I'm developing a kind of standard web-application, to be hosted internally on few customer's servers (not a public service, startup or anything like that). A kind of CMS, e-learning platform or something close to that. Because this is an internal project, customer had given me quite a large decision field and did not specified problem in question.

My developed web-application is planned to have few admins and only one superuser per each installation. In this case, should application logs be available to admin-level users or strictly prohibited to be viewed by superuser only?
