On course layer the reports for external tools seems to be missing.
1. You need an course with an lti activity an recent activity in the module.
2a. Go to Navigation current course/course_name/reports/Activity report
3a. You will find no access data to the lti activity at all
2b. Go to Navigation current course/course_name/reports/Course participation
3b. Choose an lti activity which was recently used and click Go
4b. Getting an error message:
Module lti is missing the code needed to perform this function
When i take a look in the log, i see the actions on the lti modules. So i think the report itself is missing or does not find the log entries. Strange behavior: when you filter the log report by the lti activity the actions of the lti activity disappear too.
