Summary
psutil (process and system utilities) is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, network, sensors) in Python. It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. It implements many functionalities offered by UNIX command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. psutil currently supports the following platforms:
- Linux
- Windows
- macOS
- FreeBSD, OpenBSD, NetBSD
- Sun Solaris
- AIX
…both 32-bit and 64-bit architectures. Supported Python versions are 2.6, 2.7 and 3.4+. PyPy is also known to work.
Projects using psutil
psutil has roughly the following monthly downloads:
There are over 10.000 open source projects on github which depend from psutil. Here’s some I find particularly interesting:
Portings
Example usages
This represents pretty much the whole psutil API.
