psutil: Cross-Platform System Information Library
A Python library for retrieving information on running processes and system utilization, allowing easy monitoring of CPU, memory, disk, network, and other system resources.
What is Psutil?
psutil is a cross-platform library for retrieving information on running processes and system utilization in Python. It provides an simple, easy-to-use interface for monitoring different aspects of your system, both software-related and hardware-related.
Some key features of psutil include:
- Retrieving comprehensive information on running processes like name, PID, memory and CPU usage, etc.
- Getting system utilization statistics like CPU, memory, disk and network usage
- Managing running processes by terminating or sending signals to them
- Getting information on disks, network connections, sensors and users currently on the system
- Works on major operating systems like Linux, Windows, macOS, FreeBSD and Sun Solaris
- Lightweight and no dependencies outside Python standard library
psutil makes it very easy to build system monitors, process monitors, system analyzers and profiling tools in Python. If you need to monitor and profile various aspects of a system through Python, psutil is a great choice with an intuitive API.
