I'm trying to track SharePoint adoption in our environment. Not looking for anything as sophisticated as "how extensively are our users accessing SharePoint" - just "how many distinct users are logging into SharePoint each month. All users are logging in via Windows Authentication.
Any ideas?
If you are looking for something simple, I think OOTB Usage reporting could do for you. Click here to learn about configuration, and check this blog post for a detailed explanation for each report available.
