Thanks Fix the Debian package build #752, #650. Fix jmx_exporter_build_info metric #768. jmx_prometheus_httpserver-0.18.0_java6.jar is compatible with Java 6.įixes and enhancements included in this release:.jmx_prometheus_httpserver-0.18.0.jar requires Java >= 7.jmx_prometheus_javaagent-0.18.0_java6.jar is compatible with Java 6.jmx_prometheus_javaagent-0.18.0.jar requires Java >= 7.However, if you have automated security scanners complaining about the vulnerable snakeyaml version this update will help.Īs always, the jmx_exporter binaries are available on Maven central: That means unless you have untrusted 3rd parties write your jmx_exporter config the CVE does not apply. Note that jmx_exporter uses snakeyaml only to parse its config file. Kafka_server_kafkaserver_yammer_metrics_count as the metric.This release updates the snakeyaml dependency from 1.32 to 2.0, because version 1.32 is vulnerable to CVE-2022-1471. You should be able to see following screen on prometheus for any kafka metrics of your choice. Run the prometheus using following command./prometheus -config.file=prometheus.yml # A scrape configuration containing exactly one endpoint to scrape: # Load rules once and periodically evaluate them according to the global 'evaluation_interval'. # scrape_timeout is set to the global default (10s). Default is every 1 minute.Įvaluation_interval: 5s # Evaluate rules every 15 seconds. Scrape_interval: 5s # Set the scrape interval to every 15 seconds. Add localhost:7071 as the scrape target as shown below. Kafka Broker Metrics Scrape Metrics data in Prometheusįollow the instruction here to download Prometheus. Start your kafka bin/kafka-server-start.sh config/server.properties Metrics exposed over http KAFKA_HEAP_OPTS is an environment variable that you can set to pass custom heap settings to the Java Virtual Machine (JVM) that runs Kafka export KAFA_HEAP_OPTS="-Xmx1000M -Xms1000M" Kafka_OPTS is an environment variable that you can set to pass custom settings to the Java Virtual Machine (JVM) that runs Kafka export KAFKA_OPTS="-javaagent:/opt/kafka/prometheus/jmx_prometheus_javaagent-0.12.0.jar=7071:/opt/kafka/prometheus/kafka-2_0_0.yml" Setting Heap Options 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? If you are new to Kafka, please read the first three posts of the series given below.
