An event, with reference to Event Logging, is any significant occurrence in the system or in a program that requires an entry to be added to a log. Keeping record of such events is Event Logging.
Content Versioning System is used for tracking changes in files and coordinating work on those files among people.

User’s login to Drupal
Drupal
Event Logs
Drupal uses PHP to run user code

PHP
Web Server
PHP sends user code via web server’s like apache, IIS, etc
Accesses user data sends back to user
Real time logs
Database

4. ABOUT THE PROJECT
In this project, we have tried to enhance the functionality of the existing Event Log module in Drupal 7
Also, we have tried to facilitate the development of Recommendation System by Collaborating Communities Project group.
Besides, we have tried to implement the graphical analysis of event log data.
The modules developed are compatible with any Drupal 7 system with PHP7 installed.

5. FEATURES Interface For Collaborating Communities
Log Data Visualizations
Enhancement Of Event Log Module

6. INTERFACE FOR COLLABORATING COMMUNITIES:
Show the top 10 viewed articles
Show the top 10 viewed articles along with the corresponding tags by a particular user
Provide the necessary data for development of recommendation system by collaborating communities.

7. Articles and corresponding tags for a particular user:

8. LOG DATA VISUALIZATIONS
OPERATION ANALYSIS:
To represent the total count of each operation in the database
To represent the monthly triggering of each operation
Weigh each page according to page rank to create a node with its diameter and connect that node with other nodes(pages) to which it is linked.
USER ANALYSIS:
To display the top N(input) active users
To visualize the operations performed by a particular user

9. Line Graph:

10. Force Directed Graph:

11. ENHANCEMENT OF EVENT LOG MODULE
Clear the logs
Notify illegal access to authorised user
Log data to a file instead of database
Backup Event Log database content
Store logs on the Cloud instantaneously

12. Real time logs:

13. CHALLENGES
Identifying the appropriate module for development amongst many, namely – syslog, watchdog, event log, etc.
Making development compatible with the existing system.
Resolving storage path and permission issues of files in drupal core.

14. KNOWLEDGE ACQUIRED Construction of modules in Drupal 7
Data visualization using D3
