Casting light on (Bare) Metal: Meet the Ironic Prometheus Exporter!

  • Presented by Iury Gregory Melo Ferreira from Red Hat
  • What can you expect to learn?
    • Baseboard Management Controllers (BMCs) can provide useful monitoring data about physical nodes. This information is beneficial to operators, allowing them to detect issues and take actions when something is wrong (e.g., High temperatures can cause unexpected node shutdowns and you can define different alerts). With the Train release a new way to use this data was born, please welcome the Ironic Prometheus Exporter (IPE)!
    • Ironic builds upon the principles of open source and open standards to enable support for a diverse ecosystem of hardware from a variety of vendors. By using the IPE, you will have multiple metrics for each physical node (e.g., temperature, power) available on Prometheus, as long as the vendor supports IPMI or Redfish protocol.
    • During the session, we will show how to configure IPE, share advantages & limitations, show a demo of how to monitor different physical nodes, and what operators can achieve when using it and close with our plans for further improvements.
