kamon can not work with datadog agent

[uname-yang]

Hi
we use kamon and datadog together. but it conflict with datadog agent from version 0.55.
is there any way to solve this ?

thanks

Hi @uname-yang, are you using the kamon bundle? can you try adding the kanela agent jar to the jvm params like -J-javaagent:dd-java-agent.jar -J-javaagent:kanela-agent.jar?

[uname-yang]

still not work by using jvm opts

[dpsoft]

@uname-yang only for double check:

• if you run only with kanela, works?
• if you change the order of execution of the agent like: kanela then dd or dd then kanela, works?

Also you can add kanela.debug-mode = true in your application.config in order to get more information over the instrumentation process.

@ivantopo any thoughts?

[uname-yang]

@dpsoft thanks for checking:

1. we can run only with kanela. It works.
2. it's no different when exchange the order.

attach the log here

I guess there must be some common lib using by dd and kamon , such as bytebuddy, only can be applied once.

@uname-yang can you try disabling okhttp instrumentation -> kanela.modules.okhttp-module.enabled=false? I think kanela is trying to instrument the okhttp client inside of dd-agent. An in a second try you can comment //Kamon.init() and pass the agent as JVM argument.

Thanks in advance.

@dpsoft i check the source code. It seems okhhttp-module does not have enabled flag.
Here is the error log when start app as your suggestion, same as before:

[dpsoft]

@uname-yang all kanela modules inherit the module configuration with some default values described in kanela [configuration]. Can you try adding

kanela {
   debug-mode = true
   log-level = "DEBUG"
   modules.okhttp-module.enabled = false
}
 
and share the log with us?

Hi @uname-yang @stewart-shawn, any chance to make a minimal executable example to play with and try to reproduce the problem?

[stewart-shawn]

@dpsoft No problem. I've added an example here: https://github.com/stewart-shawn/dd-kamon-demo. Thanks for checking into this
