- By default kamon spreads the trace-token-header-name, but sometimes is necessary pass through the application requests with some information like
- extra headers, with kamon it's possible using the TraceLocalStorage, in Play applications we can do an Action Filter or using Action Composition,
- in this example we are using a simple filter where given a Header store the value and then put the value in the result headers..
-
- More detailed usage of TraceLocalStorage: https://github.com/kamon-io/Kamon/blob/b17539d231da923ea854c01d2c69eb02ef1e85b1/kamon-core/src/test/scala/kamon/trace/TraceLocalSpec.scala
