glances - A cross-platform curses-based system monitoring tool


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
show this help message and exit

-V, --version
show program's version number and exit

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

path to the configuration file

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

disable bold mode in the terminal

disable disk I/O module

disable file system module

disable network module

disable sensors module

disable network, disk IO, FS and sensors modules

disable process module

disable log module

enable extended stats on top process

enable the history mode

B --path-history PATH_HISTORY
set the export path for graph history

--export-csv CSV_FILE
export stats to a CSV file

export stats to an InfluxDB server

export stats to a Statsd server

-s, --server
run Glances in server mode

start the client browser (display list of servers)

disable autodiscover feature

-c CLIENT, --client CLIENT
connect to a Glances server by IPv4/IPv6 address or hostname

-p PORT, --port PORT
define the client/server TCP port [default: 61209]

define a client/server password from the prompt or file

bind server to the given IPv4/IPv6 address or hostname

--snmp-community SNMP_COMMUNITY
SNMP community

--snmp-port SNMP_PORT
SNMP port

--snmp-version SNMP_VERSION
SNMP version (1, 2c or 3)

--snmp-user SNMP_USER
SNMP username (only for SNMPv3)

--snmp-auth SNMP_AUTH
SNMP authentication key (only for SNMPv3)

Force the SNMP mode (do not try Glances server)

-t TIME, --time TIME
set refresh time in seconds [default: 3 sec]

-w, --webserver
run Glances in Web server mode

-1, --percpu
start Glances in per CPU mode

-1, --process-short-name
Force short name for processes name

-1, --fs-free-space
Display FS free space instead of used

-1, --theme-white
Optimize display for white background


You can use the following keys while in Glances:

ENTER Set the process filter pattern (as a regular expression)

a Sort process list automatically

b Switch between bit/s or Byte/s for network I/O

c Sort processes by CPU usage

d Show/hide disk I/O stats

e Enable/disable top extended stats

f Show/hide file system stats g Generate graphs for current history

h Show/hide the help screen

i Sort processes by I/O rate

l Show/hide log messages

m Sort processes by MEM usage

n Show/hide network stats

p Sort processes by name

q Quit

r Reset history

s Show/hide sensors stats

T Sort process by CPU times (TIME+)

t View network I/O as combination

u View cumulative network I/O

w Delete finished warning log messages

x Delete finished warning and critical log messages

z Show/hide processes stats

z Show/hide processes list (for low CPU consumption)

1 Switch between global CPU and per-CPU stats


Refresh information every 5 seconds:
glances -t 5


Glances returns a zero exit status if it succeeds to print/grab information.

It returns 2 if it fails to parse its options (missing arguments, invalid value, etc).
