A toolset to gather temperature and power consumption metrics then collect in Prometheus. Can be found on GitHub https://github.com/jaroslawhartman/proxmox-monitoring/tree/main

Architecture

Components

• Proxmox Server 8.1.3

Host

Collecting script is running every minute on the pve host

* * * * * /root/scripts/temperature.sh > /dev/null 2>&1

Temperature of the disks (SSD and HDD) and CPU&MB collected by a bash script invoking smartctl and sensors. After parsing and formatting the sample is pushed to Prometheus Pushgateway.

Monitoring VM

Other monitoring components are installed as Docker containers insiide a VM.

• Shelly Smart Plug with power meter capabilities

Power consumption can be gathered using a REST request:

curl http://192.168.3.154/meter/0

{
 "power":86.46,
 "overpower":0.00,
 "is_valid":true,
 "timestamp":1703015868,
 "counters":[
    88.916,
    89.196,
    88.723
 ],
 "total":4928769
}
