The Network Adapter performance object consists of counters that measure the rates at which bytes and packets are sent and received over a physical or virtual network connection. It includes counters that monitor connection errors.
'Bytes Received/sec is the rate at which bytes are received over each network adapter, including framing characters. Network Interface\Bytes Received/sec is a subset of Network Interface\Bytes Total/sec.'
'Bytes Sent/sec is the rate at which bytes are sent over each network adapter, including framing characters. Network Interface\Bytes Sent/sec is a subset of Network Interface\Bytes Total/sec.'
'Bytes Total/sec is the rate at which bytes are sent and received over each network adapter, including framing characters. Network Interface\Bytes Total/sec is a sum of Network Interface\Bytes Received/sec and Network Interface\Bytes Sent/sec.'
'Current Bandwidth is an estimate of the current bandwidth of the network interface in bits per second (BPS). For interfaces that do not vary in bandwidth or for those where no accurate estimation can be made, this value is the nominal bandwidth.'
'Offloaded Connections is the number of TCP connections (over both IPv4 and IPv6) that are currently handled by the TCP chimney offload capable network adapter.'
'Output Queue Length is the length of the output packet queue (in packets). If this is longer than two, there are delays and the bottleneck should be found and eliminated, if possible. Since the requests are queued by the Network Driver Interface Specification (NDIS) in this implementation, this will always be 0.'
'Packets Outbound Discarded is the number of outbound packets that were chosen to be discarded even though no errors had been detected to prevent transmission. One possible reason for discarding packets could be to free up buffer space.'
'Packets Received Discarded is the number of inbound packets that were chosen to be discarded even though no errors had been detected to prevent their delivery to a higher-layer protocol. One possible reason for discarding packets could be to free up buffer space.'
'Packets Received Non-Unicast/sec is the rate at which non-unicast (subnet broadcast or subnet multicast) packets are delivered to a higher-layer protocol.'
'Packets Sent Non-Unicast/sec is the rate at which packets are requested to be transmitted to non-unicast (subnet broadcast or subnet multicast) addresses by higher-level protocols. The rate includes the packets that were discarded or not sent.'
'Packets Sent Unicast/sec is the rate at which packets are requested to be transmitted to subnet-unicast addresses by higher-level protocols. The rate includes the packets that were discarded or not sent.'
'TCP Active RSC Connections is the number of TCP connections (over both IPv4 and IPv6) that are currently receiving large packets from the RSC capable network adapter on this network interface.'
'The Name property defines the label by which the statistic or metric is known. When subclassed, the property can be overridden to be a Key property. '
