Web log analysis on OpenBSD using GoAccess

GoAccess is an open source real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems or through your browser.


This only works with httpd, tested on OpenBSD 6.4

$ grep example.com /var/www/logs/access.log | cut -d' ' -f2- > stats.log  

Run GoAccess excluding local IP’s and specifing common style

$ goaccess -e --log-format=COMMON stats.log

Update HTML report every hour

Make a folder in your website for stats.html

$ doas mkdir /var/www/example.com/stats

Create script to be run by root’s crontab, then paste in the two commands below

$ doas vi /etc/hourly.local  
$ zgrep example.com /var/www/logs/access.log | cut -d' ' -f2- > stats.log  
$ /usr/local/bin/goaccess >/dev/null 2>&1 stats.log -o /var/www/htdocs/chevybeef.com/stats/stats.html --log-format=COMMON -e

Change to the root user

su -  

Edit root’s crontab with

# crontab -e  

Paste in the following line at the bottom

@hourly /bin/sh /etc/hourly.local  

Save and exit
Now, every hour on the hour the stats report HTML will be updated in:


Secure the stats folder with htpasswd

Create a user with these properties

stats:*:1002:1002:Stats Viewer:/home/stats:/sbin/nologin  
$ doas htpasswd /var/www/htpasswd stats  

Enter a strong password for the stats user and confirm
Change ownership of the htpasswd file

$ doas chown www:daemon /var/www/htpasswd  

Modify /etc/httpd.conf and include

location "/stats*" {  
authenticate with "/htpasswd"  

Reload the configuration

$ doas rcctl reload httpd
