The default Proxmox Virtual Environment (PVE) dashboard lacks detailed system metric information like CPU and SSD temperatures.
To display temperature data on the PVE GUI, users need to install the lm-sensors package and edit specific Perl and JavaScript files.
In the Perl file Nodes.pm (/usr/share/perl5/PVE/API2/Nodes.pm), users need to add a line of code to fetch thermal state data using `sensors` command.
In the JavaScript file pvemanagerlib.js (/usr/share/pve-manager/js), users need to make changes to display the CPU thermal state with core temperatures and SSD device information.
