# Prometheus scrape config for Docker Dash's /api/metrics endpoint.
# Minimal — only scrapes the app and optionally Prometheus itself.
# For production-grade scrapes, add relabel_configs, recording rules,
# and alerting rules as needed.
#
# v7.1.0. Shipped as part of `docker compose --profile observability up -d`.

# v7.6.0 — Alert rule files. Loaded relative to this file; the docker-compose
