.. _quickstart: Quickstart ========== This page gives a good introduction in how to get started with Glances. Glances offers 3 modes: - Standalone - Client/Server - Web server Standalone Mode --------------- If you want to monitor your local machine, open a console/terminal and simply run: .. code-block:: console $ glances Glances should start (press 'q' or 'ESC' to exit): .. image:: _static/screenshot-wide.png It is also possible to display RAW JSON stats directly to stdout using: .. 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 2018-12-08 22:04:20 CEST,7.3,5948149760,4,1.04,0.99,1.04 2018-12-08 22:04:23 CEST,5.4,5949136896,4,1.04,0.99,1.04 ... Note: It will display one line per stat per refresh. Client/Server Mode ------------------ If you want to remotely monitor a machine, called ``server``, from another one, called ``client``, just run on the server: .. code-block:: console server$ glances -s and on the client: .. code-block:: console client$ glances -c @server where ``@server`` is the IP address or hostname of the server. In server mode, you can set the bind address with ``-B ADDRESS`` and the listening TCP port with ``-p PORT``. In client mode, you can set the TCP port of the server with ``-p PORT``. Default binding address is ``0.0.0.0`` (Glances will listen on all the available network interfaces) and TCP port is ``61209``. In client/server mode, limits are set by the server side. You can set a password to access to the server using the ``--password``. By default, the username is ``glances`` but you can change it with ``--username``. If you want, the SHA password will be stored in ``username.pwd`` file. Next time your run the server/client, password will not be asked. To set a specific username you can used the -u option. It is also possible to set the password in the Glances configuration file: .. code-block:: ini [passwords] # Define the passwords list # Syntax: host=password # Where: host is the hostname # password is the clear password # Additionally (and optionally) a default password could be defined localhost=mylocalhostpassword default=mydefaultpassword Central client ^^^^^^^^^^^^^^ .. image:: _static/browser.png Glances can centralize available Glances servers using the ``--browser`` option. The server list can be statically defined via the configuration file (section ``[serverlist]``). Example: .. code-block:: ini [serverlist] # Define the static servers list server_1_name=xps server_1_alias=xps server_1_port=61209 server_2_name=win server_2_port=61235 Glances can also detect and display all Glances servers available on your network via the ``zeroconf`` protocol (not available on Windows): To start the central client, use the following option: .. code-block:: console client$ glances --browser .. note:: Use ``--disable-autodiscover`` to disable the auto discovery mode. When the list is displayed, you can navigate through the Glances servers with up/down keys. It is also possible to sort the server using: - '1' is normal (do not sort) - '2' is using sorting with ascending order (ONLINE > SNMP > PROTECTED > OFFLINE > UNKNOWN) - '3' is using sorting with descending order (UNKNOW > OFFLINE > PROTECTED > SNMP > ONLINE) SNMP ^^^^ As an experimental feature, if Glances server is not detected by the client, the latter will try to grab stats using the ``SNMP`` protocol: .. code-block:: console client$ glances -c @snmpserver .. note:: Stats grabbed by SNMP request are limited and OS dependent. A SNMP server should be installed and configured... IPv6 ^^^^ Glances is ``IPv6`` compatible. Just use the ``-B ::`` option to bind to all IPv6 addresses. Web Server Mode --------------- .. image:: _static/screenshot-web.png If you want to remotely monitor a machine, called ``server``, from any device with a web browser, just run the server with the ``-w`` option: .. code-block:: console server$ glances -w then on the client enter the following URL in your favorite web browser: :: http://@server:61208 where ``@server`` is the IP address or hostname of the server. To change the refresh rate of the page, just add the period in seconds at the end of the URL. For example, to refresh the page every ``10`` seconds: :: http://@server:61208/10 The Glances web interface follows responsive web design principles.
