How can I optimize costs associated with publishing Lambda custom metrics to CloudWatch?

Question

I'm concerned about the costs associated with publishing custom metrics to Amazon CloudWatch. I want to create a report out of these metrics. Is there an alternative option that I can explore? I suppose there is an option to send AWS Lambda logs to CloudWatch and use the Lambda Insights, or create a report from the Amazon S3 bucket. I'm not sure if it's a best practice.

You can use the [CloudWatch embedded metric format][1]. The embedded metric format sends the metrics to CloudWatch Logs through log messages. These messages are automatically pushed to CloudWatch metrics.

You can also consider using the AWS Lambda Power Tools for [Python][2] or [Java][3].
