Top 7 Java java-agent Projects

Byte Buddy

5 6,006 9.0 Java

Runtime code generation for the Java virtual machine.

Project mention: Monkey-patching in Java | dev.to | 2023-09-21

As seen above, the API exposes the user to low-level bytecode manipulation via byte arrays. It would be unwieldy to do it directly. Hence, real-life projects rely on bytecode manipulation libraries. ASM has been the traditional library for this, but it seems that Byte Buddy has superseded it. Note that Byte Buddy uses ASM but provides a higher-level abstraction.

JaCoCo

7 4,014 8.3 Java

:microscope: Java Code Coverage Library

Project mention: Apache Maven JaCoCo Configuration | dev.to | 2023-10-27

I will use here JaCoCo, where also the JaCoCo-Maven-lugin exists for the usage in your Maven builds. This article will show how to configure the code coverage to finally get the results for unit- and integration-tests.

Project mention: Prometheus JMX Exporter for Java17 | /r/PrometheusMonitoring | 2023-05-09

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:
