The JMX exporter is the worst offender here, with the Graphite and StatsD exporters also requiring configuration to extract labels.

We have forked this exporter, enhanced it a bit with a Dockerfile, which adds support for the options we’ve listed.By selecting these links, you may be leaving CVEreport webspace. Running the exporter as a Java Agent is thus strongly encouraged. It can also be run as an independent HTTP server and scrape remote JMX targets, but this comes with various disadvantages, such as it being harder to configure and it being unable to expose process metrics (e.g., memory and CPU usage). It runs as a Java Agent, exposing an HTTP server and serving metrics of the local JVM. For instance, to set up Prometheus for Kafka monitoring, you can use the JMX Exporter to expose metrics as Prometheus-compatible endpoints. They’ve written a collector that can configurably scrape and expose the mBeans of a JMX target. This often involves configuring the monitoring tool to collect metrics from your server, typically via JMX or Kafka's built-in metrics reporters. The folks at Prometheus have a nice solution to all of the above. Also, you’ll have to run a new JVM to collect the available information through JMX and secure the channel somehow. This opens up some options for monitoring, but at the same time raises some questions (for example, about security). The snippet from our deployment descriptor, which installs the Kafka Helm chart with JMX enabled, looks like this: Using existing toolsĪpache Kafka deployments on Kubernetes expose JMX interfaces to interact with. Based on these metrics, we can optimize settings for memory usage, threads, or even by using exposed setters through MBeans. The simplest way to collect information is through JMX, where metrics about the state of the JVM, CPU, Memory, and GC are already available. It’s quite common for Java applications to monitor the JVM itself, since applications do not have a built-in monitoring component.

For further details please read this post. Fetch Metrics Using Prometheus Install JMX Exporter Agent on Kafka broker 1) To fetch the Kafka Metrics from the cluster, we use Java Management Extensions. Note that we have removed Zookeeper from Kafka and we use Etcd instead. This post is about getting into the nitty-gritty of your available options, and exploring some examples of monitoring solutions. Then, configure Prometheus to scrape these endpoints periodically. We have centralized the monitoring of multiple large Kafka clusters with federated Prometheus on Kubernetes. For instance, to set up Prometheus for Kafka monitoring, you can use the JMX Exporter to expose metrics as Prometheus-compatible endpoints. One of the most popular frameworks we deploy to Kubernetes at scale, and one that we love, is Apache Kafka. The clusters, applications or frameworks are all managed by our next generation PaaS, Pipeline.
