Kafka Monitoring Template with Telegraf and Jolokia

Dashboards

Kafka

Kafka Producer Metrics

Kafka Consumer Metrics

Kafka JVM

Quick Install

InfluxDB UI

In the InfluxDB UI, go to Settings->Templates and enter this URL: https://raw.githubusercontent.com/influxdata/community-templates/master/kafka/kafka-template.yml

Influx CLI

If you have your InfluxDB credentials configured in the CLI, you can install this template with:

influx apply -f https://raw.githubusercontent.com/influxdata/community-templates/master/kafka/kafka-template.yml

Requirements

  • Set environment variables on host/s from which Telegraf will be sending metrics. These are:
    • INFLUX_ORG
    • INFLUX_TOKEN
    • INFLUX_HOST
    • INFLUX_BUCKET
    • KAFKA_JOLOKIA_HOSTS
    • KAFKA_PRODUCERS_JOLOKIA_HOSTS
    • KAFKA_CONSUMERS_JOLOKIA_HOSTS
    • ZOOKEEPER_HOST
  • Jolokia JVM Agent
  • Apache Kafka
  • Apache Zookeeper

Note: Kafka and Zookeper can be easily obtained and managed through the open source Confluent Platform.

Setup Instructions

Once installed, you'll need to start up Telegraf to pull metrics from your Jolokia-attached Kafka broker/s. Checkout Telegraf docs for installing and starting Telegraf.

To start Telegraf with the template-provided configuration, you can do one of two things:

  • Call the configuration at its new address:

    • Locate your configuration and open its setup instructions:
    • Copy Telegraf startup command provided for you (with your configuration's unique address):
    • Run that command and you're writing your Kafka data to your InfluxDB instance.

  • Run with local copy of configuration

    • Locate the configuration the same as above
    • Click the name of the configuration to open it up
    • Click the Download button at the bottom
    • Deploy and run Telegraf as you would any other way, now with that file

Included resources

  • 2 label: kafka, jvm
  • 1 Telegraf Configuration: kafka-zk-jolokia
  • 4 Dashboards: Kafka Metrics, Kafka Consumer Metrics, Kafka Producer Metrics and Kafka JVM Metrics
  • 7 Variables: bucket, kafka_broker, kafka_topic, kafka_consumer, kafka_consumer_partition, kafka_producer and jvm_host

Pre-work

  • This template does not require -- and therefore support -- TLS configurations. If you have TLS enabled for Jolokia/Zookeeper, you will want to provide that information to the Telegraf configuration. Simply follow this for Jolokia and this for Zookeeper. Comprehensive TLS docs as it pertains to Telegraf can be found here.

Telegraf inputs
