MIBICMPSTATS (Windows Embedded CE 6.0)

1/6/2010

This structure contains statistics for either incoming or outgoing Internet Control Message Protocol (ICMP) messages on a particular computer.

Syntax

typedef struct _MIBICMPSTATS {
  DWORD dwMsgs; 
  DWORD dwErrors; 
  DWORD dwDestUnreachs; 
  DWORD dwTimeExcds; 
  DWORD dwParmProbs; 
  DWORD dwSrcQuenchs; 
  DWORD dwRedirects; 
  DWORD dwEchos; 
  DWORD dwEchoReps; 
  DWORD dwTimestamps; 
  DWORD dwTimestampReps; 
  DWORD dwAddrMasks; 
  DWORD dwAddrMaskReps; 
} MIBICMPSTATS;

Members

• dwMsgs
  The number of messages received or sent.

• dwErrors
  The number of errors received or sent.

• dwDestUnreachs
  The number of destination-unreachable messages received or sent. A destination-unreachable message is sent to the originating computer when a datagram fails to reach its intended destination.

• dwTimeExcds
  The number of time-to-live (TTL) exceeded messages received or sent. A time-to-live exceeded message is sent to the originating computer when a datagram is discarded because the number of routers it has passed through exceeds its time-to-live value.

• dwParmProbs
  The number of parameter problem messages received or sent. A parameter problem message is sent to the originating computer when a router or host detects an error in a datagram's IP header.

• dwSrcQuenchs
  The number of source quench messages received or sent. A source quench request is sent to a computer to request that it reduce its rate of packet transmission.

• dwRedirects
  The number of redirect messages received or sent. A redirect message is sent to the originating computer when a better route is discovered for a datagram sent by that computer.

• dwEchos
  The number of echo requests received or sent. An echo request causes the receiving computer to send an echo reply message back to the originating computer.

• dwEchoReps
  The number of echo replies received or sent. A computer sends an echo reply in response to receiving an echo request message.

• dwTimestamps
  The number of time-stamp requests received or sent. A time-stamp request causes the receiving computer to send a time-stamp reply back to the originating computer.

• dwTimestampReps
  The number of time-stamp replies received or sent. A computer sends a time-stamp reply in response to receiving a time-stamp request. Routers can use time-stamp requests and replies to measure the transmission speed of datagrams on a network.

• dwAddrMasks
  The number of address mask requests received or sent. A computer sends an address mask request to determine the number of bits in the subnet mask for its local subnet.

• dwAddrMaskReps
  The number of address mask responses received or sent. A computer sends an address mask response in response to an address mask request.

Remarks

Two MIBICMPSTATS structures are required to hold all the ICMP statistics for a given computer. One structure contains the statistics for incoming ICMP messages. The other contains the statistics for outgoing ICMP messages. For this reason, the MIBICMPINFO structure contains two MIBICMPSTATS structures.
