Property Value

Type: System.Int64
An Int64 value that specifies the total number of TCP connections initiated by clients.

IETF RFC 2012 formally defines this value as, "The number of times TCP connections have made a direct transition to the SYN-SENT state from the CLOSED state."

The following code example displays connection information.

Public Shared Sub ShowTcpConnectionStatistics() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim tcpstat As TcpStatistics = properties.GetTcpIPv4Statistics()

    Console.WriteLine("  Connection Data:")
    Console.WriteLine("      Current  ............................ : {0}", tcpstat.CurrentConnections)
    Console.WriteLine("      Cumulative .......................... : {0}", tcpstat.CumulativeConnections)
    Console.WriteLine("      Initiated ........................... : {0}", tcpstat.ConnectionsInitiated)
    Console.WriteLine("      Accepted ............................ : {0}", tcpstat.ConnectionsAccepted)
    Console.WriteLine("      Failed Attempts ..................... : {0}", tcpstat.FailedConnectionAttempts)
    Console.WriteLine("      Reset ............................... : {0}", tcpstat.ResetConnections)
    Console.WriteLine("      Errors .............................. : {0}", tcpstat.ErrorsReceived)
