Identify what auditing is on

Suspect too much auditing is on on a database? This script will show you what auditing is on:

set pages 9999
select * from DBA_STMT_AUDIT_OPTS ;
select * from DBA_PRIV_AUDIT_OPTS ;
set termout off lines 192
spool 1.tmp
select * from DBA_OBJ_AUDIT_OPTS ;
spool off
set termout on lines 80
host egrep '(S/|A/|/S|/A)' 1.tmp

Note that the unix command egrep is used to filter the dba_obj_audit_opts rows of interest.
