Amazon CloudWatch Introduces OpenTelemetry and PromQL Support
Key point
Amazon CloudWatch has launched general availability of OpenTelemetry metrics ingestion and PromQL query support, strengthening observability.
Details
Amazon CloudWatch has achieved general availability (GA) for native ingestion of OpenTelemetry (OTel) metrics and PromQL support. This enables direct collection and management of high-dimensional metrics from Kubernetes and microservices environments without conversion.
The key features of this update are as follows:
- High Cardinality Support: Supports up to 150 labels per metric, exceeding the previous 30-dimension limit to enable detailed storage of metrics from complex container and application environments.
- PromQL Query Support: Users familiar with Prometheus can use PromQL to instantly query infrastructure and AWS resource metrics in CloudWatch and Amazon Managed Grafana.
- Automatic AWS Resource Enrichment: AWS context such as account ID, region, cluster ARN, and resource tags is automatically added to all collected metrics, enabling sophisticated filtering and grouping without additional configuration.
Additionally, Telemetry Pipelines that perform routing and transformation before storing metrics, cross-account centralization that aggregates metrics across multiple accounts, and Bearer token authentication are also provided together.
