To enable network policy for MinIO,
install [a networking plugin that implements the Kubernetes
NetworkPolicy spec](https://kubernetes.io/docs/tasks/administer-cluster/declare-network-policy#before-you-begin),
and set `networkPolicy.enabled` to `true`.

			prometheus.CounterValue,

// and sends to given channel
