Measuring a request

[kaihendry]

Sorry, I have two questions RE AWS EMF and this library:

1. Why isn't it part of the AWS JS SDK?

2. Use case: Measure a fetch. Lambda functions typically depend on external services and I am wondering if EMF logging is a good approach to tracking the performance of these dependencies. Or is that best left to some AWS X-ray instrumentation?

I've fleshed out an example here: https://github.com/kaihendry/yt-aws-emf/blob/main/hello-world/app.js

I'm still confused how to best capture in a metric:

• http status code
• duration

I ended up doing something like: https://stackoverflow.com/a/69535668/4534

If it can be better, please let me know!
