Originally created by @hooverdc here. I wasn't able to move the issue so creating a new one and linking.

Describe your idea/feature/enhancement

I wish SAM CLI would support the Lambda Telemetry API

Proposal

Provide a mock endpoint similar to the Lambda Logs API in the Lambda runtime images.

SAM CLI would need support in RIE to make this achievable within the emulation images.

Just a +1 here. It would be great to have this. Right now, our SAM Local invoke won't work if we have OpenTelemetry in use by our Lambdas.

A lot of other folks are dealing with this. See here: https://github.com/aws/aws-sam-cli/issues/4570

Looks like it's not possible to use Localstack as a workaround either: https://github.com/localstack/localstack/issues/9617

I've had to emulate the telemetry API myself in order to properly execute our Lambda Extension, which is fine – but first-class support for something so crucial to the ecosystem would be warmly welcomed by the community.

+1, this causes DataDog's lambda extension to hang indefinitely. I could potentially write conditional code to only run it when not running locally, but that kind of defeats the point of sam's local support. https://github.com/DataDog/datadog-lambda-go/issues/176
