'Device Power State is the current power state of the network interface card. Power state 0 is the active operating state, while power state 3 is the device's lowest power state. Intermediate states 1 and 2 are device-specific sleep states. For example, a USB NIC uses power state 2 to allow remote-wakeup.'
'Low Power Transitions (Lifetime) measures the number of successful low-power transitions over the lifetime of the network interface card. The counter includes only transitions from the active high-power state to a low-power state.'
'% Time Suspended (Instantaneous) measures the amount of time that the network interface card is in a low-power suspended state. The percentage is calculated over the duration of the sample interval.'
'% Time Suspended (Lifetime) measures the amount of time that the network interface card is in a low-power suspended state. The percentage is calculated over the entire lifetime of the network card.'
