+# Read metrics from MQTT topic(s)
+[[inputs.mqtt_consumer]]
+  ## Broker URLs for the MQTT server or cluster.  To connect to multiple
+  ## clusters or standalone servers, use a separate plugin instance.
+  ##   example: servers = ["tcp://localhost:1883"]
+  ##            servers = ["ssl://localhost:1883"]
+  ##            servers = ["ws://localhost:1883"]
+  servers = ["tcp://127.0.0.1:1883"]
+
+  ## Topics that will be subscribed to.
+  topics = [
+    "telegraf/host01/cpu",
+    "telegraf/+/mem",
+    "sensors/#",
+  ]
+
+  ## The message topic will be stored in a tag specified by this value.  If set
+  ## to the empty string no topic tag will be created.
+  # topic_tag = "topic"
+
+  ## QoS policy for messages
+  ##   0 = at most once
+  ##   1 = at least once
+  ##   2 = exactly once
+  ##
+  ## When using a QoS of 1 or 2, you should enable persistent_session to allow
+  ## resuming unacknowledged messages.
+  # qos = 0
+
+  ## Connection timeout for initial connection in seconds
+  # connection_timeout = "30s"
+
+  ## Interval and ping timeout for keep-alive messages
+  ## The sum of those options defines when a connection loss is detected.
+  ## Note: The keep-alive interval needs to be greater or equal one second and
+  ## fractions of a second are not supported.
+  # keepalive = "60s"
+  # ping_timeout = "10s"
+
+  ## Max undelivered messages
+  ## This plugin uses tracking metrics, which ensure messages are read to
+  ## outputs before acknowledging them to the original broker to ensure data
+  ## is not lost. This option sets the maximum messages to read from the
+  ## broker that have not been written by an output.
+  ##
+  ## This value needs to be picked with awareness of the agent's
+  ## metric_batch_size value as well. Setting max undelivered messages too high
+  ## can result in a constant stream of data batches to the output. While
+  ## setting it too low may never flush the broker's messages.
+  # max_undelivered_messages = 1000
+
+  ## Persistent session disables clearing of the client session on connection.
+  ## In order for this option to work you must also set client_id to identify
+  ## the client.  To receive messages that arrived while the client is offline,
+  ## also set the qos option to 1 or 2 and don't forget to also set the QoS when
+  ## publishing. Finally, using a persistent session will use the initial
+  ## connection topics and not subscribe to any new topics even after
+  ## reconnecting or restarting without a change in client ID.
+  # persistent_session = false
+
+  ## If unset, 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
+
+  ## Client trace messages
+  ## When set to true, and debug mode enabled in the agent settings, the MQTT
+  ## client's messages are included in telegraf logs. These messages are very
+  ## noisey, but essential for debugging issues.
+  # client_trace = 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"
+
+  ## Enable extracting tag values from MQTT topics
+  ## _ denotes an ignored entry in the topic path,
+  ## # denotes a variable length path element (can only be used once per setting)
