# Intro
A simple tool to respot java processes resources usage, including:
* Heap usage
* RAM usage
* CPU usage
* GC usage
Inspired by [jps_stat](https://github.com/amarjeetanandsingh/jps_stat).
Requirements:
* This tool only supports Ubuntu at the moment (if you wish to add support to your OS please submit a PR).
* jps and jstat (both are bundled with the JDK).
# Usage
Download the [latest](https://github.com/narkisr/jps-stat/releases/latest) release and add it to you path.
```bash
$ jps-stats top
pid name heap gc ram cpu
-------------------------------------
20699 main 311MB 0.0% 293MB 0.2%
21084 main 131MB 0.0% 964MB 1.8%
# Show raw data (no filtering)
$ jps-stats raw
{:pid 22873, :name Jps, :heap nil, :gc nil, :ram nil, :cpu nil}
{:pid 20699, :name main, :heap 311.74189453125, :gc 0.000M, :ram 293.8486328125, :cpu 0.2M}
{:pid 21084, :name main, :heap 149.922265625, :gc 0.000M, :ram 964.1796875, :cpu 1.8M}
# Filter pid's with partial data same as top
$ jps_stat raw --f true
{:pid 20699, :name main, :heap 311.74189453125, :gc 0.000M, :ram 293.8486328125, :cpu 0.2M}
{:pid 21084, :name main, :heap 149.922265625, :gc 0.000M, :ram 964.1796875, :cpu 1.8M}
```
# Build
Make sure to have the latest graalvm native-image tool:
```bash
$ lein uberjar
$ native-image -jar target/jps-stat-0.2.2-standalone.jar --no-fallback --report-unsupported-elements-at-runtime --initialize-at-build-time --allow-incomplete-classpath
```
