+# Azure Event Hubs service input plugin
+[[inputs.eventhub_consumer]]
+  ## The default behavior is to create a new Event Hub client from environment variables.
+  ## This requires one of the following sets of environment variables to be set:
+  ##
+  ## 1) Expected Environment Variables:
+  ##    - "EVENTHUB_CONNECTION_STRING"
+  ##
+  ## 2) Expected Environment Variables:
+  ##    - "EVENTHUB_NAMESPACE"
+  ##    - "EVENTHUB_NAME"
+  ##    - "EVENTHUB_KEY_NAME"
+  ##    - "EVENTHUB_KEY_VALUE"
+
+  ## 3) Expected Environment Variables:
+  ##    - "EVENTHUB_NAMESPACE"
+  ##    - "EVENTHUB_NAME"
+  ##    - "AZURE_TENANT_ID"
+  ##    - "AZURE_CLIENT_ID"
+  ##    - "AZURE_CLIENT_SECRET"
+
+  ## Uncommenting the option below will create an Event Hub client based solely on the connection string.
+  ## This can either be the associated environment variable or hard coded directly.
+  ## If this option is uncommented, environment variables will be ignored.
+  ## Connection string should contain EventHubName (EntityPath)
+  # connection_string = ""
+
+  ## Set persistence directory to a valid folder to use a file persister instead of an in-memory persister
+  # persistence_dir = ""
+
+  ## Change the default consumer group
+  # consumer_group = ""
+
+  ## By default the event hub receives all messages present on the broker, alternative modes can be set below.
+  ## The timestamp should be in https://github.com/toml-lang/toml#offset-date-time format (RFC 3339).
+  ## The 3 options below only apply if no valid persister is read from memory or file (e.g. first run).
+  # from_timestamp =
+  # latest = true
+
+  ## Set a custom prefetch count for the receiver(s)
+  # prefetch_count = 1000
+
+  ## Add an epoch to the receiver(s)
+  # epoch = 0
+
+  ## Change to set a custom user agent, "telegraf" is used by default
+  # user_agent = "telegraf"
+
+  ## To consume from a specific partition, set the partition_ids option.
+  ## An empty array will result in receiving from all partitions.
+  # partition_ids = ["0","1"]
+
+  ## 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
+
+  ## Set either option below to true to use a system property as timestamp.
+  ## You have the choice between EnqueuedTime and IoTHubEnqueuedTime.
+  ## It is recommended to use this setting when the data itself has no timestamp.
+  # enqueued_time_as_ts = true
+  # iot_hub_enqueued_time_as_ts = true
+
+  ## Tags or fields to create from keys present in the application property bag.
+  ## These could for example be set by message enrichments in Azure IoT Hub.
+  # application_property_tags = []
+  # application_property_fields = []
+
+  ## Tag or field name to use for metadata
+  ## By default all metadata is disabled
+  # sequence_number_field = "SequenceNumber"
+  # enqueued_time_field = "EnqueuedTime"
+  # offset_field = "Offset"
+  # partition_id_tag = "PartitionID"
+  # partition_key_tag = "PartitionKey"
+  # iot_hub_device_connection_id_tag = "IoTHubDeviceConnectionID"
+  # iot_hub_auth_generation_id_tag = "IoTHubAuthGenerationID"
+  # iot_hub_connection_auth_method_tag = "IoTHubConnectionAuthMethod"
+  # iot_hub_connection_module_id_tag = "IoTHubConnectionModuleID"
+  # iot_hub_enqueued_time_field = "IoTHubEnqueuedTime"
+
+  ## 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
