Ariel Otilibili b537f454c1 Bumped minimal Python version to 3.9 
* Python 3.8 is now end of life [Link]
* changed occurrences found with `git grep -P '[^\d\.]3\.8[^\d]'`
* so doing, removed unused branch in `glances/outputs/glances_restful_api.py`
* branch introduced by f6545580db
* ruff also needs a bump; i.e, `s/py38/py39/`
* not done yet, since it needs to clear out warnings.

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

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

or in a JSON format thanks to the stdout-json option (attribute not supported in this mode in order to have a real JSON object in output):
.. code-block:: console
$ glances --stdout-json cpu,mem
cpu: {"total": 29.0, "user": 24.7, "nice": 0.0, "system": 3.8, "idle": 71.4, "iowait": 0.0, "irq": 0.0, "softirq": 0.0, "steal": 0.0, "guest": 0.0, "guest_nice": 0.0, "time_since_update": 1, "cpucore": 4, "ctx_switches": 0, "interrupts": 0, "soft_interrupts": 0, "syscalls": 0}
mem: {"total": 7837949952, "available": 2919079936, "percent": 62.8, "used": 4918870016, "free": 2919079936, "active": 2841214976, "inactive": 3340550144, "buffers": 546799616, "cached": 3068141568, "shared": 788156416}
