jvm-mon

JVM monitoring from the terminal (cpu, memory, threads). Supports monitoring application running on Java 8 and newer.

• Single Go executable
• Contains embedded Java agent that gets loaded into monitored application
• Does not require a JDK to run

Usage

Build from source

Prerequisites:

• Go (at least 1.18)
• JDK 8+ for building java agent

1. Build everything: ./build.sh
2. ./run.sh:

How it works

jvm-mon attaches to a running JVM you select and loads an agent.jar into the process. They communicate via a socket to send/receive JVM metrics in json format.

Development

Run jvm-mon from Go sources: ./run.sh
