I dont think you can. But you can spot tables and indexes that arent logged

select table_name from dba_tables
where logging !='YES'
union all
select table_name from dba_indexes
where logging !='YES'

you can change that with ALTER TABLE ... LOGGING etc.

Then you have to spot the statements
that contains hints that generate DIRECT (no logged) operations like APPEND,TRUNCATE thru v$sqltext view

You can take a look to v$datafile dynamic view it has 2 unrecoverable_* fields that would help you spotting if there are other DIRECT operations performed from applications/tools

Take in account that a NOLOGGED DML is much faster than a logged one.
