oshi-demo

OSHI Demo Module

Proof-of-concept examples demonstrating OSHI capabilities, including a Swing GUI, JSON output, JMX integration, and utility tools.

Quick Start with jbang

The fastest way to try OSHI — no clone or build required:

# List all available demos
jbang alias list oshi/oshi

# JSON dump of all system info
jbang json@oshi/oshi

# Swing GUI dashboard
jbang gui@oshi/oshi

# Detect if running in a VM
jbang detectvm@oshi/oshi

# Generate a unique machine identifier
jbang id@oshi/oshi

# Show disk store for a given path
jbang diskstore@oshi/oshi

Running from Source

# Build the project
./mvnw install -DskipTests

# Run any demo class
./mvnw exec:java -pl oshi-demo -Dexec.mainClass="oshi.demo.Json"
./mvnw exec:java -pl oshi-demo -Dexec.mainClass="oshi.demo.OshiGui"

Available Demos

Class	Description
Json	Dumps all system information as JSON
OshiGui	Swing GUI with CPU, memory, disk, network panels
DetectVM	Detects virtual machine environments
ComputerID	Generates a unique hardware-based machine identifier
DiskStoreForPath	Shows which disk store backs a given file path
OshiHTTPServer	Simple HTTP server exposing system info
PollGpuStats	Polls and displays GPU statistics
SmcDump	Dumps macOS SMC sensor keys

JMX Integration

The oshi.demo.jmx package demonstrates exposing OSHI data via JMX MBeans:

./mvnw exec:java -pl oshi-demo -Dexec.mainClass="oshi.demo.jmx.demo.OshiJMXServer"

Then connect with jconsole or any JMX client to browse system metrics as MBeans.
