## Publish MinIO events MQTT

Install an MQTT Broker from [here](https://mosquitto.org/).

### Step 1: Add MQTT endpoint to MinIO

The MQTT configuration is located as `notify_mqtt` key. Create a configuration key-value pair here for your MQTT instance. The key is a name for your MQTT endpoint, and the value is a collection of key-value parameters described in the table below.

			Key:         target.MqttBroker,
			Description: "MQTT server endpoint e.g. `tcp://localhost:1883`",
			Type:        "uri",
			Sensitive:   true,
		},
		config.HelpKV{
			Key:         target.MqttTopic,
			Description: "name of the MQTT topic to publish",
			Type:        "string",
		},
		config.HelpKV{
			Key:         target.MqttUsername,
			Description: "MQTT username",
			Optional:    true,

}

// ConsoleLogger is introduced to workaround the dependency about logrus
type ConsoleLogger struct {
	Enable bool `json:"enable"`
}

// serverConfigV33 is just like version '32', removes clientID from NATS and MQTT, and adds queueDir, queueLimit in all notification targets.
type serverConfigV33 struct {
	quick.Config `json:"-"` // ignore interfaces

	Version string `json:"version"`

	// S3 API configuration.
