Python psutil module, OS monitoring.

• The psutil module is a cross-platform library for getting information about running processes and system usage (CPU, memory, disks, network, sensors) in Python. This module is useful for system monitoring, profiling, limiting process resources, and managing running processes.

• It implements many features 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 .

Since the psutil module is not part of the Python standard library, it must be installed separately.
