TCPv4 每秒傳送的區段數

Microsoft.Windows.Server.10.0.TCPv4.SegmentsSentPerSec (UnitMonitor)

監視 TCPv4\Segments Sent/sec 效能計數器。

Knowledge Base article:

摘要

此監視器會追蹤每秒透過 TCPv4 傳送的區段數 (但排除那些僅包含重新傳送位元組的區段)。當傳送的區段數超過 TCPv4\Segments Sent/sec 效能計數器的閾值時，監視器會切換為警告狀態。

原因

傳送的區段數暴增可能表示發生安全性缺口。

解決方式

採取行動來填補安全性弱點。
