Summary

Glances is a cross-platform monitoring tool which aims to present a large amount of monitoring information through a curses or Web based interface. The information dynamically adapts depending on the size of the user interface.

.. image:: https://raw.githubusercontent.com/nicolargo/glances/develop/docs/\_static/glances-summary.png

It can also work in client/server mode. Remote monitoring could be done via terminal, Web interface or API (XML-RPC and RESTful). Stats can also be exported to files or external time/value databases.

Glances is written in Python and uses libraries to grab information from your system. It is based on an open architecture where developers can add new plugins or exports modules.

Note for Python 2.6 users

Glances no longer supports Python 2.6. Please upgrade to a minimum Python version of 2.7/3.4+ or downgrade to Glances 2.6.2 (last version with Python 2.6 support).

Note for CentOS Linux 6 and 7 users

Python 2.7 and 3.4 are now available via SCL repositories. See: https://lists.centos.org/pipermail/centos-announce/2015-December/021555.html.

Installation

There are several methods to test/install Glances on your system. Choose your weapon!

Glances Auto Install script: the total way

To install both dependencies and the latest Glances production ready version (aka master branch), just enter the following command line:

.. code-block:: console

curl -L https://bit.ly/glances | /bin/bash

or

.. code-block:: console

wget -O- https://bit.ly/glances | /bin/bash

Note: This is only supported on some GNU/Linux distributions and Mac OS X. If you want to support other distributions, please contribute to

glancesautoinstall

_.

PyPI: The simple way

Glances is on

PyPI

. By using PyPI, you will be using the latest stable version.

To install, simply use

pip

:

.. code-block:: console

pip install glances

Note: Python headers are required to install

psutil

_. For example, on Debian/Ubuntu you need to install first the python-dev package. For Fedora/CentOS/RHEL install first python-devel package. For Windows, just install psutil from the binary installation file.

Note 2 (for the Wifi plugin): If you want to use the Wifi plugin, you need to install the wireless-tools package on your system.

You can also install the following libraries in order to use optional features (like the Web interface, exports modules...):

.. code-block:: console

pip install 'glances[action,browser,cloud,cpuinfo,docker,export,folders,gpu,graph,ip,raid,snmp,web,wifi]'

To upgrade Glances to the latest version:

.. code-block:: console

pip install --upgrade glances pip install --upgrade glances[...]

If you need to install Glances in a specific user location, use:

.. code-block:: console

export PYTHONUSERBASE=~/mylocalpath pip install --user glances

Docker: the funny way

A Glances container is available. It includes the latest development HEAD version. You can use it to monitor your server and all your other containers!

Get the Glances container:

.. code-block:: console

docker pull nicolargo/glances

Run the container in console mode:

.. code-block:: console

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock:ro --pid host --network host -it docker.io/nicolargo/glances

Additionally, if you want to use your own glances.conf file, you can create your own Dockerfile:

.. code-block:: console

FROM nicolargo/glances COPY glances.conf /glances/conf/glances.conf CMD python -m glances -C /glances/conf/glances.conf $GLANCES\_OPT

Alternatively, you can specify something along the same lines with docker run options:

.. code-block:: console

docker run -v `pwd`/glances.conf:/glances/conf/glances.conf -v /var/run/docker.sock:/var/run/docker.sock:ro --pid host -it docker.io/nicolargo/glances

Where pwd/glances.conf is a local directory containing your glances.conf file.

Run the container in Web server mode (notice the

GLANCES\_OPT

environment variable setting parameters for the glances startup command):

.. code-block:: console

docker run -d --restart="always" -p 61208-61209:61208-61209 -e GLANCES\_OPT="-w" -v /var/run/docker.sock:/var/run/docker.sock:ro --pid host docker.io/nicolargo/glances

GNU/Linux

Glances

is available on many Linux distributions, so you should be able to install it using your favorite package manager. Be aware that when you use this method the operating system

package

_ for

Glances

may not be the latest version.

FreeBSD

To install the binary package:

.. code-block:: console

# pkg install py27-glances

To install Glances from ports:

.. code-block:: console

# cd /usr/ports/sysutils/py-glances/ # make install clean

macOS

If you do not want to use the glancesautoinstall script, follow this procedure.

macOS users can install Glances using

Homebrew

or

MacPorts

.

Homebrew ````````

.. code-block:: console

$ brew install glances

MacPorts ````````

.. code-block:: console

$ sudo port install glances

Windows

Install

Python

_ for Windows (Python 2.7.9+ and 3.4+ ship with pip) and then run the following command:

.. code-block:: console

$ pip install glances

Alternatively, you could clone the repository and install with the following command.

.. code-block:: console

$ git clone https://github.com/nicolargo/glances.git $ cd glances $ python setup.py install

Android

You need a rooted device and the

Termux

_ application (available on the Google Play Store).

Start Termux on your device and enter:

.. code-block:: console

$ apt update $ apt upgrade $ apt install clang python $ pip install bottle $ pip install glances

And start Glances:

.. code-block:: console

$ glances

You can also run Glances in server mode (-s or -w) in order to remotely monitor your Android device.

Source

To install Glances from source:

.. code-block:: console

$ wget https://github.com/nicolargo/glances/archive/vX.Y.tar.gz -O - | tar xz $ cd glances-\* # python setup.py install

Note: Python headers are required to install psutil.

Chef

An awesome

Chef

cookbook is available to monitor your infrastructure: https://supermarket.chef.io/cookbooks/glances (thanks to Antoine Rouyer)

Puppet

You can install Glances using

Puppet

: https://github.com/rverchere/puppet-glances

Ansible

A Glances

Ansible

role is available: https://galaxy.ansible.com/zaxos/glances-ansible-role/

Usage

For the standalone mode, just run:

.. code-block:: console

$ glances

For the Web server mode, run:

.. code-block:: console

$ glances -w

and enter the URL

http://<ip>:61208</ip>

in your favorite web browser.

For the client/server mode, run:

.. code-block:: console

$ glances -s

on the server side and run:

.. code-block:: console

$ glances -c <ip>
</ip>

on the client one.

You can also detect and display all Glances servers available on your network or defined in the configuration file:

.. code-block:: console

$ glances --browser

You can also display raw stats on stdout:

.. code-block:: console

$ glances --stdout cpu.user,mem.used,load cpu.user: 30.7 mem.used: 3278204928 load: {'cpucore': 4, 'min1': 0.21, 'min5': 0.4, 'min15': 0.27} cpu.user: 3.4 mem.used: 3275251712 load: {'cpucore': 4, 'min1': 0.19, 'min5': 0.39, 'min15': 0.27} ...

or in a CSV format thanks to the stdout-csv option:

.. code-block:: console

$ glances --stdout-csv now,cpu.user,mem.used,load now,cpu.user,mem.used,load.cpucore,load.min1,load.min5,load.min15 2018-12-08 22:04:20 CEST,7.3,5948149760,4,1.04,0.99,1.04 2018-12-08 22:04:23 CEST,5.4,5949136896,4,1.04,0.99,1.04 ...

and RTFM, always.
