# MQTT Consumer Input Plugin
 | 
						|
 | 
						|
The [MQTT](http://mqtt.org/) consumer plugin reads from
 | 
						|
specified MQTT topics and adds messages to InfluxDB.
 | 
						|
The plugin expects messages in the
 | 
						|
[Telegraf Input Data Formats](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md).
 | 
						|
 | 
						|
### Configuration:
 | 
						|
 | 
						|
```toml
 | 
						|
# Read metrics from MQTT topic(s)
 | 
						|
[[inputs.mqtt_consumer]]
 | 
						|
  ## MQTT broker URLs to be used. The format should be scheme://host:port,
 | 
						|
  ## schema can be tcp, ssl, or ws.
 | 
						|
  servers = ["tcp://localhost:1883"]
 | 
						|
  ## MQTT QoS, must be 0, 1, or 2
 | 
						|
  qos = 0
 | 
						|
  ## Connection timeout for initial connection in seconds
 | 
						|
  connection_timeout = "30s"
 | 
						|
 | 
						|
  ## Topics to subscribe to
 | 
						|
  topics = [
 | 
						|
    "telegraf/host01/cpu",
 | 
						|
    "telegraf/+/mem",
 | 
						|
    "sensors/#",
 | 
						|
  ]
 | 
						|
 | 
						|
  # if true, messages that can't be delivered while the subscriber is offline
 | 
						|
  # will be delivered when it comes back (such as on service restart).
 | 
						|
  # NOTE: if true, client_id MUST be set
 | 
						|
  persistent_session = false
 | 
						|
  # If empty, a random client ID will be generated.
 | 
						|
  client_id = ""
 | 
						|
 | 
						|
  ## username and password to connect MQTT server.
 | 
						|
  # username = "telegraf"
 | 
						|
  # password = "metricsmetricsmetricsmetrics"
 | 
						|
 | 
						|
  ## Optional TLS Config
 | 
						|
  # tls_ca = "/etc/telegraf/ca.pem"
 | 
						|
  # tls_cert = "/etc/telegraf/cert.pem"
 | 
						|
  # tls_key = "/etc/telegraf/key.pem"
 | 
						|
  ## Use TLS but skip chain & host verification
 | 
						|
  # insecure_skip_verify = false
 | 
						|
 | 
						|
  ## Data format to consume.
 | 
						|
  ## Each data format has its own unique set of configuration options, read
 | 
						|
  ## more about them here:
 | 
						|
  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
 | 
						|
  data_format = "influx"
 | 
						|
```
 | 
						|
 | 
						|
### Tags:
 | 
						|
 | 
						|
- All measurements are tagged with the incoming topic, ie
 | 
						|
`topic=telegraf/host01/cpu`
