The authentication flow is similar to that of OpenID, however the token is "opaque" to MinIO - it is simply sent to the plugin for verification. CAVEAT: There is no console UI integration for this method of authentication and it is intended primarily for machine authentication.

It can be configured via MinIO's standard configuration API (i.e. using `mc admin config set/get`), or equivalently with environment variables. For brevity we show only environment variables here:

	audit := logger.CurrentStats()
	for id, st := range audit {
		labels := []string{targetID, id}
		m.Set(auditFailedMessages, float64(st.FailedMessages), labels...)
		m.Set(auditTargetQueueLength, float64(st.QueueLength), labels...)
		m.Set(auditTotalMessages, float64(st.TotalMessages), labels...)
	}

	return nil
