Datadog has a similarhish project for instrumenting lambdas. (Ran into.it tbis week, though I was looking for something else, their Monitor cdk). Thought i'd mention this competitor. Would be interesting to try to do a more in depth compare & contrast.
This is one step away from being another example of a project with an awful name from AWS. If it was "AWS Lambda Powertools for TypeScript" they'd save it, but no.
