psutil (process and system utilities) is a cross-platform library for
retrieving information on running processes and system utilization (CPU,
memory, disks, network) 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 command
line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free,
nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It
currently supports Linux, Windows, OSX, Sun Solaris, FreeBSD, OpenBSD and
NetBSD, both 32-bit and 64-bit architectures, with Python versions from 2.6
to 3.5 (users of Python 2.4 and 2.5 may use 2.1.3 version). PyPy is also
known to work.
- #966: [Linux] sensors_battery().percent is a float and is more precise.
- #964: [Windows] Process.username() and psutil.users() may return badly
decoding character on Python 3.
- #965: [Linux] disk_io_counters() may miscalculate sector size and report
wrong number of bytes read and written.
- #966: [Linux] sensors_battery() may fail with "no such file error".
- #966: [Linux] sensors_battery().power_plugged may lie.
