TCPv6 Segments Sent Per Second

Microsoft.Windows.Server.10.0.TCPv6.SegmentsSentPerSec (UnitMonitor)

Monitors the TCPv6\Segments Sent/sec performance counter.

Knowledge Base article:

Summary

This monitor traces through the quantity of segments sent via TCPv6 per second (but excluding those containing only retransmitted bytes). When the quantity of sent segments exceeds the threshold for the TCPv6\Segments Sent/sec performance counter, the monitor is switched to warning state.

Causes

A sudden increase of the quantity of sent segments may indicate a security breach.

Resolutions

Take actions to eliminate security weak points.
