psutil

psutil streamlines system monitoring by providing a unified Python API that works seamlessly across Windows, Linux, macOS, and BSD systems. The library eliminates the complexity of parsing command-line output by offering direct access to system metrics including CPU times, memory statistics, disk I/O, network interfaces, and running processes. Developers can easily track resource consumption, identify performance bottlenecks, and manage system processes through intuitive Python functions. This makes psutil particularly valuable for creating system administration tools, resource monitors, and performance tracking applications.
