aws-otel-lambda VS zipkin-api-example

OpenTelemetry is being pushed as a replacement for AWS X-Ray SDKs by AWS, but it's in such a broken state for Lambda right now. A 200-500% performance penalty for using it is insane[1][2].

The documentation for Lambda gives example code for the different languages. To shorten the long way from example code to running code, I will show you ready-to-run CDK code for Python, Node and GO with a serverless architecture. With Lambda, we are using the AWS X-Ray exporter in the collector. If you want to build your own layer, clone the repo AWS-managed OpenTelemetry Lambda Layers. To do that, learn GO here. You might know the creator of the site 😉 .

Sorry you're having trouble working with the ADOT Lambda Layers :(. Have you had a chance to open an issue on the GitHub repo for OTel Lambda or ADOT Lambda? You should add your expected vs your actual output!

Shimmer is a monkeypatching library that a telemetry extension for AWS Lambda was using.

Yes, I really agree, and I've gone through the same pain, but try using the alternatives that claim to be better because they have OpenAPI specifications [1]

The example shows you how to use the swagger tool, parse the OpenAPI spec [2], auto-generate GoLang glue code, call __one__ of those auto-generated functions and log a trace.

However, there is zero documentation, zero other examples, and I'm left scratching my head whether there's even one person in the world using this approach. I eventually ended up just directly using the service APIs [3] via REST calls.

OTEL is painful, but the alternatives are no better :( I really wish there's some interest in this space, since SLO's and SLI measurements are becoming increasingly important.
