Web Server Log Parser

Problem Statement

The test is as follows:

1. ruby_app

Write a ruby script that: a. Receives a log as argument (webserver.log is provided)

e.g.: ./parser.rb webserver.log

b. Returns the following:

list of webpages with most page views ordered from most pages views to less page views e.g.:

/home 90 visits /index 80 visits etc...

list of webpages with most unique page views also ordered e.g.:

/about/2 8 unique views /index 5 unique views etc...

Example

To install all dependencies, compile and run tests:

$ bin/setup

To run the code so it accepts input from a file:

$ bin/parser data/webserver.log

Output (to STDOUT):

List of webpages with most page views ordered
Webpage(Endpoint)      Count
/about/2                         90 visits
/contact                         89 visits
/index                           82 visits
/about                           81 visits
/help_page/1                     80 visits
/home                            78 visits

List of webpages with most unique page views also ordered
Webpage(Endpoint)      Count
/help_page/1                     23 unique views
/contact                         23 unique views
/index                           23 unique views
/home                            23 unique views
/about/2                         22 unique views
/about                           21 unique views
