Prometheus JMX Exporter for Java17

This page summarizes the projects mentioned and recommended in the original post on /r/PrometheusMonitoring

  • InfluxDB - Collect and Analyze Billions of Data Points in Real Time
  • Mergify - Updating dependencies is time-consuming.

  • jmx_exporter

    A process for exposing JMX Beans via HTTP for Prometheus consumption

    not quite sure if this is where I should be asking for help but i'm kind of befuddled about this whole situation. I'm trying to set up https://github.com/prometheus/jmx_exporter for our containerized Java application on our cluster. Specifically the JavaAgent as we are interested in getting the CPU and memory metrics especially. However, getting it initialized I am faced with this:

  • client_java

    Prometheus instrumentation library for JVM applications

    After doing some research it appears this class references internal packages and therefore "makes it unusable for modern Java apps" (https://github.com/prometheus/client_java/issues/533 , https://github.com/open-telemetry/opentelemetry-java/issues/4192)

  • InfluxDB

    Collect and Analyze Billions of Data Points in Real Time. Manage all types of time series data in a single, purpose-built database. Run at any scale in any environment in the cloud, on-premises, or at the edge.

  • opentelemetry-java

    OpenTelemetry Java SDK

  • cadvisor

    Analyzes resource usage and performance characteristics of running containers.

    For CPU and memory metrics, you can use cAdvisor to collect container level data.

  • In case you don’t get it working you could try JMX metrics from OTEL contrib. Configure it for the Prom exporter.

  • example.java.helloworld

    "Hello World" Example for Java

    Download this package to your container: https://github.com/macagua/example.java.helloworld Compile Main.java and create the jar file according to the instructions. Run the jar file with the jmx exporter with:
