Monitoring CPU Temperature and Fan RPM Using the sensors Command in the Proxmox Shell, Retrieving Data via the Proxmox API, and Recording it in Zabbix

[ramin110]

Hello everyone,

I am currently using the l-sensors command to read CPU temperature within a Proxmox environment, and I would like to monitor these values on my Zabbix server. However, I’m unsure how to use the Proxmox API to execute the sensors command, retrieve its output in JSON format, and forward it to the Zabbix server for storage and monitoring.

I have already set up Proxmox-Zabbix communication using the Zabbix template for Proxmox, including all necessary credentials and connection configurations, so this part is not an issue.

Any guidance on how to achieve this would be greatly appreciated.

Thanks in advance for your help!

Best regards,
Ramin

Used these section and it worked.

#!/bin/bash

# Define the Zabbix server and host
ZABBIX_SERVER="<ZABBIX_SERVER_IP>"
ZABBIX_HOST="<Proxmox_Host_Name>"

# Extract the package temperatures for both CPUs
cpu_temp_1=$(sensors | grep -E "Package id 0" | awk '{print $4}' | tr -d '+°C')
cpu_temp_2=$(sensors | grep -E "Package id 1" | awk '{print $4}' | tr -d '+°C')

# Check if we got valid temperatures for both CPUs
if [[ -z "$cpu_temp_1" || -z "$cpu_temp_2" ]]; then
echo "Error: CPU temperatures not found"
exit 1
fi

# Send each CPU temperature to Zabbix as a float
zabbix_sender -z "$ZABBIX_SERVER" -s "$ZABBIX_HOST" -k "cpu.temperature.package1" -o "$cpu_temp_1"
zabbix_sender -z "$ZABBIX_SERVER" -s "$ZABBIX_HOST" -k "cpu.temperature.package2" -o "$cpu_temp_2"





Create Zabbix Items:

• Go to Configuration → Hosts → Items.
• For CPU 1:
  • Name: CPU 1 Temperature (Package)
  • Key: cpu.temperature.package1
  • Type: Zabbix trapper
  • Type of information: Numeric (float)
• For CPU 2:
  • Name: CPU 2 Temperature (Package)
  • Key: cpu.temperature.package2
  • Type: Zabbix trapper
  • Type of information: Numeric (float)

crontab -e
