The [NATS](http://www.nats.io/about/) consumer plugin reads from
|
2016-02-10 23:28:52 +00:00
|
|
|
specified NATS subjects 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).

|
|
|
A [Queue Group](http://www.nats.io/documentation/concepts/nats-queueing/)
|
|
|
|
|
is used when subscribing to subjects so multiple instances of telegraf can read
|
|
|
|
|
from a NATS cluster in parallel.
