## jattacher

A utility to diagnostics JVM processes using the Dynamic Attach mechanism.

It is a Rust implementation of

the [HotSpotVirtualMachine](https://github.com/openjdk/jdk8u/blob/master/jdk/src/share/classes/sun/tools/attach/HotSpotVirtualMachine.java)

and [OpenJ9VirtualMachine](https://github.com/eclipse-openj9/openj9/blob/master/jcl/src/jdk.attach/share/classes/com/ibm/tools/attach/attacher/OpenJ9VirtualMachine.java)

from the tools.jar of the JDK. However, No installed JDK required, works with just JRE.

### Features

- [ ] `jattacher jps` —— List all Java processes along with comprehensive process information, going beyond the default

  JPS output

  provided by OpenJ9 and HotSpot.

- [ ] `jattacher jps --json` —— Output data in JSON format.

- [ ] `jattacher jps --dashboard` —— Display Java process information in real time.
