          ## Monitoring Capabilities by Device Type:
          
          ### ✅ Full Monitoring (Linux hosts with Netdata)
          - fedora (parent)
          - lenovo420, omv800, lenovo, surface, omvbackup (children)
          
          ### 📊 Limited Monitoring (ping, port checks)  
          - Router/gateway
          - Docker hosts
          - Network appliances
          
          ### ⚠️ Manual Monitoring Required
          - Windows machines (need WMI/SNMP setup)
          - Mobile devices (battery optimization prevents agents)
          - IoT devices (resource constrained)
