I'm attempting to get Kamon tracing set up with a DataDog reporter for APM. I've noticed the following warning in the DataDog agent logs:
Error getting trace count: "HTTP header \"X-Datadog-Trace-Count\" not found". Functionality may be limited.
I'm wondering if this is a bug and possibly why I'm not seeing every trace get to the dashboard.
Okay... to do what I want to do - instrument a number of classes without having to annotate every method - I'm looking at creating a custom kanela instrumentation module. However, it seems to not be attaching the OnMethodEnter/Exit advice, and my instrumentation module is greyed out on the Kamon status page. (Looking at the kanela debug logging, it loaded my module) Is there something I have to do to activate the module, besides adding my own section to
@ivantopo - Any thoughts on this?
executor-service-capture-on-submittracing system instead of the regular
executor-servicebut it doesn't capture spans on
java.util.concurrent.ScheduledExecutorService(there is no instrumentation for it). Is it a voluntary omission or just something that was never asked for ?
@redkhalil to your quuestions:
- Disabling Kamon via config. There is nothing ready yet but @jtjeferreira put an initial bunch of work here: kamon-io/Kamon#780
- Issue with upgrading from v1 to v2. If you are using Kamon.init, are you 100% sure that the call is happening before any of the Akka HTTP-related classes are loaded?
- Preferred version: latest! I know that Kamon is not working well with Akka HTTP 10.0 and early 10.1 so the latest 10.1 should be fine
I've figured out what was missing, I still need the javaagent, which I initially removed. Now I got it working. The information is out there on the website, just that it's a bit of a puzzle that you need to put together ;)
fork in run : = truein
build.sbt, it throws

Please remove -javaagent from your startup arguments and contact Kanela support.: java.lang.NoSuchMethodError: 'void kamon.instrumentation.akka.instrumentations.VersionFiltering.onAkka$(kamon.instrumentation.akka.instrumentations.VersionFiltering, java.lang.String, scala.Function0)'any idea why?
