I have the need to run client-side monitoring for AWS Lambda functions, but haven't managed to figure out yet what's the easiest option to do so. While I could point AWS_CSM_HOST to some external IP-address, the lack of encryption and authentication makes that pretty nonviable. Alternatively I could put the AWS Lambda functions into VPC, but I'd prefer a less invasive change to the AWS Lambda functions. Does somebody here have a better solution for that?
