YACE is a Prometheus exporter for AWS CloudWatch that auto-discovers resources through AWS tags and exposes their metrics with AWS tags as labels.
Yet Another CloudWatch Exporter (YACE) is a Prometheus exporter for AWS CloudWatch metrics, written in Go using the official AWS SDK. It automatically discovers AWS resources via tags across more than 100 supported services — including EC2, RDS, Lambda, ELB, and many more — and exposes their CloudWatch metrics as Prometheus metrics with AWS resource tags and CloudWatch dimensions added as labels. YACE supports cross-account scraping via IAM role assumption and can pull static metrics for namespaces that do not support tag-based auto-discovery.
YACE joined the Prometheus community organization in November 2024. For full configuration reference and installation guides, see the upstream project documentation.
