How to override Devise Session Features

[Toby Joy]

I am a beginner at Ruby on Rails, I need to track the user activities in
the application, and to keep a record of each session activities. The
required fields to store in the database are:
1) all login attempts(valid/invalid)
2) sign-in time
3) sign out time
4) whether it is user signout/system time out
and also any useful information to track a user activity.

The session timeout is working as below:

In devise.rb, I added :
config.timeout_in = 5.minutes

and in user.rb, I added:
devise :timeoutable

After session time out in the application, I need to store the user
activity as 'session expired' in the database.

If it is a normal 'sign out' then also need to store that info into
table.

After tons of search, i found that sign_in and sign_out features can be
controlled through SessionController. But didn't get any document on how
to override devise timeoutable feature.

What I need to do. Please advise.

Thanks in Advance
