Session Aggregator

Description

This module will capture and aggregate user session data in order to provide the following:

• Elapsed Time: total time a user has spent on the site
• Session Count: total number of unique sessions for a user
• Date: A time stamp since the data started being collected

Dependencies

• Automated Logout (6.x-4.x)
• Session Limit
• Views (6.x-3.x-dev) - not required but its the only way to see the data

These modules are a requirement because they help to keep clean session data. Its highly recommended to limit the sessions to 1 per user.

How it works

When a user logs in, the session count field is incremented for a user and their session id and creation time are saved for later use. When the user is logged out, the session's time span is added to the user's elapsed time.

When a session collision is detected by the Session Limit module the time span of the session being closed is added to the user's elapsed time if the time span of the closed session is less than the time limit specified by the Automated Logout module. But if the time span of the closed session is greater than time limit, meaning a hung session has been detected, the time limit specified by the Automated Logout module is added to the user's elapsed time.

Its important to remember that the elapsed time field is only updated during
a successfull logout or when a session collision is detected. So the elapsed
time is not up to date for currently logged in users.
