We have set up an AWS Cloudwatch metrics stream to send metrics to NR for our AWS services. Then we looked at instrumenting Lambda functions, which appears to depend on the (polling based) AWS Lambda integration. Once that was enabled, lots of metrics and functions were duplicated
To resolve this, I have excluded Lambda namespace from the cloudwatch metrics stream. Is this the right approach? Do we have to go back to polling cloudwatch metrics to be able to have in-depth lambda monitoring?
