The information you are searching for is not present in the Fisheye DB.
We had a similar question in the past and as a workaround a query to provide last activity per user was provided.
You can find it at Get list of users sorted by last login or last activity date.
select cru_user_name, to_timestamp( max(cru_last_viewed)/1000), count(cru_user_name) from cru_recently_visited group by cru_user_name order by max(cru_last_viewed) desc;
Should give you roughly what you need.
It wont give you logins per-se, however will let you know which users recently viewed an 'entity' in FishEye/Crucible. An entity is: a repository, a project, a review or a user page.
You could also consult the cru_login_cookie table to get the last time a login cookie was created for any given user.
Hope this helps
The information about the last login can be retrieved by following the steps / running the query on the following article:
