适用于:Windows Server(半年频道)、Windows Server 2016Applies to: Windows Server (Semi-Annual Channel), Windows Server 2016

本主题列出了与管理网络性能相关的计数器,其中包含以下各节。This topic lists the counters that are relevant to managing network performance, and contains the following sections.

资源利用率Resource Utilization

以下性能计数器与网络资源利用率相关。The following performance counters are relevant to network resource utilization.

  • IPv4、IPv6IPv4, IPv6

    • 每秒接收的数据报Datagrams Received/sec

    • 发送的数据报/秒Datagrams Sent/sec

  • TCPv4、TCPv6TCPv4, TCPv6

    • 每秒接收的段数Segments Received/sec

    • 发送的段数/秒Segments Sent/sec

    • 重新传输的段数/秒Segments Retransmitted/sec

  • 网络接口 ( * ) 、网络适配器 (*) Network Interface(*), Network Adapter(*)

    • 收到的字节数/秒Bytes Received/sec

    • 发送的字节数/秒Bytes Sent/sec

    • Packets Received/secPackets Received/sec

    • Packets Sent/secPackets Sent/sec

    • 输出队列长度Output Queue Length

      此计数器是数据包中的输出数据包队列的长度 ( ) 。This counter is the length of the output packet queue (in packets). 如果此长度大于2,则会发生延迟。If this is longer than 2, delays occur. 你应发现瓶颈,并在可能的情况中消除它。You should find the bottleneck and eliminate it if you can. 由于 NDIS 将请求排队,因此此长度应始终为0。Because NDIS queues the requests, this length should always be 0.

  • 处理器信息Processor Information

    • 处理器时间百分比% Processor Time

    • 中断数/秒Interrupts/sec

    • Dpc 排队/秒DPCs Queued/sec

      此计数器是将 Dpc 添加到逻辑处理器的 DPC 队列的平均速率。This counter is an average rate at which DPCs were added to the logical processor's DPC queue. 每个逻辑处理器都有其自己的 DPC 队列。Each logical processor has its own DPC queue. 此计数器测量将 Dpc 添加到队列的速率,而不是队列中 Dpc 的数目。This counter measures the rate at which DPCs are added to the queue, not the number of DPCs in the queue. 它显示最近两个样本中观测到的值之间的差异除以样本间隔的持续时间。It displays the difference between the values that were observed in the last two samples, divided by the duration of the sample interval.

潜在网络问题Potential Network Problems

以下性能计数器与潜在的网络问题相关。The following performance counters are relevant to potential network problems.

  • 网络接口 ( * ) 、网络适配器 (*) Network Interface(*), Network Adapter(*)

    • 放弃的已接收数据包Packets Received Discarded

    • 已接收的数据包错误Packets Received Errors

    • 放弃的出站数据包Packets Outbound Discarded

  • WFPv4, WFPv6WFPv4, WFPv6

    • 丢弃的数据包数/秒Packets Discarded/sec
  • UDPv4, UDPv6UDPv4, UDPv6

    • 数据报收到错误Datagrams Received Errors
  • TCPv4、TCPv6TCPv4, TCPv6

    • 连接失败Connection Failures

    • 低资源接收指示数/秒Low Resource Receive Indications/sec

    • 低资源接收的数据包数/秒Low Resource Received Packets/sec

  • Microsoft Winsock BSPMicrosoft Winsock BSP

    • 丢弃的数据报Dropped Datagrams

    • 丢弃的数据报/秒Dropped Datagrams/sec

    • 拒绝的连接Rejected Connections

    • 拒绝的连接数/秒Rejected Connections/sec
