Basically, the conifguration is used to transform the metrics in the way prometheus understands. The description of yml file can be found here. This exporter is intended to be run as a Java Agent, exposing a HTTP server and serving metrics of the local JVM.ĭownload the JMX Prometheus Java agent by the following command: sudo wget -P /opt/kafka/prometheus/ ĭownload the config for java agent: cd /opt/kafka/prometheus/ The collected data in Promethues can be later shown in Grafana. JMX Prometheus exporter is a collector that can bed configured to scrape and expose mBeans of a JMX target. The result can have a significant impact on the overall behavior of the application.

This means that we can change a program by adding code to it without having to touch upon the actual source code of the program. This can be done both statically and dynamically. The Instrumentation APIs provide a mechanism to modify bytecodes of methods. Java agents are part of the Java Instrumentation API. If your kafka broker is not set up, please follow the step by step guide here. There are other exporters too like Nagios XI check_jmx plugin, jmxtrans, Jolokia and MX4J. In this tutorial, we are going to use JMX Prometheus exporter. We can get access through JConsole or through the communication adaptor or connectors available.
We need to now access the data by exposing it in some manner. Kafka created the MBean and registered it. It provides Java developers with the means to instrument Java code, create smart Java agents, implement distributed management middleware and managers, and easily integrate these solutions into existing management and monitoring systems.Īpplication, in our case, Kafka has to implement an interface called MBean of Java. JMX provides API to monitor and manage your resources at runtime. One way to use them in an external monitoring system is to use a collection agent provided by Prometheus and attach it to the Kafka process. All of the metrics exposed by Kafka can be accessed via the Java Management Extensions (JMX) interface. We are going to collect these measurements in Prometheus and later make a dashboard in Grafana.
There are a number of measurement collected while Kafka is operational. Reliable Data Delivery in Kafka How do your monitor your Kafka setup?
