              ## 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

              ## Maximum amount of time the consumer should take to process messages. If
              ## the debug log prints messages from sarama about 'abandoning subscription
              ## to [topic] because consuming was taking too long', increase this value to
              ## longer than the time taken by the output plugin(s).

              ## The default number of message bytes to fetch from the broker in each
              ## request (default 1MB). This should be larger than the majority of
              ## your messages, or else the consumer will spend a lot of time
              ## negotiating sizes and not actually consuming. Similar to the JVM's
              ## `fetch.message.max.bytes`.
              # consumer_fetch_default = "1MB"

              ## Data format to consume.
              ## Each data format has its own unique set of configuration options, read
