Simple Logger

This simple app receives a log file in input and returns the list of web pages with most page views ordered. It also returns the list of web pages ordered by the number of unique IPs that have visited each specific page.

Usage

If you have a Ruby interpreter installed, you can just type:

ruby main.rb webserver.log

Or if you prefer to use bundler:

bundle install
bundle exec ruby main.rb webserver.log

Supported file format

Currently, the Simple Logger can parse only text files with the following syntax:

$website_path $pseudo_ip_address

$website_path format: {[a-z0-9/_]{1,}}
$pseudo_ip_address format: {[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}}

The idea behind

• LogLine: it is responsible for preserve the original line of text, and after validations respond to ip and url messages.
• Link: it stores a link and keeps track of the total numbers of views and the number of unique IPs. Its add_ip method is responsible for increment the visit counter and collects unique IPs.
• Links: it receives an array of elements and stores them into an enumerable collection of entities (likely Link(s)) and provides some methods to order them.
• LogParser: it acts as a container, it is responsible for file-related operations and it delegates received messages to the others components.
• Formatter it is a stand-alone entity that format the received arguments according to some options.
