.SH NAME
glances \- A cross-platform curses-based system monitoring tool
.SH SYNOPSIS
.B glances
.RI [ OPTIONS ]
.SH DESCRIPTION
Glances is a free (LGPL) cross-platform curses-based system 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 additional information. It can adapt
dynamically the displayed information depending on the terminal size.
.PP
Glances can also work in client/server mode. Remote monitoring could be done via
terminal or web interface.
.PP
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 and so on.
