MIBICMPSTATS structure (ipmib.h)

The MIBICMPSTATS 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, *PMIBICMPSTATS;

Members

dwMsgs

Type: DWORD

The number of messages received or sent.

dwErrors

Type: DWORD

The number of errors received or sent.

dwDestUnreachs

Type: DWORD

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

Type: DWORD

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

Type: DWORD

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

Type: DWORD

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

Type: DWORD

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

Type: DWORD

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

Type: DWORD

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

dwTimestamps

Type: DWORD

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

Type: DWORD

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

Type: DWORD

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

Type: DWORD

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 MIBICMPSTATS 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.

On the Microsoft Windows Software Development Kit (SDK) released for Windows Vista and later, the organization of header files has changed and the MIBICMPSTATS structure is defined in the Ipmib.h header file not in the Iprtrmib.h header file. Note that the Ipmib.h header file is automatically included in Iprtrmib.h which is automatically included in the Iphlpapi.h header file. The Ipmib.h and Iprtrmib.h header files should never be used directly.
