Look up detail module in freeradius. It logs the whole Accounting-Request
to a text file, but you can filter out what you don't want. Or sql
module to log into the database. Again, queries are configurable - log
only what you want.

It works as reliably as your network. If some requests don't make it to
the radius server - no records are created.
