This article explains how to use metric name filters in Amazon CloudWatch Metric Streams for granular control over streamed metrics.

• Metric name filtering enables Include or Exclude filters for specific metrics within namespaces
• Include filters provide exact metric selection but require manual maintenance of metric lists
• Exclude filters automatically receive new metrics and require shorter exclusion lists
• Filters can be created on metrics that don't yet exist in your AWS account
• Metric name filtering reduces costs by controlling quantity of metric stream updates egressed
• Console walkthrough demonstrates creating streams with Include and Exclude filters
• CloudFormation templates provided for programmatic metric stream creation
• Metric Streams automatically creates S3 bucket, IAM roles, and Kinesis Firehose resources

CloudWatch Metric Streams now provides enhanced filtering capabilities for precise control over metric streaming to destinations, reducing operational overhead and costs.
