Can I use Insights or native reporting to report on Help Center article creation, article created versus published dates, or articles per topic?
No, it is not yet possible to pull Help Center data into Insights. Furthermore, native reporting is currently limited to viewing top content, searches, and agents (see Using the Reporting Overview).
For customers on a Team plan and up, this data can be extrapolated with Google Analytics. This integration allows you to report on your Help Center by views, searches, and click events. For more information on setting this up, see Enabling Google Analytics for your Help Center.
