Introduction

Kafka metrics can be collected and displayed using different methods.

Prometheus

Prometheus can be used to collect monitoring data from Kafka.

...

    scrape_configs:
    - job_name: prometheus
      static_configs:
      - targets:
        - localhost:9090
    - job_name: kafka-exporter
      scrape_interval: 10s
      metrics_path: /metrics
      static_configs:
      - targets:
        - kafka-exporter.kafka:9100

Grafana

You can then setup the grafana dashboard to view your metrics : kafka-exporter-overview_rev5.json

...

You can also include metrics from your Kafka bridge by adding the following line to the bridge spec: enableMetrics: true

Note: It is also possible to obtain JMX metrics using jolokia (GitHub - paksu/kafka-jolokia-telegraf-collector: Simple Kafka broker JMX metric collection with Telegraf) but this requires creating a custom a custom kafka cluster image if you are using Strimzi.

InfluxDB

To store these metrics in InfluxDB you need to do is setup up a bucket and a metrics scraper for the kafka-exporter metrics endpoint.

You can then view the metrics in data explorer.
