Functions and Events: Network Indexes and Statistics

For each Network in Vehicle Spy there is an int variable. This variable is the number you use to reference a network. For example, the GenericMessage structure includes an iNetwork property. This indicates what network the message is from or will be transmitted to. All network indexes begin with the prefix NET_. Each network has statistics that you can access. You can access the statistics for a network with the GetStats function. You can reset the statistics with the ClearStats function.

Table 1: Statistics Available for a Network

Statistic Name	Data Type	Description
iCount	unsigned int	Count of messages on network.
iRate	unsigned int	Messages per second.
dPercentUse	double	Current bus utilization.
iMaxRate	unsigned int	Maximum messages per second.
dMaxPercentUse	double	Maximum bus utilization.
iErrorCount	unsigned int	Number of errors on a network.
iTxCount	unsigned int	Number of messages transmitted on a network.
iErrorRate	unsigned int	Errors per second.
iTxRate	unsigned int	Transmissions per second.
iTxBufferFill	unsigned int	Current network transmit buffer fill level. This level indicates how many bytes are in the transmit buffer. You can use this value to prevent buffer overflows.
iCANTxErrCount	unsigned int	Number of Transmit CAN errors.
iCANRxErrCount	unsigned int	Number of Receive CAN errors.

Figure 1: The network index variables allow you to define what network you are transmitting to or receiving from.

Figure 2: The GetStats and ClearStats API allows you to access the statistics for a network.
