🧩 Problem

I wanted a centralized monitoring platform for my homelab that could monitor:

• On-premises VMware ESXi hosts
• Linux virtual machines
• Windows systems
• HPE iLO hardware management
• Cloud-hosted workloads

The challenge was that most of my infrastructure lives behind NAT at home, and I did not want to expose services publicly or configure complex port forwarding.

🛠️ Solution Overview

I built a hybrid monitoring architecture using:

• Zabbix 7.0 LTS hosted in Azure
• ZeroTier for secure private connectivity
• Zabbix Proxy running locally in my homelab
• VMware API monitoring for ESXi
• SNMP monitoring for HPE iLO

This design allows cloud-hosted monitoring while keeping home infrastructure private.

🧩 Problem

I attempted to install ESXi 8 on my Dell OptiPlex homelab machine, but during boot, I encountered a Pink Screen of Death (PSOD) with errors like:

• Fatal CPU mismatch on feature
• HW feature incompatibility detected

This prevented ESXi from installing or booting successfully. !

🛠️ Root Cause

The issue is caused by modern Intel CPUs (12th Gen and newer) using a hybrid architecture with:

• Performance cores (P-cores)
• Efficiency cores (E-cores)

ESXi expects uniform CPU cores, so it crashes when it detects different core types.
