      Request for sending data via telemetry

      The goal is to collect metrics about CSI migration on vSphere because we're adding an explicit opt-in in 4.13 and we want to know how many clusters actually opted in.


      cluster:vsphere_csi_migration:max shows if CSI migration for vSphere was enabled or not or explicitly disabled.


      • status, possible values are "", LegacyDeprecatedInTreeDriver and CSIWithMigrationDriver

      We basically send value of Storage CRD vsphereStorageDriver field to see what customers use. See https://github.com/openshift/api/pull/1433 for the field definition, it has 3 allowed values.

      The cardinality of the metric is at most 3.

      See https://github.com/openshift/cluster-monitoring-operator/pull/1929/ for related PR.

      Additional info

      This is a last-minute addition to 4.13 and to 4.13 only. We won't have such metric in 4.14, because CSI migration will be forced "on" and no field can override it. We know we're breaking some rules, please reach to our staff engineer bbennett@redhat.com with additional questions.
