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 <https://pypy.org/>`__.
Latest psutil version supporting Python 2.7 is
`psutil 6.1.1 <https://pypi.org/project/psutil/6.1.1/>`__.

Example usages
==============

This represents pretty much the whole psutil API.

Further process APIs
--------------------

.. code-block:: python

    >>> import psutil
    >>> for proc in psutil.process_iter(['pid', 'name']):
    ...     print(proc.info)
    ...
    {'pid': 1, 'name': 'systemd'}
    {'pid': 2, 'name': 'kthreadd'}
    {'pid': 3, 'name': 'ksoftirqd/0'}
    ...
    >>>
    >>> psutil.pid_exists(3)
    True
    >>>
    >>> def on_terminate(proc):
    ...     print("process {} terminated".format(proc))
    ...
    >>> # waits for multiple processes to terminate
    >>> gone, alive = psutil.wait_procs(procs_list, timeout=3, callback=on_terminate)
    >>>

Heap info
---------

.. code-block:: python

    >>> import psutil
    >>> psutil.heap_info()
    pheap(heap_used=5177792, mmap_used=819200)
    >>> psutil.heap_trim()
