.SH NAME
glances \- An eye on your system
.SH SYNOPSIS
.sp
\fBglances\fP [OPTIONS]
.SH DESCRIPTION
.sp
\fBglances\fP is a cross\-platform curses\-based monitoring tool that aims
to present a maximum of information in a minimum of space, ideally fitting
in a classic 80x24 terminal or larger for more details. It can adapt
dynamically to the displayed information depending on the terminal size.
It can also work in client/server mode.
Remote monitoring can be performed via a terminal or web interface.
.sp
\fBglances\fP is written in Python and uses the \fIpsutil\fP library to get
information from your system.

User\-specific options override system\-wide options, and options given on

.SH SYNTAX
.sp
Glances read configuration files in the \fIini\fP syntax.
.sp
A first section (called global) is available:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
[global]
# Refresh rate (default is a minimum of 2 seconds)
# Can be overwritten by the \-t <sec> option
# It is also possible to overwrite it in each plugin section
refresh=2
# Should Glances check if a newer version is available on PyPI ?
check_update=false
# History size (maximum number of values)
# Default is 28800: 1 day with 1 point every 3 seconds
history_size=28800
# Define directory external to glances hierarchy for loading additional plugins
# The layout follows the glances standard for plugin definitions
# (see <install\-dir>glances/plugins for details)
# plugin_dir=/home/user/dev/plugins
.ft P

.UNINDENT
.UNINDENT

Each plugin, export module, and application monitoring process (AMP) can
have a section. Below is an example for the CPU plugin:
.INDENT 0.0

an InfluxDB export module:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
[influxdb]
# Configuration for the \-\-export influxdb option
# https://influxdb.com/
host=localhost

user=root
password=root
db=glances
prefix=localhost
#tags=foo:bar,spam:eggs
.ft P

.UNINDENT
.UNINDENT
.sp
or a Nginx AMP:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
[amp_nginx]
# Nginx status page should be enabled (https://easyengine.io/tutorials/nginx/status\-page/)

.ft P

.UNINDENT
.UNINDENT

With Glances 3.0 or higher, you can use dynamic configuration values
by utilizing system commands. For example, if you want to set the prefix
of an InfluxDB export to the current hostname, use:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
[influxdb]
\&...
prefix=\(gahostname\(ga
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
Or if you want to add the Operating System name as a tag:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
[influxdb]
\&...
tags=system:\(gauname \-a\(ga
.ft P
.fi
.UNINDENT
.UNINDENT
.SH LOGGING
.sp
Glances logs all of its internal messages to a log file.
.sp
\fBDEBUG\fP messages can be logged using the \fB\-d\fP option on the command
line.
.sp
The location of the Glances log file depends on your operating system. You can
display the full path of the Glances log file using the \fBglances \-V\fP
command line.
.sp
The file is automatically rotated when its size exceeds 1 MB.
.sp
If you want to use another system path or change the log message, you
can use your logger configuration. First of all, you have to create
a \fBglances.json\fP file with, for example, the following content (JSON
format):
.INDENT 0.0
.INDENT 3.5
.sp
