drupal-logger is a project undertaken by fundamental research group at IIT,Bombay which focuses on advancing the event log module in drupal which was developed earlier by Cipix Internet. This module logs specific events. The events are saved in the database and can be viewed on the page admin/reports/events. Furthermore, a views integration is provided in which you can relate for instance a node to its events. You could use this to display the total number of views, or the number of times that the node has been modified and by which users.

Currently, the following events are supported:

• User authentication (login/logout/request password)
• Node operations (CRUD)
• User operations (CRUD)
• Menu operations (custom menu's and menu items CUD operations)
• Taxonomy operations (vocabulary and term CUD operations)

drupal-logger empowers the users to more advanced features based on the core event log module. Apart from the above features, four new features have been added: Namely,

• Clear log messages button
• Ability to log to a file instead of a database.
• Backup event_log database content.
• Notify Illegal access to authorized user.
• Log data to Cloud (Experimental)

Since data visualization is imperative and indispensable to business and data analytics, drupal-logger comes with three pellucid visualizations. Namely,

• Log Data Visualization
• Log data Visualization User
