Step 6:- Add a firewall rule for Glances web port so that the web console would be accessible using the below command.
[root@linuxhelp ~]# firewall-cmd --zone=public --add-port=61208/tcp --permanent
success
[root@linuxhelp ~]# firewall-cmd --reload
success
Step 7: Run the below glances command to monitor your local machine.
[root@linuxhelp ~]# glances
Step 8: If you want to remotely monitor your machine, from any device with a web browser, just run the glances with the -w option.
For this to work, we need to install the Bottle module -- you can install this module using pip command.
[root@linuxhelp ~]# pip3 install bottle
Requirement already satisfied: bottle in /usr/lib/python3.9/site-packages (0.12.21)
WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv
Step 9: Run the below command to remotely monitor a machine
[root@linuxhelp ~]# glances -w
Glances Web User Interface started on http://0.0.0.0:61208/
Copy the above URL and paste in your web browser. Web mode will only be active if the above command is running. You can quit the web mode by stopping the web mode with Ctrl + C.
