Configuration

To enable the ironic-prometheus-exporter to collect the sensor data from Ironic, it’s necessary to enable some configuration parameters in the ironic.conf. Below you can see an example of the required configuration, the table Configuration options for the ironic-prometheus-exporter in Ironic shows all the available configuration options.

Example of configuration

[conductor]
send_sensor_data = true
send_sensor_data_interval = 300

[oslo_messaging_notifications]
driver = prometheus_exporter
transport_url = fake://
location = /opt/stack/node_metrics
