glances [OPTIONS]

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 additionnal information. It can adapt dynamically the displayed information depending on the terminal size.

Glances can also work in client/server mode. Remote monitoring could be done via terminal or web interface.

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.

The command-line options are the following:

-h, --help

display the help and exit

-V, --version

show program's version number and exit

-d, --debug

Enable debug mode (log file is /tmp/glances.log)

-b, --byte

display network rate in byte per second [default: bit per second]

-C CONF_FILE, --config CONF_FILE

path to the configuration file

--enable-history

enable the history mode

--disable-bold

disable bold mode in the terminal
