# jvm-mon

Console based JVM monitoring - when you just want to SSH into a server and see what's going on.

jvm-top lets you monitor your JVM server applications from the terminal.

# New Version

Release: [1.3](https://github.com/ajermakovics/jvm-mon/releases/tag/1.3)

- Rewritten in Go 

- Single executable file

- Can monitor applications on Java 8 and above

- Does not require an existing JDK

How it works:

 - jvm-mon executable comes bundled with a Java agent jar

 - On startup it extracts the agent to a temp directory

 - It attaches to the JVM you want to monitor

 - Loads agent into running JVM to collect metrics

 - Agent and app establish a socket connection to send metrics

# Install

Download from [latest release](https://github.com/ajermakovics/jvm-mon/releases)

### macOS

```

brew install jvm-mon

```

# Usage

- Select a JVM process and press Enter to monitor it

- Press q or Ctrl+C to exit

- Press Del or Backspace to kill a process

# What is available

Currently it shows:

- List of running JVM processes

- Cpu and GC load

- Heap size and usage

- Top threads with cpu usage

# Building from source
