TcpStatistics Class
Visual Studio 2010
Provides Transmission Control Protocol (TCP) statistical data.
Assembly: System (in System.dll)
The TcpStatistics type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | ConnectionsAccepted | Gets the number of accepted Transmission Control Protocol (TCP) connection requests. |
![]() | ConnectionsInitiated | Gets the number of Transmission Control Protocol (TCP) connection requests made by clients. |
![]() | CumulativeConnections | Specifies the total number of Transmission Control Protocol (TCP) connections established. |
![]() | CurrentConnections | Gets the number of current Transmission Control Protocol (TCP) connections. |
![]() | ErrorsReceived | Gets the number of Transmission Control Protocol (TCP) errors received. |
![]() | FailedConnectionAttempts | Gets the number of failed Transmission Control Protocol (TCP) connection attempts. |
![]() | MaximumConnections | Gets the maximum number of supported Transmission Control Protocol (TCP) connections. |
![]() | MaximumTransmissionTimeout | Gets the maximum retransmission time-out value for Transmission Control Protocol (TCP) segments. |
![]() | MinimumTransmissionTimeout | Gets the minimum retransmission time-out value for Transmission Control Protocol (TCP) segments. |
![]() | ResetConnections | Gets the number of RST packets received by Transmission Control Protocol (TCP) connections. |
![]() | ResetsSent | Gets the number of Transmission Control Protocol (TCP) segments sent with the reset flag set. |
![]() | SegmentsReceived | Gets the number of Transmission Control Protocol (TCP) segments received. |
![]() | SegmentsResent | Gets the number of Transmission Control Protocol (TCP) segments re-sent. |
![]() | SegmentsSent | Gets the number of Transmission Control Protocol (TCP) segments sent. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
Instances of this class are returned by the GetTcpIPv4Statistics and GetTcpIPv6Statistics methods, to give applications access to TCP traffic information.
The information in this class correlates to the management information objects described in http://www.ietf.org/rfc/rfc2012.txt.
The following code example displays the TCP statistics for the specified address family.
void ShowTcpStatistics( NetworkInterfaceComponent version ) { IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties(); TcpStatistics ^ tcpstat = nullptr; Console::WriteLine( "" ); switch ( version ) { case NetworkInterfaceComponent::IPv4: tcpstat = properties->GetTcpIPv4Statistics(); Console::WriteLine( "TCP/IPv4 Statistics:" ); break; case NetworkInterfaceComponent::IPv6: tcpstat = properties->GetTcpIPv6Statistics(); Console::WriteLine( "TCP/IPv6 Statistics:" ); break; default: throw gcnew ArgumentException( "version" ); break; } Console::WriteLine( " Minimum Transmission Timeout............. : {0}", tcpstat->MinimumTransmissionTimeout ); Console::WriteLine( " Maximum Transmission Timeout............. : {0}", tcpstat->MaximumTransmissionTimeout ); 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( "" ); Console::WriteLine( " Segment Data:" ); Console::WriteLine( " Received ........................... : {0}", tcpstat->SegmentsReceived ); Console::WriteLine( " Sent ................................ : {0}", tcpstat->SegmentsSent ); Console::WriteLine( " Retransmitted ....................... : {0}", tcpstat->SegmentsResent ); Console::WriteLine( "" ); }
