TCPv4 & TCPv6\Connections Established
The Connections Established counter is the total number of TCP connections in the ESTABLISHED state at the end of the measurement interval. The number of TCP connections that can be established is constrained by the size of the Nonpaged pool. When the Nonpaged pool is depleted, no new connections can be established.
Trending and forecasting analysis on this counter can be done to ensure that the system is properly scaled to handle future growth. The server can be tuned using the TCP registry entries like MaxHashTableSize and NumTcTablePartitions based on the number of network users seen on average.
