Node sensor readings view

Compatibility:

• 9.0-9.2. Newer versions may often work
• Older version (7.x-8.x), use git version from Apr 6th 2025

This bash script installs a modification to the Proxmox Virtual Environment (PVE) web user interface (UI) to display sensor readings in a flexible and readable manner. The following readings are possible:

• CPU, NVMe/HDD/SSD temperatures (Celsius/Fahrenheit), fan speeds, ram temperatures via lm-sensors. Note: Hdds require kernel module drivetemp module installed.
• UPS information via Network Monitoring Tool
• Motherboard information or system information via dmidecode

How it works

The modification involves the following steps:

1. Backup original files in the home directory/backup
   • /usr/share/pve-manager/js/pvemanagerlib.js
   • /usr/share/perl5/PVE/API2/Nodes.pm
2. Patch Nodes.pm to enable readings.
3. Modify pvemanagerlib.js to:
   • Expand the node status view to full browser width.
   • Add reading (depending on & selections).
   • Allow collapsing the panel vertically.
4. Restart the pveproxy service to apply changes.

The script provides three options:

Option	Description
install	Apply the modification.
uninstall	Restore original files from backups.
save-sensors-data	Save a local copy of detected sensor data for reference or troubleshooting.

Notes:

• UPS support in multi-node setups require identical login credentials across nodes. This has not been fully tested.
• Proxmox upgrades may overwrite modified files; reinstallation of this mod could be required.

Install

Instructions be performed as 'root', as normal users do not have access to the files.

apt-get install lm-sensors
# lm-sensors must be configured, run below to configure your sensors, apply temperature offsets. Refer to lm-sensors manual for more information.
sensors-detect 
wget https://raw.githubusercontent.com/Meliox/PVE-mods/refs/heads/main/legacy-scripts/pve-mod-gui-sensors.sh
bash pve-mod-gui-sensors.sh install
# Then clear the browser cache to ensure all changes are visualized.

Additionally, adjustments are available in the first part of the script, where paths can be edited, cpucore offset and display information.

Nag screen deactivation

(Tested compatibility: 7.x - 8.3.5) This bash script installs a modification to the Proxmox Virtual Environment (PVE) web user interface (UI) which deactivates the subscription nag screen.

The modification includes two main steps:

1. Create backups of the original files in the backup directory relative to the script location.
2. Modify code.

The script provides three options:

Option	Description
install	Installs the modification by applying the necessary changes.
uninstall	Removes the modification by restoring the original files from backups.

Install

Instructions be performed as 'root', as normal users do not have access to the files.

wget https://raw.githubusercontent.com/Meliox/PVE-mods/refs/heads/main/legacy-scripts/pve-mod-nag-screen.sh
bash pve-mod-nag-screen.sh install

Script to update all containers

(Tested compatibility: 7.x - 8.3.5)

This script updates all running Proxmox containers, skipping specified excluded containers, and generates a separate log file for each container. The script first updates the Proxmox host system, then iterates through each container, updates the container, and reboots it if necessary. Each container's log file is stored in $log_path and the main script log file is named container-upgrade-main.log.

Install

wget https://raw.githubusercontent.com/Meliox/PVE-mods/refs/heads/main/legacy-scripts/updateallcontainers.sh

Or use git clone. Can be added to cron for e.g. monthly update: 0 6 1 * * /root/scripts/updateallcontainers.sh
