# Network Counters

Performance counters are modeled using the PerfCounterInfo data object type. Each instance of a PerfCounterInfo data object contains metadata about a specific metric available from the system. The net group of performance counters tracks network utilization for both physical and virtual NICs (network interface controllers) and other network devices, such as the virtual switches (vSwitch) that support connectivity among all components (virtual machines, VMkernel, host, and so on).
