# Sample scrape config for CloudWatch managed Prometheus collector (EC2 Node Exporter)
# Context: Prometheus scrape YAML for CreateScraper configurationBlob (base64-encode before API call).
# Assumed setup: Node Exporter on port 9100; private DNS names; us-east-1 VPC; 30s scrape.
# Docs: https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Solution-Prometheus-On-EC2.html
#
# Replace targets with your instance private DNS names or IPs.
# Keep metric_relabel_configs aggressive — cardinality is the bill.
