IONetworkStats.h

Include:

Path <IOKit/network/IONetworkStats.h>

Overview

This header provides you with various structures that provide statistics about network usage that you may find useful. Included are general and output queue statistics.



Typedefs


IONetworkStats


typedef struct { 
    UInt32 inputPackets; 
    UInt32 inputErrors; 
    UInt32 outputPackets; 
    UInt32 outputErrors; 
    UInt32 collisions; 
} IONetworkStats;  
Fields
inputPackets

count input packets.

inputErrors

count input errors.

outputPackets

count output packets.

outputErrors

count output errors.

collisions

count collisions on CDMA networks.

Discussion

Generic network statistics structure.


IOOutputQueueStats


typedef struct { 
    UInt32 capacity; 
    UInt32 size; 
    UInt32 peakSize; 
    UInt32 dropCount; 
    UInt32 outputCount; 
    UInt32 retryCount; 
    UInt32 stallCount; 
    UInt32 reserved[4]; 
} IOOutputQueueStats;  
Fields
