OSHI is a free, cross-platform Java library for retrieving native operating system and hardware information using JNA or the JDK Foreign Function & Memory API, with no additional native library installation required. It exposes a unified API for OS version, processes, CPU and memory usage, disks, filesystems, network interfaces, sensors, batteries, USB devices, GPUs, and more across Windows, macOS, Linux, and UNIX platforms.

Use cases

• get cpu and memory usage in java
• list running processes with cpu and memory stats
• read disk and partition information cross-platform
• monitor system temperature and fan speeds
• detect operating system version and hardware details
• query network interface bandwidth and stats
• build a java system monitoring dashboard
• get battery and usb device info from java

When to choose

• you need cross-platform system/hardware metrics from Java without native dependencies
• you want a single unified API covering Windows, macOS, Linux, and BSD/UNIX
• you need detailed process, filesystem, network, or sensor data for monitoring tools

When to avoid

• you are not working on the JVM (use psutil, sigar, or OS-native tools instead)
• you only need metrics for one OS and prefer a lighter native-specific solution
• you need real-time low-overhead telemetry rather than on-demand polling
