Conclusion

Congratulations on finishing the Lambda Tracing Workshop! You have seen how we can complement auto-instrumentation with manual steps to have the producer-lambda function’s context be sent to the consumer-lambda function via a record in a Kinesis stream. This allowed us to build the expected Distributed Trace, and to contextualize the relationship between both functions in Splunk APM.

You can now build out a trace manually by linking two different functions together. This comes in handy when your auto-instrumentation, or 3rd-party systems, do not support context propagation out of the box, or when you wish to add custom attributes to a trace for more relevant trace analaysis.
