# Full-stack: exporter + Prometheus + Grafana with the GPON dashboard
# auto-provisioned. For users who don't already run their own observability
# infra. Bring up with:
#
#   cp .env.example .env   # then fill in ONU_SSH_PASSWORD
#   docker compose up -d
#
# Then open http://localhost:3000 (admin / admin by default, change via
# GRAFANA_ADMIN_PASSWORD in .env). The GPON dashboard is in the
# dashboards list on first login.
#
# If you ALREADY run Prometheus + Grafana, use docker-compose.exporter-only.yml
# instead and wire the exporter into your existing scrape config.
