Components

1. 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.

2. Shelby Smart Plug with power meter capabilities

https://www.shelly.com/en/products/shop/shelly-plus-plug-s

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
}
