I have made that changes and restarted syslog services even though its not working///
Now its like this

options {
               long_hostnames(off);
               sync(0);
               perm(0640);
               stats(3600);
               keep_hostname(yes);
};
source s_external {
        udp(port(514));
        #udp(ip("192.168.114.129") port(514));
        #udp(ip("0.0.0.0") port(514));
};  # Specific
source s_stunnel {
        tcp(ip("127.0.0.1")
        port(514)
        max-connections(1));
       };
destination d_external { file("/data/extract/syslogs/$HOST_syslog.log" \
    owner(cubot) group(users) perm(0600) dir_perm(0700) create_dirs(yes)
    template("$DATE $FULLHOST $PROGRAM $TAG [$FACILITY.$LEVEL] $MESSAGE \n") );
        };

destination d_stunnel{ file("/data/extract/syslogs/$HOST/$HOST_syslog.log" \
    owner(cubot) group(users) perm(0600) dir_perm(0700) create_dirs(yes)
    template("$DATE $FULLHOST $PROGRAM $TAG [$FACILITY.$LEVEL] $MESSAGE \n") );
        };

log { source(s_external); destination(d_external); };
log { source(s_stunnel); destination(d_stunnel); };
