xnos

xnos is a C++17 hardware monitor with a platform-neutral core and native OS backends.

It currently reports CPU, memory, GPU basics, and battery where supported. Missing values are represented as N/A in terminal output and null in JSON output.

Features

• Cross-platform monitor interface with Linux, Windows, and macOS backends
• Dashboard, compact, detailed, and JSON terminal modes
• INI-style configuration support
• Threshold alerts for CPU and memory
• Optional JSON-lines logging
• CMake build, unit tests, and GitHub Actions CI

Build

cmake -B build -DBUILD_TESTS=ON
cmake --build build --parallel
ctest --test-dir build --output-on-failure

On Windows with a multi-config generator, add --config Release or --config Debug to the build and test commands.

Run

./build/iso-kernos --mode dashboard
./build/iso-kernos --compact
./build/iso-kernos --json --duration 5
./build/iso-kernos --test-mode --mode compact
