Appendix D.1. Driver Stats
The driver reports statistics according to the FieldServer standards. The following notes describe
some aspects of standard statistic reporting which are peculiar to this driver.
• All error responses from the Carrier DataPort device are recorded as PROTOCOL ERRORS,
In addition to the standard FieldServer communication statistics described above and in the
FieldServer Instruction Manual, this driver can also expose some driver statistics by writing data to a
Data Array. A special Map Descriptor is required. The driver recognizes the Map Descriptor by its
name which must be "CarrierDP-stats”.
The following example shows how this special Map Descriptor can be configured. You can copy this
section of text directly into your CSV file.
Nodes
Node_Name , Station, Protocol
CarrDP_stats , 1 , CarrierDP
Data_Arrays
Data_Array_Name , Data_Format, Data_Array_Length
DA_CARRIERDP_STATS , UINT32 , 2000
Map_Descriptors
Map_Descriptor_Name, Data_Array_Name , Data_Array_Offset, Function, Node_Name , Length,
CarrierDP-Stats , DA_CARRIERDP_STATS, 0 , passive , CarrDP_stats, 500
When the driver sees this Map Descriptor it uses the Data Array DA_CARRIER_STATS (in this
example) to store driver specific statistics. Only one of these Map Descriptors may be specified per
FieldServer.
The driver stores the following data. The location in the Data Array is obtained by multiplying the
port number by 50 and then using the location offset indicated in the table below.
