# Variant A: Direct scrape of Newt (/metrics) via Prometheus (no Collector needed)
# Note: Newt already exposes labels like site_id, protocol, direction. Do not promote
# resource attributes into labels when scraping Newt directly.
#
# Example Prometheus scrape config:
# global:
#   scrape_interval: 15s
# scrape_configs:
#   - job_name: newt
#     static_configs:
#       - targets: ["newt:2112"]
#
# Variant B: Use OTEL Collector (Newt -> OTLP -> Collector -> Prometheus)
# This pipeline scrapes metrics from the Collector's Prometheus exporter.
# Labels are already on datapoints; promotion from resource is OPTIONAL and typically NOT required.
# If you enable transform/promote below, ensure you do not duplicate labels.
