Configure System log (syslog) Server

Raspbian (debian) server can be used as a machine recording log from external devices such as router.
Install syslog-ng and related mods as well.

  sudo apt-get install syslog-ng 

After finishing installation, edit /etc/syslog-ng/syslog-ng.conf.

  source s_net { udp(ip( port(514)); };  
  destination d_router { file(/var/log/router.log”); }; 
  log { source(s_net); destination(d_router); }; 

source s_net defines the source where records are from will be bind to all interfaces.
destination set your arbitrary name like d_router and set the path of log file.
log tells what source to use and what destination to take. If you have 'filter' option to utilize for more refined log results.
Create log file.

  sudo touch /var/log/router.log 

And restart syslog-ng service

  sudo systemctl stop syslog-ng.service 
  sudo systemctl start syslog-ng.service 

For sensitive reason, you would better to stop & start service instead of restart.
Check size of log file is getting bigger and contents of log file.

For archiving and compressing log files, edit /etc/logrotate.d/

        rotate 4
                invoke-rc.d syslog-ng reload > /dev/null

Delete unnecessary files regularly

sudo crontab -e Add command line to find & delete. e.g.) Delete all .nfo file in target directory and its sub-directories at 30 minutes past every 6 hours.

  30 */6 * * * /usr/bin/find /..((your path)).../ -name '*.nfo' -exec rm -f {} \;

Delete empty directory at 30 minutes past every 12 hours

  30 */12 * * * /usr/bin/find /..((your path)).../ -type d -empty -delete

Delete all files except for desired file types

 find . -type f ! -name '*.mkv' -delete
