# ADOT (AWS Distro for OpenTelemetry) Collector config — dual-export reference
#
# Pattern: instrument once with OpenTelemetry, send TRACES to CloudWatch
# Application Signals / X-Ray (for the service map + SLOs) and METRICS to
# Amazon Managed Service for Prometheus (for PromQL + high-cardinality infra).
# This keeps instrumentation vendor-portable while using each backend for what
# it is best at.
#
# Setup assumed: ADOT Collector v0.40+ running as a sidecar/daemonset with an
# IAM role allowing aps:RemoteWrite to your AMP workspace and X-Ray write.
# Verify exporter names against the ADOT release you deploy - exporter configs
# change across versions.
