Zabbix Windows GPU (AMD) – LibreHardwareMonitor HTTP Template

This template collects AMD GPU and hardware metrics on Windows using LibreHardwareMonitor JSON API (HTTP method).
It does not rely on WMI.

---

✅ Tested on

• AMD Radeon RX 9070 XT
• Windows 11
• Zabbix Agent 7.4
• Zabbix Server 7.4

---

📦 Requirements

• LibreHardwareMonitor
  https://github.com/LibreHardwareMonitor/LibreHardwareMonitor
• Zabbix Agent installed on the monitored host
• Network access from Zabbix Server/Proxy to port 8085

---

🚀 Installation

1️⃣ Install LibreHardwareMonitor

Download from: https://github.com/LibreHardwareMonitor/LibreHardwareMonitor

Or install via winget:

winget install LibreHardwareMonitor.LibreHardwareMonitor

---

2️⃣ Enable Web Server in LibreHardwareMonitor

Run LibreHardwareMonitor as Administrator:

Options → Remote Web Server → Run

Default port: 8085

Verify in browser:

http://localhost:8085/data.json

---

3️⃣ Allow Windows Firewall access

Run PowerShell as Administrator:

New-NetFirewallRule `
  -DisplayName "LibreHardwareMonitor Allow TCP" `
  -Direction Inbound `
  -LocalPort 8085 `
  -Protocol TCP `
  -Action Allow `
  -Profile Any

---

4️⃣ Import and Deploy Template

• Import template into Zabbix
• Link it to your Windows host
• Ensure host interface IP/DNS matches the monitored machine
• Make sure Zabbix Server/Proxy can access:

http://{HOST.CONN}:8085/data.json

---

⚙ How It Works

• Master item: lhm.json (HTTP agent)
• All hardware metrics are dependent items
• Data is parsed via JSONPath
• Values are normalized using:
  • RegEx
  • Comma → dot replacement

---

⚠ Important Notes

• JSONPath filters may vary depending on hardware
• Sensor IDs differ between:
  • GPU models
  • Motherboards
  • Storage devices
  • LHM versions

If metrics return empty values:

1. Open:

   http://localhost:8085/data.json
   

2. Locate correct SensorId
3. Adjust JSONPath in item preprocessing

---

🛠 Troubleshooting

Problem	Possible Cause
No data	LHM not running
Timeout	Firewall blocking port 8085
Unsupported item value	Wrong JSONPath
Works locally but not from Zabbix	LHM listening only on 127.0.0.1

---

💡 Tip

If JSONPath does not match your hardware layout:

• Inspect data.json
• Search for SensorId
• Adjust template accordingly

You can also use AI to generate correct JSONPath based on your data.json.
