Summary

Glances is an open-source system cross-platform monitoring tool. It allows real-time monitoring of various aspects of your system such as CPU, memory, disk, network usage etc. It also allows monitoring of running processes, logged in users, temperatures, voltages, fan speeds etc. It also supports container monitoring, it supports different container management systems such as Docker, LXC. The information is presented in an easy to read dashboard and can also be used for remote monitoring of systems via a web interface or command line interface. It is easy to install and use and can be customized to show only the information that you are interested in.

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, CSV or direct output to STDOUT.

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.

Installation

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

PyPI: Pip, the standard way

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

To install Glances, simply use the pip command line.

Warning: on modern Linux operating systems, you may have an externally-managed-environment error message when you try to use pip. In this case, go to the the PipX section below.

.. code-block:: console

pip install --user glances

Note: Python headers are required to install psutil_, a Glances dependency. For example, on Debian/Ubuntu the simplest is apt install python3-psutil or alternatively need to install first the python-dev package and gcc (python-devel on Fedora/CentOS/RHEL). For Windows, just install psutil from the binary installation file.

By default, Glances is installed without the Web interface dependencies. To install it, use the following command:

.. code-block:: console

pip install --user 'glances[web]'

For a full installation (with all features):

.. code-block:: console

pip install --user 'glances[all]'

To upgrade Glances to the latest version:

.. code-block:: console

pip install --user --upgrade glances

The current develop branch is published to the test.pypi.org package index. If you want to test the develop version (could be instable), enter:

.. code-block:: console

pip install --user -i https://test.pypi.org/simple/ Glances

PyPI: PipX, the alternative way

Install PipX on your system (apt install pipx on Ubuntu).

Install Glances (with all features):

.. code-block:: console

pipx install 'glances[all]'

The glances script will be installed in the ~/.local/bin folder.

Docker: the cloudy way

Glances Docker images are availables. You can use it to monitor your server and all your containers !

Get the Glances container:

.. code-block:: console

docker pull nicolargo/glances:latest-full

The following tags are availables:

• latest-full for a full Alpine Glances image (latest release) with all dependencies
• latest for a basic Alpine Glances (latest release) version with minimal dependencies (FastAPI and Docker)
• dev for a basic Alpine Glances image (based on development branch) with all dependencies (Warning: may be instable)
• ubuntu-latest-full for a full Ubuntu Glances image (latest release) with all dependencies
• ubuntu-latest for a basic Ubuntu Glances (latest release) version with minimal dependencies (FastAPI and Docker)
• ubuntu-dev for a basic Ubuntu Glances image (based on development branch) with all dependencies (Warning: may be instable)

Run last version of Glances container in console mode:

.. code-block:: console

docker run --rm -e TZ="${TZ}" -v /var/run/docker.sock:/var/run/docker.sock:ro -v /run/user/1000/podman/podman.sock:/run/user/1000/podman/podman.sock:ro --pid host --network host -it nicolargo/glances:latest-full

By default, the /etc/glances/glances.conf file is used (based on docker-compose/glances.conf).

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

.. code-block:: console

FROM nicolargo/glances:latest
COPY glances.conf /root/.config/glances/glances.conf
CMD python -m glances -C /root/.config/glances/glances.conf $GLANCES_OPT

Alternatively, you can specify something along the same lines with docker run options (notice the GLANCES_OPT environment variable setting parameters for the glances startup command):

.. code-block:: console

docker run -e TZ="${TZ}" -v $HOME/.config/glances/glances.conf:/glances.conf:ro -v /var/run/docker.sock:/var/run/docker.sock:ro -v /run/user/1000/podman/podman.sock:/run/user/1000/podman/podman.sock:ro --pid host -e GLANCES_OPT="-C /glances.conf" -it nicolargo/glances:latest-full

Where $HOME/.config/glances/glances.conf is a local directory containing your glances.conf file.

Run the container in Web server mode:

.. code-block:: console

docker run -d --restart="always" -p 61208-61209:61208-61209 -e TZ="${TZ}" -e GLANCES_OPT="-w" -v /var/run/docker.sock:/var/run/docker.sock:ro -v /run/user/1000/podman/podman.sock:/run/user/1000/podman/podman.sock:ro --pid host nicolargo/glances:latest-full

For a full list of options, see the Glances Docker_ documentation page.

GNU/Linux package

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 and only basics plugins are enabled.

Note: The Debian package (and all other Debian-based distributions) do not include anymore the JS statics files used by the Web interface (see issue2021). If you want to add it to your Glances installation, follow the instructions: issue2021comment. In Glances version 4 and higher, the path to the statics file is configurable (see issue2612).

FreeBSD

To install the binary package:

.. code-block:: console

# pkg install py39-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 3.4+ ship with pip) and then run the following command:

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
