Casting light on (Bare) Metal: Meet the Ironic Prometheus Exporter!
summary
Ironic Prometheus Exporter (introduced in OpenStack Train) converts BMC sensor pulls into Prometheus text files per node so Prometheus scrapes temperature, power, fan rpm and similar metrics on a 10–600s cadence; a demo with a Dell R640 (IPMI) and an HPE DL380 Gen10 (Redfish) shows 93–158 metric lines per node and a triggered dual power‑supply alert that reached Alertmanager and Grafana. Required config: sensor_store_data=true, sensor_data_interval (default 600s), and a storage location; current limits: gauges only and tested with IPMI/Redfish.
