JVM (JMX Exporter)

Tip

This article mainly focuses on collecting JVM-related metrics information via the JMX Exporter method.

Configuration

Description: Enable the jvm collector, which collects jvm Metrics information through the jvm collector.

Application Integration with JMX Exporter

The following examples all use the jar runtime method.

  • Download

Download the version based on actual needs from https://github.com/prometheus/jmx_exporter/releases. Here we choose version 0.18.0.

  • Start configuration javaagent
java -javaagent:jmx_prometheus_javaagent-0.18.0.jar=8080:config.yaml -jar yourJar.jar

DataKit Enable prom Collector

The collector directory is datakit/conf.d/prom. After entering the directory, copy prom.conf.sample and rename the new file to jvm-prom.conf. Mainly configure url, source, and measurement_prefix; other parameters can be adjusted as needed.

urls =["http://localhost:8080/metrics"]
source = "jmx_jmx_exporter_prom"
measurement_prefix = "jvm_"
[inputs.prom.tags]
  server="server"

The above configuration will generate a Measurement set that starts with jvm_.

  • Restart DataKit

Restart DataKit ```
