Network Interface Object

Object: Network Interface Index: 510 Advanced

The Network Interface Object Type includes those counters that describe the rates that bytes and packets are received and sent over a Network TCP/IP connection. It also describes various error counts for the same connection.

Bytes Received/sec Advanced

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

Index: 264 Default Scale: 0.0001

Counter Type: PERF_COUNTER_COUNTER Counter Size: 4 bytes

Bytes Sent/sec Advanced

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

Index: 506 Default Scale: 0.0001

Counter Type: PERF_COUNTER_COUNTER Counter Size: 4 bytes

Bytes Total/sec Advanced

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

Index: 388 Default Scale: 0.0001

Counter Type: PERF_COUNTER_COUNTER Counter Size: 4 bytes

Current Bandwidth Advanced

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.

Index: 520 Default Scale: 0.000001

Counter Type: PERF_COUNTER_RAWCOUNT Counter Size: 4 bytes

Output Queue Length Advanced

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 implementation, this will always be 0.

Index: 544 Default Scale: 1

Counter Type: PERF_COUNTER_RAWCOUNT Counter Size: 4 bytes

Packets Outbound Discarded Advanced

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.

Index: 540 Default Scale: 1

Counter Type: PERF_COUNTER_RAWCOUNT Counter Size: 4 bytes

Packets Outbound Errors Advanced

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

Index: 542 Default Scale: 1

Counter Type: PERF_COUNTER_RAWCOUNT Counter Size: 4 bytes

Packets Received Discarded Advanced

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.

Index: 528 Default Scale: 1

Counter Type: PERF_COUNTER_RAWCOUNT Counter Size: 4 bytes

Packets Received Errors Advanced

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

Index: 530 Default Scale: 1

Counter Type: PERF_COUNTER_RAWCOUNT Counter Size: 4 bytes

Packets Received Non-Unicast/sec Expert

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

Index: 526 Default Scale: 0.1

Counter Type: PERF_COUNTER_COUNTER Counter Size: 4 bytes

Packets Received Unicast/sec Expert

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

Index: 524 Default Scale: 0.1

Counter Type: PERF_COUNTER_COUNTER Counter Size: 4 bytes

Packets Received Unknown Advanced

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

Index: 532 Default Scale: 1

Counter Type: PERF_COUNTER_RAWCOUNT Counter Size: 4 bytes

Packets Received/sec Advanced

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

Index: 266 Default Scale: 0.1

Counter Type: PERF_COUNTER_COUNTER Counter Size: 4 bytes

Packets Sent/sec Advanced

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

Index: 452 Default Scale: 0.1

Counter Type: PERF_COUNTER_COUNTER Counter Size: 4 bytes

Packets Sent Non-Unicast/sec Expert

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

Index: 538 Default Scale: 0.1

Counter Type: PERF_COUNTER_COUNTER Counter Size: 4 bytes

Packets Sent Unicast/sec Expert

Packets Sent Unicast/sec is the rate that 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.

Index: 536 Default Scale: 0.1

Counter Type: PERF_COUNTER_COUNTER Counter Size: 4 bytes

Packets/sec Advanced

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

Index: 400 Default Scale: 0.1

Counter Type: PERF_COUNTER_COUNTER Counter Size: 4 bytes
