NAME
glances - An eye on your system
SYNOPSIS
glances [OPTIONS]
DESCRIPTION
glances is a cross-platform curses-based monitoring tool which aims to present a maximum
of information in a minimum of space, ideally to fit in a classical 80x24 terminal or
higher to have additional information. It can adapt dynamically the displayed information
depending on the terminal size. It can also work in client/server mode. Remote monitoring
could be done via terminal or web interface.
glances is written in Python and uses the psutil library to get information from your
system.

CONFIGURATION
No configuration file is mandatory to use Glances.
Furthermore a configuration file is needed to access more settings.
LOCATION
NOTE:
A template is available in the /usr{,/local}/share/doc/glances (Unix-like) directory or
directly on GitHub.
You can put your own glances.conf file in the following locations:
┌─────────────┬─────────────────────────────────┐
│Linux, SunOS │ ~/.config/glances, /etc/glances │
├─────────────┼─────────────────────────────────┤
│*BSD │ ~/.config/glances, │
│ │ /usr/local/etc/glances │
├─────────────┼─────────────────────────────────┤
│macOS │ ~/Library/Application │
│ │ Support/glances, │
│ │ /usr/local/etc/glances │
├─────────────┼─────────────────────────────────┤
│Windows │ %APPDATA%\glances │
└─────────────┴─────────────────────────────────┘
• On Windows XP, %APPDATA% is: C:\Documents and Settings\<USERNAME>\Application Data.
• On Windows Vista and later: C:\Users\<USERNAME>\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:
[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:
[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:
[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:
[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:
┌────────┬────────┐
│*nix │ /tmp │
├────────┼────────┤
│Windows │ %TEMP% │
└────────┴────────┘
• On Windows XP, %TEMP% is: C:\Documents and Settings\<USERNAME>\Local Settings\Temp.
• On Windows Vista and later: C:\Users\<USERNAME>\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):
{
"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:
LOG_CFG=<path>/glances.json glances
NOTE:
Replace <path> by the folder where your glances.json file is hosted.
EXAMPLES
Monitor local machine (standalone mode):
$ glances
Monitor local machine with the web interface (Web UI):
$ glances -w
Monitor local machine and export stats to a CSV file:
$ glances --export-csv
Monitor local machine and export stats to a InfluxDB server with 5s refresh time (also
possible to export to OpenTSDB, Cassandra, Statsd, ElasticSearch, RabbitMQ and Riemann):
$ glances -t 5 --export-influxdb
Start a Glances server (server mode):
$ glances -s
Connect Glances to a Glances server (client mode):
$ glances -c <ip_server>
Connect to a Glances server and export stats to a StatsD server:
$ glances -c <ip_server> --export-statsd
Start the client browser (browser mode):
$ glances --browser
