Just installed Simple Login Log, great plugin!
Ran into problem however… we're installing it on a WP multisite (with many domain-based sub-blogs). Some of these blogs are also domain-mapped btw, however that should not make a difference.
The problem is:
1.) Logins to via the top-level site (mysite.com/wp-login.php) are logged to this table: wp_simple_login_log
2.) However, logins to sub-sites in the same wordpress multisite install (i.e. bobsblog.mysite.com/wp-login.php), are logged into separately created tables for each sub-blog. i.e. for blog ID 92, they're logged to this table: wp_92_simple_login_log
This is problematic as a network administrator because I can't see ALL of the logins in one place.
It is also problematic because a new table is getting created for each network blog - this is 1000's of unnecessary tables!
Since users are created at the top level in WordPress, it makes sense that all of the logging would be stored at the top network level as well.
