How to publish FROM an AWS lambda to a cloud watch metric in Node.js

Question

Inside a lambda I use to periodically check in on a service I check the value of the result from the server and I want that value published to AWS cloudwatch as a metric to form

Answer 1

if you want to avoid the latency impact that introducing a sync cloudwatch call would introduce, you could use Metric Filters on the asynchronous logs that are being published.
