Network Interface Object

The Network Interface performance object consists of counters that measure the rates at which bytes and packets are sent and received over a TCP/IP connection. It includes counters that monitor connection errors.

Bytes Total/sec

Bytes Total/sec is the rate at which bytes are sent and received on the interface, including framing characters.

Detail Level: Advanced
Counter Type: PERF_COUNTER_COUNTER

Packets/sec

Packets/sec is the rate at which packets are sent and received on the network interface.

Detail Level: Advanced
Counter Type: PERF_COUNTER_COUNTER

Packets Received/sec

Packets Received/sec is the rate at which packets are received on the network interface.

Detail Level: Advanced
Counter Type: PERF_COUNTER_COUNTER

Packets Sent/sec

Packets Sent/sec is the rate at which packets are sent on the network interface.

Detail Level: Advanced
Counter Type: PERF_COUNTER_COUNTER

Current Bandwidth

Current Bandwidth is an estimate of the interface's current bandwidth 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.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Bytes Received/sec

Bytes Received/sec is the rate at which bytes are received on the interface, including framing characters.

Detail Level: Advanced
Counter Type: PERF_COUNTER_COUNTER

Packets Received Unicast/sec

Packets Received Unicast/sec is the rate at which (subnet) unicast packets are delivered to a higher-layer protocol.

Detail Level: Expert
Counter Type: PERF_COUNTER_COUNTER

Packets Received Non-Unicast/sec

Packets Received Non-Unicast/sec is the rate at which non-unicast (i.e., subnet broadcast or subnet multicast) packets are delivered to a higher-layer protocol.

Detail Level: Expert
Counter Type: PERF_COUNTER_COUNTER

Packets Received Discarded

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 being deliverable to a higher-layer protocol. One possible reason for discarding such a packet could be to free up buffer space.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Packets Received Errors

Packets Received Errors is the number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Packets Received Unknown

Packets Received Unknown is the number of packets received via the interface that were discarded because of an unknown or unsupported protocol.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Bytes Sent/sec

Bytes Sent/sec is the rate at which bytes are sent on the interface, including framing characters.

Detail Level: Advanced
Counter Type: PERF_COUNTER_COUNTER

Packets Sent Unicast/sec

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.

Detail Level: Expert
Counter Type: PERF_COUNTER_COUNTER

Packets Sent Non-Unicast/sec

Packets Sent Non-Unicast/sec is the rate at which packets are requested to be transmitted to non-unicast (i.e., subnet broadcast or subnet multicast) addresses by higher-level protocols. The rate includes the packets that were discarded or not sent.

Detail Level: Expert
Counter Type: PERF_COUNTER_COUNTER

Packets Outbound Discarded

Packets Outbound Discarded is the number of outbound packets that were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a packet could be to free up buffer space.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Packets Outbound Errors

Packets Outbound Errors is the number of outbound packets that could not be transmitted because of errors.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT

Output Queue Length

Output Queue Length is the length of the output packet queue (in packets.) If this is longer than 2, delays are being experienced and the bottleneck should be found and eliminated if possible. Since the requests are queued by NDIS in this implementations, this will always be 0.

Detail Level: Advanced
Counter Type: PERF_COUNTER_RAWCOUNT
