Prometheus + Grafana

# Live metrics in Prometheus + Grafana — Artillery's
# `prometheus-grafana-dashboards`.
#
# loadr exposes a Prometheus scrape endpoint while the test runs; Prometheus
# scrapes it (see prometheus.yml) and Grafana graphs it (grafana-dashboard.json).
# For a push model instead, drop `listen` and set `remote_write_url:`.
#
#   docker compose -f examples/prometheus-grafana/docker-compose.yml up -d
#   loadr run examples/prometheus-grafana/loadr.yaml
#   # Grafana: http://localhost:3000  (import grafana-dashboard.json)
