SYNOPSIS

glances [-bdehmnrsvyz1] [-B bind] [-c server] [-C conffile] [-f file] [-o output] [-p port] [-P password] [-t refresh]

DESCRIPTION

Glances is a free (LGPL) cross-platform curses-based monitoring tool which aims to present a maximum of information in a minimum of space, ideally to fit in a classical 80x24 terminal or higher to have additionnal information.

Glances can adapt dynamically the displayed information depending on the terminal size. It can also work in a client/server mode for remote monitoring.

This tool is written in Python and uses the psutil library to fetch the statistical values from key elements, like CPU, load average, memory, network, disks, file systems, processes, etc.
