By looking on the "remote" system in the destination directory for files with "current" timestamps.

Can you see that recent redo log files get to the "other system"?

source:

ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=DS02.BD.NET LGWR ASYNC OPTIONAL NOREGISTER
VALID_FOR=(ALL_LOGFILES,PRIMARY_ROLE)' SCOPE=SPFILE;

ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=ENABLE SCOPE=SPFILE;
ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='send' SCOPE=SPFILE;

destination:

ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='LOCATION=/home/arc_dest/srl_dbs1 MANDATORY 
VALID_FOR=(STANDBY_LOGFILE,PRIMARY_ROLE)' SCOPE=SPFILE;

ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='receive' SCOPE=SPFILE;
ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=ENABLE SCOPE=SPFILE;

this is what I have done.

Verify the Physical Standby Database Is Performing Properly
On the standby database

SELECT SEQUENCE#, FIRST_TIME, NEXT_TIME
FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;

Force a log switch to archive the current online redo log file.
On the primary database

ALTER SYSTEM ARCHIVE LOG CURRENT;

Verify the new redo data was archived on the standby database.

SELECT SEQUENCE#, FIRST_TIME, NEXT_TIME
FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;

Verify new archived redo log files were applied.

SELECT SEQUENCE#,APPLIED FROM V$ARCHIVED_LOG
ORDER BY SEQUENCE#;
