-Using the Embedded Metric Format, you will be able to visualize and alarm on custom metrics, but also retain the original, detailed and high-cardinality context which is queryable using [CloudWatch Logs Insights](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/AnalyzingLogData.html). For example, the library automatically injects environment metadata such as Lambda Function version, EC2 instance and image ids into the structured log event data.

 **LogStreamName**: For agent-based platforms, you may optionally configure the destination log stream that metrics should be delivered to.
