Collected Statistics
BVCI/CI based statistics
The Sga-GPRS system collects messages from the network and creates many statistics from them written into *.GpS files on the server machine
in the Sga8NStD.ini/[Advanced]/sStat1FilesPath path (D:\Stat1Files) .
These statistics are resoluted by BVCI (BSSGP Virtual Connection Identifier) and CI (Cell Indentifier) values, grouped for Statistical groups.
(Groups can be defined by GPRSmonitor.ini/[StatGroupX] sections.)
The following statistical counters appear in the statistics output, after the Date/Time, LinkGroup, BVCI, CI fields.
The name of these statistics are defined in the [Stat1 Counter Names] section of Sga8NStD.ini
and their parameters (if needed) are set in GPRSmonitor.ini/[Stat] section.
