Configuration
=============

No configuration file is mandatory to use Glances.

Furthermore a configuration file is needed to access more settings.

Location
--------

You can put the ``glances.conf`` file in the following locations:

=========== ============================================================
``Linux``   ~/.config/glances, /etc/glances
``*BSD``    ~/.config/glances, /usr/local/etc/glances
``OS X``    ~/Library/Application Support/glances, /usr/local/etc/glances
``Windows`` %APPDATA%\glances
=========== ============================================================

On Windows XP, the ``%APPDATA%`` path is:

::

    C:\Documents and Settings\<User>\Application Data

Since Windows Vista and newer versions:

::

    C:\Users\<User>\AppData\Roaming

User-specific options override system-wide options and options given on
the command line override either.

Syntax
------

Glances reads configuration files in the *ini* syntax.

A first section (called global) is available:

.. code-block:: ini

    [global]
    # Does Glances should check if a newer version is available on Pypi ?
    check_update=true

Each plugin, export module and application monitoring process (AMP) can have a
section. Below an example for the CPU plugin:

.. code-block:: ini

    [cpu]
    user_careful=50
    user_warning=70
    user_critical=90
    iowait_careful=50
    iowait_warning=70
    iowait_critical=90
    system_careful=50
    system_warning=70
    system_critical=90
    steal_careful=50
    steal_warning=70
    steal_critical=90

an InfluxDB export module:

.. code-block:: ini

    [influxdb]
    # Configuration for the --export-influxdb option
    # https://influxdb.com/
    host=localhost
    port=8086
    user=root
    password=root
    db=glances
    prefix=localhost
    #tags=foo:bar,spam:eggs

or a NGinx AMP:

.. code-block:: ini

    [amp_nginx]
    # Nginx status page should be enable (https://easyengine.io/tutorials/nginx/status-page/)
    enable=true
    regex=\/usr\/sbin\/nginx
    refresh=60
    one_line=false
    status_url=http://localhost/nginx_status

Logging
-------

Glances logs all of its internal messages to a log file.

``DEBUG`` messages can been logged using the ``-d`` option on the command
line.

By default, the ``glances.log`` file is under the temporary directory:

===================== ==================================================
``Linux, *BSD, OS X`` /tmp
``Windows``           %APPDATA%\\Local\\temp
===================== ==================================================

If ``glances.log`` is not writable, a new file will be created and
returned to the user console.
