| APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and might reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources |
|
| Kind is a string value representing the REST resource this object represents. Servers might infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds |

FlowMetricSpec defines the desired state of FlowMetric The provided API allows you to customize these metrics according to your needs.
When adding new metrics or modifying existing labels, you must carefully monitor the memory usage of Prometheus workloads as this could potentially have a high impact. Cf https://rhobs-handbook.netlify.app/products/openshiftmonitoring/telemetry.md/#what-is-the-cardinality-of-a-metric
