- Add statsd-exporter service to docker-compose.yml (prom/statsd-exporter:v0.27.1) - Add StatsD env vars to airflow-default-env for metrics export - Add airflow job to prometheus.yml scrape configs - Add Airflow Overview dashboard (Grafana provisioning) - Add Airflow alert rules: scheduler down, queue backlog, failures, parse time - Add configs/statsd_mapping.yml for StatsD → Prometheus conversion - Use Prometheus naming convention (_total for counters, _seconds for timers) - Add monitoring plan at plans/monitoring_airflow_plan.md - Update OPERATIONS.md and Makefile for airflow monitoring Tested: all 3 jobs (airflow, clickhouse, kafka) showing UP in Prometheus, metrics flowing (dagbag_size=3, executor slots, heartbeats with _total suffix), all 4 alert rules loaded in Grafana
