This optional parameter allows you to change the way Radiator formats accounting log JSON output by mapping RADIUS attributes to JSON fields. Multi-valued RADIUS attributes are added as a JSON array. When this parameter is not defined, all RADIUS attributes are encoded. The general format is:

AcctLogOutputDef jsonattributename[,radiusattributename]

If radiusattributename is omitted, jsonattributename is used as RADIUS attribute name. Special variables, such as %n, can also be used in radiusattributename. Note that in this case % must be the first character in the radiusattributename.

For extensive customisation of JSON and other formats, see LogFormatHook and Radius::LogFormat module. For a configuration sample, see goodies/logformat.cfg file in the Radiator distribution.
