## Set up Log Analysis Reports

Analog is a program with processes webserver access logs, performs DNS lookup, and outputs HTML reports. Analog should already be installed. A modified configuration file is included in the OpenACS tarball.

1.     [root src]# su - $OPENACS_SERVICE_NAME
       [$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ cd /var/lib/aolserver/$OPENACS_SERVICE_NAME
       [$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ mkdir www/log
       [$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ cp -r /usr/share/analog-5.32/images www/log/
       [$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$
       su - $OPENACS_SERVICE_NAME
       cd /var/lib/aolserver/$OPENACS_SERVICE_NAME
       cp /var/lib/aolserver/$OPENACS_SERVICE_NAME/packages/acs-core-docs/www/files/analog.cfg.txt etc/analog.cfg
       mkdir www/log
       cp -r /usr/share/analog-5.32/images www/log/

   Edit `/var/lib/aolserver/$OPENACS_SERVICE_NAME/etc/analog.cfg` and change the variable in `HOSTNAME "[my organisation]"` to reflect your website title. If you don't want the traffic log to be publicly visible, change `OUTFILE /var/lib/aolserver/$OPENACS_SERVICE_NAME/www/log/traffic.html` to use a private directory. You'll also need to edit all instances of service0 to your $OPENACS_SERVICE_NAME.

2. Run it.

       [$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ /usr/share/analog-5.32/analog -G -g/var/lib/aolserver/$OPENACS_SERVICE_NAME/etc/analog.cfg
       /usr/share/analog-5.32/analog: analog version 5.32/Unix
       /usr/share/analog-5.32/analog: Warning F: Failed to open DNS input file
         /home/$OPENACS_SERVICE_NAME/dnscache: ignoring it
         (For help on all errors and warnings, see docs/errors.html)
       /usr/share/analog-5.32/analog: Warning R: Turning off empty Search Word Report
       [$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$

   Verify that it works by browing to `http://yourserver.test:8000/log/traffic.html`

3. Automate this by creating a file in `/etc/cron.daily`.

       [$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ exit
       logout

       [root root]# emacs /etc/cron.daily/analog

   Put this into the file:

       #!/bin/sh

       /usr/share/analog-5.32/analog -G -g/var/lib/aolserver/$OPENACS_SERVICE_NAME/etc/analog.cfg

       [root root]# chmod 755 /etc/cron.daily/analog

   Test it by running the script.

       [root root]# sh /etc/cron.daily/analog

   Browse to `http://yourserver.test/log/traffic.html`
