.. _config:
Configuration
=============
No configuration file is mandatory to use Glances.
Furthermore a configuration file is needed to access more settings.
Location
--------
A template is available in the /usr/local/share/doc/glances folder
(on GNU/Linux OS) or directly in the Github:
https://raw.githubusercontent.com/nicolargo/glances/master/conf/glances.conf
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-USERNAME.log`` file is under the temporary directory:
===================== ==================================================
``Linux, *BSD, OS X`` /tmp
``Windows`` %APPDATA%\\Local\\temp
===================== ==================================================
If you want to use another system path or change the log message, you can use
your own logger configuration. First of all you have to create a glances.json
file with (for example) the following content (JSON format):
.. code-block:: json
{
"version": 1,
"disable_existing_loggers": "False",
"root": {
"level": "INFO",
"handlers": ["file", "console"]
},
"formatters": {
"standard": {
"format": "%(asctime)s -- %(levelname)s -- %(message)s"
},
"short": {
"format": "%(levelname)s: %(message)s"
},
"free": {
"format": "%(message)s"
}
},
"handlers": {
"file": {
"level": "DEBUG",
"class": "logging.handlers.RotatingFileHandler",
"formatter": "standard",
"filename": "/var/tmp/glances.log"
},
"console": {
"level": "CRITICAL",
"class": "logging.StreamHandler",
"formatter": "free"
}
},
"loggers": {
"debug": {
"handlers": ["file", "console"],
"level": "DEBUG"
},
"verbose": {
"handlers": ["file", "console"],
"level": "INFO"
},
"standard": {
"handlers": ["file"],
"level": "INFO"
},
"requests": {
"handlers": ["file", "console"],
"level": "ERROR"
},
"elasticsearch": {
"handlers": ["file", "console"],
"level": "ERROR"
},
"elasticsearch.trace": {
"handlers": ["file", "console"],
"level": "ERROR"
}
}
}
and start Glances using the following command line:
.. code-block:: console
LOG_CFG=<path>/glances.json glances
Note: Replace <path> by the folder where your glances.json file is hosted.
