Certainly! Here's a concise summary of the steps to monitor CPU temperature with Zabbix using lm-sensors:

===== Install lm-sensors =====

Make sure lm-sensors is installed on the system where you want to monitor CPU temperature. You can typically install it using your system's package manager.

===== Create sensors.conf =====

Create a `sensors.conf` file with the necessary `UserParameter` configuration to fetch CPU temperature data. Place this file in a location where Zabbix Agent can access it. For example, ''/etc/zabbix/zabbix_agent2.d/sensors.conf'' :
   UserParameter=Temperature.CPU1,/usr/share/zabbix-agent/getCPUTemp.sh

===== Create the .sh Script =====

Create a shell script (e.g., `getCPUTemp.sh`) with the following content to extract and format the CPU temperature:

   #!/bin/bash
   sensors | grep -i package | awk -F'[+|°]' '{print $2}' | awk '{printf "%.1f", $1}'

===== Make the Script Executable =====

Ensure the script is executable by running:

   chmod +x /usr/share/zabbix-agent/getCPUTemp.sh

===== Restart Zabbix Agent =====

Restart the Zabbix Agent to apply the changes:

   service zabbix-agent restart


===== Configure Zabbix Item =====

In the Zabbix web interface, create a new item for CPU temperature monitoring:
  * **Name**: Give it a descriptive name, e.g., "CPU Temperature."
  * **Key**: Use the `Temperature.CPU1` key.
  * **Type**: Select "Zabbix Agent."
  * **Data type**: Choose "Numeric (float)."

===== Monitor CPU Temperature =====

After configuring the item, Zabbix will start collecting CPU temperature data, which you can view and use for monitoring within the Zabbix interface.

By following these steps, you can successfully monitor CPU temperature using Zabbix and lm-sensors.
