The RAS_PORT_STATISTICS structure reports the statistics that a RAS
server collects for a connected port. The RAS server resets the various
statistic counters each time the port is connected. You can call the RasAdminPortClearStatistics
function to force the RAS server to reset the statistic counters.
For a port that is part of a multilink connection, this structure provides two
sets of statistics. The first set contains the cumulative statistics for all
ports in the connection. These statistics are the same for all ports in the
connection. The second set contains the statistics for just this port. If the
port is not part of a multilink connection, both sets of statistics have the
same information. To determine whether a port is part of a multilink
connection, check the PORT_MULTILINKED bit in the Flags member of the
port’s RAS_PORT_0 structure.

Members
-
dwBytesXmited
-
Specifies the total number of bytes transmitted by the connection.
-
dwBytesRcved
-
Specifies the total number of bytes received by the connection.
-
dwFramesXmited
-
Specifies the total number of frames transmitted by the connection.
-
dwFramesRcved
-
Specifies the total number of frames received by the connection.
-
dwCrcErr
-
Specifies the total number of CRC errors on the connection. CRC errors are
caused by the failure of a cyclic redundancy check. A CRC error indicates that
one or more characters in the data packet received were found garbled on
arrival.
-
dwTimeoutErr
-
Specifies the total number of time-out errors on the connection. Time-out
errors occur when an expected character is not received in time. When this
occurs, the software assumes that the data has been lost and requests that it
be resent.
-
dwAlignmentErr
-
Specifies the total number of alignment errors on the connection. Alignment
errors occur when a character received is not the one expected. This usually
happens when a character is lost or when a time-out error occurs.
-
dwHardwareOverrunErr
-
Specifies the total number of hardware overrun errors on the connection. These
errors indicate the number of times the sending computer has transmitted
characters faster than the receiving computer hardware can process them. If
this problem persists, reduce the BPS connection rate on the client.
-
dwFramingErr
-
Specifies the total number of framing errors on the connection. A framing
error occurs when an asynchronous character is received with an invalid start
or stop bit.
-
dwBufferOverrunErr
-
Specifies the total number of buffer overrun errors on the connection. A
buffer overrun error occurs when the sending computer is transmitting
characters faster than the receiving computer can accommodate them. If this
problem persists, reduce the BPS connection rate on the client.
-
dwBytesXmitedUncompressed
-
Specifies the total number of bytes transmitted uncompressed by the
connection.
-
dwBytesRcvedUncompressed
-
Specifies the total number of bytes received uncompressed by the connection.
-
dwBytesXmitedCompressed
-
Specifies the total number of bytes transmitted compressed by the connection.
-
dwBytesRcvedCompressed
-
Specifies the total number of bytes received compressed by the connection.
-
dwPortBytesXmited
-
Specifies the total number of bytes transmitted by the port.
-
dwPortBytesRcved
-
Specifies the total number of bytes received by the port.
-
dwPortFramesXmited
-
Specifies the total number of frames transmitted by the port.
-
dwPortFramesRcved
-
Specifies the total number of frames received by the port.
-
dwPortCrcErr
-
Specifies the total number of CRC errors on the port. CRC errors are caused by
the failure of a cyclic redundancy check. A CRC error indicates that one or
more characters in the data packet received were found garbled on arrival.
-
dwPortTimeoutErr
-
Specifies the total number of time-out errors on the port. Time-out errors
occur when an expected character is not received in time. When this occurs,
the software assumes that the data has been lost and requests that it be
resent.
-
dwPortAlignmentErr
-
Specifies the total number of alignment errors on the port. Alignment errors
occur when a character received is not the one expected. This usually happens
when a character is lost or when a time-out error occurs.
-
dwPortHardwareOverrunErr
-
Specifies the total number of hardware overrun errors on the port. These
errors indicate the number of times the sending computer has transmitted
characters faster than the receiving computer hardware can process them. If
this problem persists, reduce the BPS connection rate on the client.
-
dwPortFramingErr
-
Specifies the total number of framing errors on the port. A framing error
occurs when an asynchronous character is received with an invalid start or
stop bit.
-
dwPortBufferOverrunErr
-
Specifies the total number of buffer overrun errors on the port. A buffer
overrun error occurs when the sending computer is transmitting characters
faster than the receiving computer can accommodate them. If this problem
persists, reduce the BPS connection rate on the client.
-
dwPortBytesXmitedUncompressed
-
Specifies the total number of bytes transmitted uncompressed by the port. If
the port is part of a multilink connection, this member is not valid. Use the
compression statistics for the connection instead.
-
dwPortBytesRcvedUncompressed
-
Specifies the total number of bytes received uncompressed by the port. If the
port is part of a multilink connection, this member is not valid. Use the
compression statistics for the connection instead.
-
dwPortBytesXmitedCompressed
-
Specifies the total number of bytes transmitted compressed by the port. If the
port is part of a multilink connection, this member is not valid. Use the
compression statistics for the connection instead.
-
dwPortBytesRcvedCompressed
-
Specifies the total number of bytes received compressed by the port. If the
port is part of a multilink connection, this member is not valid. Use the
compression statistics for the connection instead.
