Glances is a free open supply, fashionable, cross-platform, real-time high and htop-like system monitoring device, which provides superior options in comparison with its counterparts, and may run in numerous modes: as a standalone, in consumer/server mode, and in internet server mode.
Contemplating the internet server mode, you don’t essentially must log into your distant server through SSH to run glances, you’ll be able to run it in internet server mode and entry it through an online browser to remotely monitor your Linux server, as defined under.
To run glances in internet server mode, it is advisable to set up it along with the Python bottle module, a quick, easy, and light-weight WSGI micro web-framework, utilizing the suitable command to your Linux distribution.
$ sudo apt set up glances python-bottle [On Debian, Ubuntu and Mint] $ sudo yum set up glances python-bottle [On RHEL/CentOS/Fedora and Rocky/AlmaLinux] $ sudo emerge -a sys-apps/glances python-bottle [On Gentoo Linux] $ sudo apk add glances python-bottle [On Alpine Linux] $ sudo pacman -S glances python-bottle [On Arch Linux] $ sudo zypper set up glances python-bottle [On OpenSUSE]
Alternatively, set up it utilizing the PIP command proven.
$ sudo pip set up bottle
Upon getting put in the above packages, launch glances with the -w flag to run it in internet server mode. By default, it would hear on port 61208.
$ glances -w OR $ glances -w &
In case you are operating firewalld companies, then you must open port 61208 to permit inbound site visitors to that port.
$ sudo firewall-cmd --permanent --add-port=61208/tcp $ sudo firewall-cmd --reload
For the UFW firewall, run these instructions.
$ sudo ufw permit 61208/tcp $ sudo ufw reload
After that, from an online browser, use the URL http://SERVER_IP:61208/ to entry the glances UI.
In case you are utilizing the systemd system and companies supervisor, you’ll be able to run glances in internet server mode as a service for environment friendly administration, as defined within the subsequent part. I really want this technique to run it as a background course of.
Run Glances in Net Server Mode as a Service
Begin by creating your service unit file (which I’ve most well-liked to call as glancesweb.service) below /usr/lib/systemd/system/glancesweb.service.
$ sudo vim /usr/lib/systemd/system/glancesweb.service
Then copy and paste the unit file configuration under in it.
[Unit] Description = Glances in Net Server Mode After = community.goal [Service] ExecStart = /usr/bin/glances -w -t 5 [Install] WantedBy = multi-user.goal
The above configuration tells systemd that it is a unit-of-type service, it ought to be loaded after the community.goal.
And as soon as the system is within the community goal, systemd will invoke the command “/usr/bin/glances -w -t 5” as a service. The -t specifies an interval for dwell updates in seconds.
The [install] part informs systemd that this service is needed by “multi-user.goal”. Due to this fact, once you allow it, a symbolic hyperlink is created from the /and so forth/systemd/system/multi-user.goal.needs/glancesweb.service to /usr/lib/systemd/system/glancesweb.service. Disabling it would delete this symbolic hyperlink.
Subsequent, allow your new systemd service, begin and examine its standing as follows.
$ sudo systemctl allow glancesweb.service $ sudo systemctl begin glancesweb.service $ sudo systemctl standing glancesweb.service
Lastly, out of your internet browser, use the URL http://SERVER_IP:61208/ to remotely monitor your Linux servers through the glances UI, on any system (smartphone, pill, or pc).
You’ll be able to change the refresh price of the web page, merely add the interval in seconds on the finish of the URL, this units the refresh price to 8 seconds.
http://SERVERI_P:61208/8
One draw back of operating glances in internet server mode is that, if the Web connection is poor the consumer tends to simply disconnect from the server.

That’s all! In case you have any questions or further info so as to add, use the remark type under.
