kamon.instrumentation.akka.http

Tracks the last operation name that was automatically assigned to an operation via instrumentation. The instrumentation might assign a name to the operations via settings on the HTTP Server instrumentation instance or via the Path directives instrumentation, but might never reassign a name if the user somehow assigned their own name to the operation. Users chan change operation names by:

• Using operation mappings via configuration of the HTTP Server.
• Providing a custom HTTP Operation Name Generator for the server.
• Using the "operationName" directive.
• Directly accessing the Span for the current operation and changing the name on it.

Wraps a Flow[HttpRequest,HttpResponse] with the necessary infrastructure to provide HTTP Server metrics, tracing and Context propagation.
