Online Users library Addin

Because in CI 3 it's set_userdata()

Thank you InsiteFX,

set_data is a function in the library class 'Onlineusers'.

The problem in changing online guest to member, it requires 15 min to update him.

I have two solutions:
1. Reducing the time out to a small number like 15 instead of 900 in line:
$timeout = $now - 900;

Is this bad a take more resources?

2. Loading online library only for logged in users; so there will be no guests. But I will not know online guests and bots.

Does any one know another library depends on database not file and store online and today users?
