We are currently trying to get the Kafka Connect metrics into Prometheus via the JMX exporter. JMX Exporter Prometheus provide JMX Exporter, a collector that can configurably scrape and expose mBeans of a JMX target. With v 1.0.0, Kafka Connect has dramatically improved its monitoring capabilities. Need help monitoring Kafka, Java apps, or other Dockerized applications? Contact us. We therefore need a way of exposing the Kafka Connect metrics over HTTP in the format that Prometheus understands. The ports and host name of each component may be configured inside of docker-compose.yml for a non localhost setup. Kafka Exporter is provided with AMQ Streams for deployment with a Kafka cluster to extract additional metrics data from Kafka brokers related to offsets, consumer groups, consumer lag, and topics. ![]() It's currently set to simply scrape the running JMX exporter agent. Kafka Exporter is an open source project to enhance monitoring of Apache Kafka brokers and clients. If you wish to edit the Prometheus configuration file, you can find it under mount/prometheus/prometheus.yml. You should now be able to head over to Prometheus and query some Kafka, JMX, and JVM metrics. This blogpost assumes that you already have Docker and Docker Compose installed on your machine.īegin by grabbing the example code which contains a Docker setup that will spin up Zookeeper (a Kafka dependency), a Kafka instance, the JMX exporter agent, and a Prometheus instance to monitor it all.ĭo this by running docker-compose up inside of the prometheus_kafka/ directory. This time however, Kafka and the JMX exporter Java agent will be inside of a Docker container. Like the last post on this topic, we'll be using the JMX exporter to expose Kafka's metrics for our Prometheus to scrape. We also add a Prometheus exporter JAR that scrapes the Kafka Connect JMX metrics. ![]() Previously we've looked at monitoring Kafka using Prometheus. In our case, we add sink connectors for AWS Kinesis and Google Cloud PubSub. While Prometheus has a JMX exporter that is configured to scrape and expose mBeans of a JMX target, Kafka Exporter is an used to enhance monitoring of Apache Kafka brokers and clients by extracting additional metrics data from Kafka brokers related to offsets, consumer groups, consumer lag, and topics.
