Current Series Release Notes¶

4.9.0-1¶

Fixed a crash (TypeError: unsupported operand type(s) for +: 'NoneType' and 'str') in PrometheusFileDriver when Ironic emitted versioned notifications such as NodeSetPowerStatePayload. The driver is registered as an oslo.messaging notification driver and therefore receives every notification Ironic emits, not only sensor data. Versioned notifications carry a versioned object payload with no node_name, node_uuid, or hostname field, which made the driver fail while building the output file name.

The driver now only processes metrics notifications, meaning the conductor metrics event type (ironic.metrics) and node sensor data event types (hardware.<hardware type>.metrics, which Ironic builds from the node’s hardware type). All other notifications are ignored. Node sensor notifications for hardware types without a dedicated parser continue to export the baremetal_last_payload_timestamp_seconds metric as before. See bug 2166070.
