Chapter 4. Configuring power monitoring

Procedure

1. In the Administrator perspective of the web console, click Operators Installed Operators.
2. Click Power monitoring for Red Hat OpenShift from the Installed Operators list and click the Kepler tab.
3. Click Create Kepler. If you already have a Kepler instance created, click Edit Kepler.

4. Configure .spec.exporter.redfish of the Kepler instance by specifying the mandatory secretRef field. You can also configure the optional probeInterval and skipSSLVerify fields to meet your needs.

   Example Kepler instance

   apiVersion: kepler.system.sustainable.computing.io/v1alpha1
   kind: Kepler
   metadata:
     name: kepler
   spec:
     exporter:
       deployment:
   # ...
       redfish:
         secretRef: <secret_name> required 1
         probeInterval: 60s 2
         skipSSLVerify: false 3
   # ...

   1

   Required: Specifies the name of the secret that contains the credentials for accessing the Redfish server.

   2

   Optional: Controls the frequency at which the power information is queried from Redfish. The default value is 60s.

   3

   Optional: Controls if Kepler skips verifying the Redfish server certificate. The default value is false.

   Note

   After Kepler is deployed, the openshift-power-monitoring namespace is created.

5. Create the redfish.csv file with the following data format:

   <your_kubelet_node_name>,<redfish_username>,<redfish_password>,https://<redfish_ip_or_hostname>/

   Example redfish.csv file

   control-plane,exampleuser,examplepass,https://redfish.nodes.example.com
   worker-1,exampleuser,examplepass,https://redfish.nodes.example.com
   worker-2,exampleuser,examplepass,https://another.redfish.nodes.example.com

6. Create the secret under the openshift-power-monitoring namespace. You must create the secret with the following conditions:

   • The secret type is Opaque.
   • The credentials are stored under the redfish.csv key in the data field of the secret.

   $ oc -n openshift-power-monitoring \
         create secret generic redfish-secret \
         --from-file=redfish.csv

   Example output

   apiVersion: v1
   kind: Secret
   metadata:
     name: redfish-secret
   data:
     redfish.csv: YmFyCg==
     # ...

   Important

   The Kepler deployment will not continue until the Redfish secret is created. You can find this information in the status of a Kepler instance.
