psutil

As a comprehensive Python module, psutil delivers powerful system and process monitoring capabilities across multiple operating systems. It allows developers to access detailed information about CPU usage, memory consumption, disk activity, network statistics, and battery status. The library enables process management features like killing processes, checking process existence, and retrieving process environment details. By providing a consistent API regardless of the underlying platform, psutil saves developers from writing platform-specific code and makes system monitoring applications more portable and maintainable.
