To generate performance statistics of a host, a physical or virtual component of the host is associated with network interface information corresponding to one or more physical or virtual network interface devices disposed in the host. The performance statistics of the physical or virtual component together with the associated network interface information are periodically transmitted. The network interface information may be a MAC address or an SNMP ifIndex associated with the physical or virtual network interface devices. The SNMP ifIndex may be used to retrieve a corresponding MAC address. The transmitted network interface information is used to analyze the performance statistics of the associated physical or virtual component. The performance statistic may represent a CPU usage, a memory usage, a disk usage, an I/O usage, power consumption, or temperature of the physical or virtual component.
