I have mysql binlogs for replication through GTID.

I'm trying to show executed update/insert statements like this:

mysqlbinlog --base64-output=DECODE-ROWS mysql-bin.000024

But all I see is something like this, no traces of update or insert stmt:

SET TIMESTAMP=1431681617/*!*/;
BEGIN
/*!*/;
# at 746987321
# at 746987392

#150515 11:20:17 server id 1  end_log_pos 746987515 CRC32 0xeb874754    Xid = 997501767
COMMIT/*!*/;
# at 746987515
#150515 11:20:22 server id 1  end_log_pos 746987563 CRC32 0xc5ece64a    GTID [commit=yes]
SET @@SESSION.GTID_NEXT= 'a4ade293-c63a-11e4-94cf-005056944a56:2059057'/*!*/;

I'm not sure about format/configuration of GTID replication and where to look for it...
