Please have a look
@/all people, I just disabled threaded conversations in this channel.. It was enabled for a couple weeks because it seemed like it could help bringing some order to different conversations happening at the same time but to be honest, it makes it harder to figure out if there are any replies on any of the topics so I turned back off. If you have a pending question in a thread that I didn't get to, please post it again here. Thanks!

Now why is it that Kamon.timer returns a metric.Metric.Timer which is not a metric.Timer hence it has no start() method? Is it mandatory to add tags to get a metric.Timer?
it is not mandatory to add tags, but it is mandatory to decide whether you want tags or not. If you don't want any tags you can use Kamon.timer(....).withoutTags() to get an instrument that doesn't have any tags
@ivantopo Please help me with this question

@Arpit1596 regarding Lagom.. long story short would be that at the moment, we do not support Lagom at the moment, although we are trying to. I was trying to make it work in development mode but it all breaks down for a few reasons:
- First, the SBT changes that we made for Play do not work with Lagom, although I have an experimental version that will work with Lagom.
- Second, there could be more than one Lagom projects on the same build and rebuilding on the same JVM, which makes it all break down when some of the projects have Kamon and the others not.. which is for example, something that you have in the example you shared. Maybe the solution for this would be something at a higher level, like, having a different way to add Kamon to Lagom projects, but we are still figuring out what would be the way there :(
I noticed that you added an old dependency there, but that won't work with Kamon 2.x
if you need to, you can create either a MetricReporter or SpanReporter implementation and add it to Kamon using
Kamon.registerModule(...)
and in your custom reporter you can decide how to log the data that you want to see in the logs
Hmm I struggle with the kamon-akka-http operation name mappings. They cannot be configured as described in the example...
I went ahead and added the config example in the original kamon-akka-http project as described and then all tests fail the same way... Am I missing something or did this never work as described?
com.typesafe.config.ConfigException$BadPath: path parameter: Invalid path '/events//rsvps': Token not allowed in path expression: '' (Reserved character '*' is not allowed outside quotes) (you can double-quote this token if you really want it here)
Basically typesafe-config can load the example config so the exception is missleading.
I openend kamon-io/kamon-akka-http#72 with the example to reproduce this.

I am asking this because in the status page(kamon-status-page) the 'Akka Remote Instrumentation' module is disabled. I added the akka-remote at rc2 version, but still no update
Hi @leon-daniel , yes,
Having said that, if you run it with latest bundle, it should pick up automatically both akka and akka remote
kamon-akka-remote has been merged into kamon-akka repo (theres a notice here https://github.com/kamon-io/kamon-akka-remote ).Having said that, if you run it with latest bundle, it should pick up automatically both akka and akka remote
I looked over the tracing module and I saw I can add data to an operation being sent as a span, but nothing for metrics
and expose metric data, not tracing data
for now what I can see in prometheus as tag are component, interface ,port and http.status_code for some
PS: I don't see that in documentation either
It is a bit confusing to find tags being applied to spans and in the same time appear in metrics too
I thought the metrics and the tracing APIs don't mix(share data/tag)
Found the mistery. Apparently if there is endpoint called, the tags are not added :)
After calling some routes in my app, span related metrics appeared:
span_processing_time_seconds_bucket{operation="/discount",span_kind="server",http_status_code="200",error="false",le="0.005",component="akka.http.server",http_method="POST"} 0.0
Hi team! I'm trying to run a simple akka http application, with Kanela agent as the java agent attached to the docker images. When run my docker image though, I get
Exception in thread "main" java.lang.NoClassDefFoundError: akka/http/scaladsl/server/Directive$SingleValueTransformers$

at kamon.instrumentation.akka.http.PathDirectivesRawPathPrefixInterceptor.rawPathPrefix(AkkaHttpServerInstrumentation.scala)
at akka.http.scaladsl.server.directives.PathDirectives.rawPathPrefix(PathDirectives.scala) - any ideas what I am missing please?
