The name of a file used to log failed Accounting-Request
messages in the standard radius accounting log format. If the SQL database
insert fails, the accounting message will be logged to the named file. For
more information about file format, see Section 9.5. Accounting log file. If no
AcctFailedLogFileName is defined, failed accounting messages will not be
logged. The default is no logging. The file name can include special
formatting characters as described in Section 3.3. Special formatters, which means that,
for example, using the %c specifier, you can maintain separate accounting
log files for each Client. The AcctFailedLogFileName file is always opened
written and closed for each failed insertion, so you can safely rotate it
at any time.
The user name that is recorded in the log file is the
rewritten user name when RewriteUsername is enabled.
Note
You can
change the logging format with AcctLogFileFormat.
Note
You may want
to make the filename depend on the date, so you get one missed accounting
file per day.
