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

capacity: queue capacity.
size: current size of the queue.
peakSize: peak size of the queue.
dropCount: number of packets dropped.
outputCount: number of output packets.
retryCount: number of retries.
stallCount: number of queue stalls.

Discussion

Statistics recorded by IOOutputQueue objects.
