Information that is logged by the Web API
Logs are written to an “API” group of log files that is in the standard log file location, that is:
C:\Program Files\IBM\SPSS\DataCollection\7\Interviewer Server Administration\Logs
To control what information is recorded
To control what information is recorded in the log files, use the values that are in the registry at HKEY_LOCAL_MACHINE\SOFTWARE\SPSS\WebApi\Log.
The values for the “API” log group are the same as all other log registry values. For example, to enable trace level logging, set the Filter registry value to 0.
After changing any log settings, restart the Web API by using the iisreset command or an app pool recycle.
To control what information is recorded at the trace level
To control what information is recorded at the trace level, use the DPM properties that are under \Site\Properties\WebApi\ComponentConfiguration\Common.
