Upgrading metering

You can upgrade metering to 4.4 by updating the Metering Operator subscription.

Upgrading the Metering Operator is supported for OpenShift Container Platform 4.4.13 and later.

Prerequisites

  • The cluster is updated to 4.4.

  • The Metering Operator is installed from OperatorHub.

    You must upgrade the Metering Operator to 4.4 manually. Metering does not upgrade automatically if you selected the "Automatic" Approval Strategy in a previous installation.

  • The MeteringConfig is configured.

  • The metering stack is installed.

  • Ensure that metering status is healthy by checking that all Pods are ready.

Potential data loss can occur if you modify your metering storage configuration after installing or upgrading metering.
Procedure

  1. Click Operators → Installed Operators from the web console.

  2. Select the openshift-metering project.

  3. Click Metering Operator.

  4. Click Subscription → Channel.

  5. In the Change Subscription Update Channel window, select 4.4 and click Save.

    Wait several seconds to allow the subscription to update before proceeding to the next step.

  6. Click Operators → Installed Operators.

    The Metering Operator is shown as 4.4. For example:

    Metering
4.4.0-202007012112.p0 provided by Red Hat, Inc
Verification

You can verify the metering upgrade by performing any of the following checks:

  • Check the Metering Operator ClusterServiceVersion (CSV) for the new metering version. This can be done through either the web console or CLI.

    Procedure (UI)

    1. Navigate to Operators → Installed Operators in the metering namespace.

    2. Click Metering Operator.

    3. Click Subscription for Subscription Details.

    4. Check the Installed Version for the upgraded metering version. The Starting Version shows the metering version prior to upgrading.

    Procedure (CLI)

    • Check the Metering Operator CSV:

      $ oc get csv | grep metering

      In the following example, the 4.4 Metering Operator upgrade is successful and replaces the 4.3 metering installation:

      NAME                                        DISPLAY                  VERSION                 REPLACES                               PHASE
metering-operator.4.4.0-202007012112.p0     Metering                 4.4.0-202007012112.p0   metering-operator.4.3.0-202005252114   Succeeded

  • Check that all required Pods in the openshift-metering namespace are created. This can be done through either the web console or CLI.

    Many Pods rely on other components to function before they themselves can be considered ready. Some Pods may restart if other Pods take too long to start. This is to be expected during the Metering Operator upgrade.
    Procedure (UI)

    • Navigate to Workloads → Pods in the metering namespace and verify that Pods are being created. This can take several minutes after upgrading the metering stack.

    Procedure (CLI)

    • Check that all required Pods in the openshift-metering namespace are created:

      $ oc -n openshift-metering get pods

      The output shows that all Pods are created in the Ready column:

      NAME                                  READY   STATUS    RESTARTS   AGE
hive-metastore-0                      2/2     Running   0          3m28s
hive-server-0                         3/3     Running   0          3m28s
metering-operator-68dd64cfb6-2k7d9    2/2     Running   0          5m17s
presto-coordinator-0                  2/2     Running   0          3m9s
reporting-operator-5588964bf8-x2tkn   2/2     Running   0          2m40s

  • Verify that the ReportDataSources are importing new data, indicated by a valid timestamp in the NEWEST METRIC column. This might take several minutes. Filter out the "-raw" ReportDataSources, which do not import data:

    $ oc get reportdatasources -n openshift-metering | grep -v raw

    Timestamps in the NEWEST METRIC column indicate that ReportDataSources are beginning to import new data:

    NAME                                         EARLIEST METRIC        NEWEST METRIC          IMPORT START           IMPORT END             LAST IMPORT TIME       AGE

After all Pods are ready and you have verified that new data is being imported, metering continues to collect data and report on your cluster. Review a previously scheduled Report or create a Run-Once metering Report to confirm the metering upgrade.
