Log file analysis

Sample of log file for this site using analog.exe

Each line from the server log shows the originating IP address, the date and time, the page called and, where available, the link origin.

Log file analysis results

I use a program called analog.exe to analyse the log files. I use an ancient, 20 years old, version 5.91beta1.  You can get the latest version here.

The first thing to do is add up all the logfiles for the month, or whatever. This puts all the inout data into ine giant log file. You can do this at the DOS prompt with a command like:

copy acc* big.txt

That copies all the apache files like access-logfile.2023.03.07  access-logfile.2023.03.08 etc into one big text file. e.g big.txt

You then need to edit the config file for analog.exe, analog.cfg,  like so:

HOSTNAME "www.satsig.net"
LOGFILE C:\Users\***\***\***\var\log\httpd\ssl-www.satsig.net\mar2023\big.txt
OUTFILE C:\Users\***\***\***\var\log\httpd\ssl-www.satsig.net\mar2023\traffic-1-17mar2023.htm

The result is an output html file like traffic-1-17mar2023.htm which may be displayed using Chrome, opened with Control O

This file shows how many times each page has been viewed, has failed to serve, has been referred etc.
