# Kafka Consumer Input Plugin The [Kafka][kafka] consumer plugin reads from Kafka and creates metrics using one of the supported [input data formats][]. For old kafka version (< 0.8), please use the [kafka_consumer_legacy][] input plugin and use the old zookeeper connection method. ### Configuration ```toml [[inputs.kafka_consumer]] ## kafka servers brokers = ["localhost:9092"] ## topic(s) to consume topics = ["telegraf"] ## Optional Client id # client_id = "Telegraf" ## Set the minimal supported Kafka version. Setting this enables the use of new ## Kafka features and APIs. Of particular interest, lz4 compression ## requires at least version 0.10.0.0. ## ex: version = "1.1.0" # version = "" ## Optional TLS Config # tls_ca = "/etc/telegraf/ca.pem" # tls_cert = "/etc/telegraf/cert.pem" # tls_key = "/etc/telegraf/key.pem" ## Use TLS but skip chain & host verification # insecure_skip_verify = false ## Optional SASL Config # sasl_username = "kafka" # sasl_password = "secret" ## the name of the consumer group consumer_group = "telegraf_metrics_consumers" ## Offset (must be either "oldest" or "newest") offset = "oldest" ## Maximum length of a message to consume, in bytes (default 0/unlimited); ## larger messages are dropped max_message_len = 1000000 ## 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 ## more about them here: ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md data_format = "influx" ``` [kafka]: https://kafka.apache.org [kafka_consumer_legacy]: /plugins/inputs/kafka_consumer_legacy/README.md [input data formats]: /docs/DATA_FORMATS_INPUT.md
