Course activity reports
A course activity report, showing the number of views for each activity and resource (and any related blog entries), can be viewed by managers, teachers and non-editing teachers (and any other users with the capability report/outline:view) in Administration > Course administration > Reports > Activity report.
An activity report for the front page is available for administrators and managers in Administration > Front page settings>Reports > Activity report.
The length of time that the activity report covers is determined by the loglifetime setting in Administration > Site administration > Courses > Backups > General backup defaults.
An activity report is computed from the course's start date (in the course settings).
Individual activity reports
If activity reports are enabled for a course in the course settings, each course participant can access reports of their contributions, such as forum posts or assignment submissions, logs and a statistics report.
