Kafka Output Plugin
This plugin writes to a Kafka Broker acting a Kafka Producer.
Configuration:
[[outputs.kafka]]
## URLs of kafka brokers
brokers = ["localhost:9092"]
## Kafka topic for producer messages
topic = "telegraf"
## Optional topic suffix configuration.
## If the section is omitted, no suffix is used.
## Following topic suffix methods are supported:
## measurement - suffix equals to separator + measurement's name
## tags - suffix equals to separator + specified tags' values
## interleaved with separator
## Suffix equals to "_" + measurement's name
# [outputs.kafka.topic_suffix]
# method = "measurement"
# separator = "_"
## Suffix equals to "__" + measurement's "foo" tag value.
## If there's no such a tag, suffix equals to an empty string
# [outputs.kafka.topic_suffix]
# method = "tags"
# keys = ["foo"]
# separator = "__"
## Suffix equals to "_" + measurement's "foo" and "bar"
## tag values, separated by "_". If there is no such tags,
## their values treated as empty strings.
# [outputs.kafka.topic_suffix]
# method = "tags"
# keys = ["foo", "bar"]
# separator = "_"
## Telegraf tag to use as a routing key
## ie, if this tag exists, its value will be used as the routing key
routing_tag = "host"
## CompressionCodec represents the various compression codecs recognized by
## Kafka in messages.
## 0 : No compression
## 1 : Gzip compression
## 2 : Snappy compression
# compression_codec = 0
## RequiredAcks is used in Produce Requests to tell the broker how many
## replica acknowledgements it must see before responding
## 0 : the producer never waits for an acknowledgement from the broker.
## This option provides the lowest latency but the weakest durability
## guarantees (some data will be lost when a server fails).
## 1 : the producer gets an acknowledgement after the leader replica has
## received the data. This option provides better durability as the
## client waits until the server acknowledges the request as successful
## (only messages that were written to the now-dead leader but not yet
## replicated will be lost).
## -1: the producer gets an acknowledgement after all in-sync replicas have
## received the data. This option provides the best durability, we
## guarantee that no messages will be lost as long as at least one in
## sync replica remains.
# required_acks = -1
## The maximum number of times to retry sending a metric before failing
## until the next flush.
# max_retry = 3
## Optional SSL Config
# ssl_ca = "/etc/telegraf/ca.pem"
# ssl_cert = "/etc/telegraf/cert.pem"
# ssl_key = "/etc/telegraf/key.pem"
## Use SSL but skip chain & host verification
# insecure_skip_verify = false
## Optional SASL Config
# sasl_username = "kafka"
# sasl_password = "secret"
## Data format to output.
## 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_OUTPUT.md
# data_format = "influx"
max_retry
This option controls the retries before notification of failure is displayed
per message when no acknowledgement is received from the broker. When this
option is greater than 0
it can reduce message latency and duplicate
messages in the case of transient errors, but may also increase the load on
the broker during periods of downtime.
The option is similar to the retries Producer option in the Java Kafka Producer.
