Auditing Universe Questions

Hello,

I am needing assistance with the auditing universe.  Here are my questions:

1. How many "ways" are there for the "login" event?  I am trying to figure out what the universe considers as a "login" event.  Is that just when someone logs in to BO?  What about scheduled reports?  Is it considering an automatically scheduled report that runs a "login"?  What about reports that are accessed on SharePoint sites?  Is it considered a "login" when someone opens an OpenDocument report on a S.P. site?
2. If all of these are considered login events, how can I filter/categorize them within the report?  We are trying to show a business case for the number of logins in each of the categories I've listed above.

If anyone has any suggestions, I would be extremely greatful.

Thank you,

Aaron
