The NATS consumer plugin reads from the specified NATS subjects and creates metrics using one of the supported input data formats.
A Queue Group is used when subscribing to subjects so multiple instances of telegraf can read from a NATS cluster in parallel.
[[inputs.nats_consumer]]
## urls of NATS servers
servers = ["nats://localhost:4222"]
## Use Transport Layer Security
secure = false
## subject(s) to consume
subjects = ["telegraf"]
## name a queue group
queue_group = "telegraf_consumers"
## Sets the limits for pending msgs and bytes for each subscription
## These shouldn't need to be adjusted except in very high throughput scenarios
# pending_message_limit = 65536
# pending_bytes_limit = 67108864
## Maximum messages to read from the broker that have not been written by an
## output. For best throughput set based on the number of metrics within
## each message and the size of the output's metric_batch_size.
##
## For example, if each message from the queue contains 10 metrics and the
## output metric_batch_size is 1000, setting this to 100 will ensure that a
## full batch is collected and the write is triggered immediately without
## waiting until the next flush_interval.
# max_undelivered_messages = 1000
## Data format to consume.
## Each data format has its own unique set of configuration options, read
