Hi,
in my opinion, there is no direct method but we could possibly do one by
instrumenting some code. You could store the value for "bytes received/sent
via SQL*Net from/to dblink" from v$SESSTAT and the access the object and
then check the value again?. I have not tried this myself but should work.
do let me know if this works or otherwise
best regards
