Amazon ElastiCache for Valkey now supports OpenTelemetry metrics and detailed monitoring

Amazon ElastiCache for Valkey

Amazon ElastiCache for Valkey now publishes OpenTelemetry metrics to Amazon CloudWatch for node-based clusters. Each metric carries attributes that can be filtered and aggregated using Prometheus Query Language (PromQL) expressions.

ElastiCache offers two monitoring modes:

• Standard monitoring: Publishes CloudWatch Metrics (Classic) every 60 seconds and a core set of OpenTelemetry metrics at the same interval at no additional charge.
• Detailed monitoring: Allows selection from the full set of OpenTelemetry metrics and publishes them every 15 seconds.

With OpenTelemetry metrics, you can detect nodes nearing their connection limit, break down errors by type during an incident, or forecast memory shortages. These queries can be run in CloudWatch and Grafana, leveraging your team's existing PromQL skills.

What to do

• Open the Metrics tab for a cluster in the Amazon ElastiCache console.
• Select Detailed and choose Configure detailed metrics.

OpenTelemetry metrics and detailed monitoring are available for node-based Valkey clusters in all AWS Regions where Amazon CloudWatch supports OpenTelemetry metrics. There is no additional charge from ElastiCache for detailed monitoring.

CloudWatch pricing for OpenTelemetry metrics applies to the detailed monitoring metrics you select, alarms you create, and PromQL API queries you run.
