[syslog-ng] How to turn logging into the .log files

Hi, Dukes. Thanks for your reply.

At this moment, I must to turn back to log into the .log files, at the 
same way of the beginning. This is urgent for now. (Below is my 
syslog-ng.conf file)

Next, my boss is asking me to test the Syslog plugin for Cacti.

Finally, if this solution doesn't solve our demand, I will consider to 
re-install and test the Logzilla.

---------------------
#
# Configuration file for syslog-ng under Debian
#
# attempts at reproducing default syslog behavior

# the standard syslog levels are (in descending order of priority):
# emerg alert crit err warning notice info debug
# the aliases "error", "panic", and "warn" are deprecated
# the "none" priority found in the original syslogd configuration is
# only used in internal messages created by syslogd


######
# options

options {
         # disable the chained hostname format in logs
         # (default is enabled)
         chain_hostnames(0);

         # the time to wait before a died connection is re-established
         # (default is 60)
         time_reopen(10);

         # the time to wait before an idle destination file is closed
         # (default is 60)
         time_reap(360);

         # the number of lines buffered before written to file
         # you might want to increase this if your disk isn't catching with
         # all the log messages you get or if you want less disk activity
         # (say on a laptop)
         # (default is 0)
         #sync(0);

         # the number of lines fitting in the output queue
         log_fifo_size(2048);

         # enable or disable directory creation for destination files
         create_dirs(yes);

         #dir_group(root);
         dir_perm(0755);

         # enable or disable DNS usage
         # syslog-ng blocks on DNS queries, so enabling DNS may lead to
         # a Denial of Service attack
         # (default is yes)
         use_dns(yes);

         # maximum length of message in bytes
         # this is only limited by the program listening on the /dev/log 
Unix
         # socket, glibc can handle arbitrary length log messages, but 
-- for
         # example -- syslogd accepts only 1024 bytes
         # (default is 2048)
         #log_msg_size(2048);

     #Disable statistic log messages.
     stats_freq(0);

     # Some program send log messages through a private implementation.
     # and sometimes that implementation is bad. If this happen syslog-ng
     # may recognise the program name as hostname. Whit this option
     # we tell the syslog-ng that if a hostname match this regexp than that
     # is not a real hostname.
