Kamon's integration with Akka comes in the form of two modules:
kamon-akka-remote that bring bytecode
instrumentation to gather metrics and perform automatic
TraceContext propagation on your behalf.
The kamon-akka module require you to start your application using the AspectJ Weaver Agent. Kamon will warn you at startup if you failed to do so.
Here is a quick list of the functionalities included on each module:
- Actor, Router and Dispatcher Metrics: This module hooks into Akka's heart to give you a robust set of metrics based on the concepts already exposed by our metrics module.
- Automatic TraceContext Propagation: This allows you to implicitly propagate the
TraceContextacross actor messages without having to change a single line of code and respecting the "follow the events" rather than "stick to the thread" convention as described in the event based threading model section.
- Ask Pattern Timeout Warning: A utility that logs a warning with additional information when a usage of the Ask Pattern timesout.
