This is ## useful when telegraf needs to restart it don't miss a ## message.

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 ## 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"
