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 classic UNIX command line tools such as *ps, top, iotop, lsof, netstat, ifconfig, free* and others. psutil currently supports the following platforms: - **Linux** - **Windows** - **macOS** - **FreeBSD, OpenBSD**, **NetBSD** - **Sun Solaris** - **AIX** Supported Python versions are cPython 3.6+ and `PyPy `__. Latest psutil version supporting Python 2.7 is `psutil 6.1.1 `__. Sponsors ======== .. raw:: html
add your logo Funding ======= While psutil is free software and will always be, the project would benefit immensely from some funding. psutil is among the `top 100 `__ most-downloaded Python packages, and keeping up with bug reports, user support, and ongoing maintenance has become increasingly difficult to sustain as a one-person effort. If you're a company that's making significant use of psutil you can consider becoming a sponsor via `GitHub `__, `Open Collective `__ or `PayPal `__. Sponsors can have their logo displayed here and in the psutil `documentation `__. Example usages ============== This represents pretty much the whole psutil API.
