TEMPer Zabbix

Zabbix template and script to monitor temperatures returned by a TEMPer usb stick. This could be useful to check datacenter temperature or as a remote thermometer plugged to a raspberry pi.

Tested up to Zabbix 7.0.x

Requirement

• A TEMPer usb stick
• urwen's temper.py script : https://github.com/urwen/temper
• A working Zabbix client with a configured Zabbix agent.
• For the zabbix_sender way:
  • jq
  • zabbix sender

Setup

On Zabbix server

• Import the template on the server, then add it to the host equipped with the TEMPer usb device.
  • template_temper.xml for the regular pull way (Server will ask agent, recommended)
  • template_temper_sender.xml for the push way (Agent will push data to the server)

On Zabbix client

mkdir -p /etc/zabbix/scripts

• Install urwen's script into the /etc/zabbix/scripts directory
• Adjust permissions
  • chown -R zabbix: /etc/zabbix/scripts/
  • chmod +x /etc/zabbix/scripts/temper/temper.py

Pull way (recommended)

If needed, add a system.run key in the AllowKey config of your Zabbix Agent.

Push way

• Install this current script into the same directory

git clone https://github.com/ThibautPlg/TEMPer-Zabbix.git

mv TEMPer-Zabbix/TEMPer_zabbix.sh /etc/zabbix/scripts/

chown -R zabbix: /etc/zabbix/scripts/
chmod +x /etc/zabbix/scripts/TEMPer_zabbix.sh

• Customize TEMPer_zabbix.sh to match your environment if needed

vim /etc/zabbix/scripts/TEMPer_zabbix.sh

• Add a crontab entry (user zabbix or root required)
