Zabbix Traffic Light

Setup

1. Buy a USB traffic light - in our case we used this one

2. Install a host-system to trigger the traffic-light - in our case we needed an x86-bit linux/raspbian as the cli-binary only supported that architecture

3. Make sure you can trigger its lights manually using the shell

4. Make sure the host-system can access the Zabbix Server web-interface (firewalling)

5. Create an API user

   • See: Zabbix Docs
   • You may need to create a custom user-role: Zabbix Docs
   • Groups: Readers
   • Permissions:
     • User-type: User
     • Permissions: Read access on groups you want to 'display'

6. Copy the script to the host-system and update/modify the variables as needed:

   • API_URL, API_USER, API_PWD
   • AMPEL_CMD => path to your executable
   • CHOICES => map the zabbix trigger priority to commands

7. Install the requirements

   python3 -m pip install pyzabbix

8. Add a service to run the script

   cp ampel.service /etc/systemd/system/
   systemctl daemon-reload
   systemctl enable ampel.service
   systemctl start ampel.service
   systemctl status ampel.service
