Reactivemongo Integration

The kamon-mongo module brings bytecode instrumentation to trace the reactivemongo library

The kamon-mongo module requires you to start your application using the AspectJ Weaver Agent. Kamon will warn you at startup if you failed to do so.

The bytecode instrumentation provided by the kamon-mongo module hooks into the reactivemongo code to automatically start and finish spans for requests. This translates into you having traces about how the requests you are doing are behaving.

Getting Started

Kamon scala module is currently available for Scala 2.11 and 2.12.

Supported releases and dependencies are shown below.

kamon-mongo	reactivemongo	status	jdk	scala
0.0.4	0.12 until 0.16	stable	1.8+	2.11, 2.12

To get started with SBT, simply add the following to your build.sbt file:

resolvers += "jitpack" at "https://jitpack.io"
libraryDependencies += "com.github.jtjeferreira" %% "kamon-mongo" % "0.0.4"

Naming Segments

By default, the name generator bundled with the kamon-mongo module will use the collection name as the name to the automatically generated segment. Currently, the only way to override that name would be to provide your own implementation of kamon.mongo.NameGenerator which is used to assign the segment name

Configuration

kamon {
  mongo {
    # Fully qualified name of the implementation of kamon.mongo.NameGenerator that will be used for assigning names to segments.
    name-generator = kamon.mongo.DefaultNameGenerator
  }
}
