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.

macOS users can install Glances using ``Homebrew`` or ``MacPorts``.
Homebrew
````````
.. code-block:: console
$ brew install glances

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`` 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>
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
