# fl Analytics for `HTTP` logs in Forwarded Log Format ## Install On a Linux or BSD machine, in a terminal, run: mkdir -p ~/src cd ~/src wget -qO - https://adi.onl/fl/fl@1.0.0.tgz | tar -xzvf - cd fl make install PREFIX=$HOME ## Uninstall cd ~/src/fl make uninstall PREFIX=$HOME ## Usage The package provides 8 scripts `flp`, `flu`, `flv`, `flr` and `flvp`, `flvu` , `flvv` and `flvr`. The **fl** prefix stands for _Forwarded Log_ and the suffixes stand for _**p**ages_, _**u**nique_, _**v**iews_ and _**r**eferrers_. The middle **v** in the second set stands for _virtual host_. The second set of 4 scripts is for the Forwarded Log with virtual hosts format. It's identical to the normal Forwarded Log except the name of the virtual host is prepended to each line. Use the appropriate script for the statistic and for the log format: ### Pages $ flp /var/www/access.log /docs.html 641 / 3227 Use `sort -nrk 2` to sort on second column: $ clp /var/www/access.log | sort -nrk 2 / 3227 /docs.html 641 ### Uniques and Visits Uniques and visits scripts output the actual unique and visit requests by default. Use `wc -l` to count: $ flu /var/www/access.log | wc -l 2000 ### Referrers $ flr /var/www/access.log none 865 https://example.com 1222 Use `sort -nrk 2` to sort on second column: $ flr /var/www/access.log | sort -nrk 2 https://example.com 1222 none 865 We recommend using [cblfb](http://adi.onl/cblfb.html) for filtering bots. $ flr /var/www/access.log | cblfb none 821 https://example.com 1212 Also, it's a good idea to enable log rotation. The scripts operate on `GET` requests to paths with no extension or ending in `.html` that returned a 200 HTTP response status code. https://example.com/docs https://example.com/docs/ https://examples.com/docs.html
