Amazon CloudWatch Pipelines Now Supports Processing and Enriching OpenTelemetry Metrics

Amazon CloudWatch has significantly enhanced its pipelines service by integrating support for processing and enriching OpenTelemetry (OTel) metrics directly during ingestion. This new functionality, announced on June 30, 2026, streamlines the management of telemetry data by allowing users to transform OTel metrics without the need for custom processing layers or altering application instrumentation at the source. Previously, organizations often had to build their own processing solutions or adjust their application code to modify OTel metrics before they were stored. With CloudWatch pipelines, these transformations can now be applied centrally as part of the ingestion path, eliminating the operational overhead of managing additional infrastructure like OTel Collectors or Lambda functions. The update provides several key benefits for users. For instance, it enables the enrichment of metrics with crucial business context, such as team ownership, cost centers, and environment tags, even for metrics from sources that cannot be directly modified. This is particularly useful for gaining deeper insights into operational performance and cost allocation. Furthermore, the service allows for the stripping of high-cardinality labels from custom workloads. This capability is vital for reducing storage costs associated with detailed, unique identifiers that might not be necessary for aggregate analysis. Users can also rename metrics and attributes to enforce consistent naming conventions across their entire organization, improving data clarity and standardization. These processing capabilities are applied transparently to matched metrics, meaning no changes are required to the application's instrumentation. The new OTel metric processing for CloudWatch pipelines is available in all AWS Regions where CloudWatch pipelines and native OpenTelemetry metrics are supported. Importantly, this processing is offered at no additional cost, with only the standard CloudWatch pricing for OTel metrics ingestion applying. To get started, users can access the Amazon CloudWatch console, navigate to 'pipelines' under 'Ingestion,' and select 'CloudWatch Metrics (OTel)' as the source. This integration simplifies the observability stack for AWS users, making it easier to manage, transform, and analyze OpenTelemetry metrics efficiently.
