监视 TCPv4\Segments Retransmitted/sec 性能计数器。
此监视器跟踪通过 TCPv4 每秒重新传输的段数。当重新传输的段数超过 TCPv4\Segments Retransmitted/sec 性能计数器的阈值时,监视器将切换至警告状态。
重新传输基于之前被认为正在传输的数据中的字节测量。当重新传输的段数不高时,网络性能不受影响。但是,过多的重新传输意味着由于连接故障、连接重置或硬件问题导致带宽明显减少。
调查导致连接失败的网络因素并解决所暴露的问题。高重新传输率还可能由硬件问题导致。因此,还必须进一步调查系统计数器,如处理器计数器。使用基线值来确定这些计数器超出范围并可能指示问题的时间。
