dispatcher

  override protected val log: LoggingAdapter = Logging(system, getClass)

  override protected implicit val materializer: ActorMaterializer = ActorMaterializer()

  Http().bindAndHandle(routes(processor, view), httpInterface, httpPort)

}

trait KamonSupport {

  Kamon.start()

  sys.addShutdownHook(Kamon.shutdown())

}

and if you run the application with aspectj-runner:run all is working fine....... 

The bad.... if you uncomment [with MongoDbConfiguration] the weird error appears... i need research some time more in order to find the cause.

Cheers,

Diego.

Hi Diego,

thanks for taking the time to resolve my issues.

I got the same exceptions when I've been try to get it to work. Was hoping that was me doing something wrong :/
