Background: We have legacy Windows applications deployed on MS Server platforms. Over 60 of them, each attached to individual customer DB. We have also have a new cloud-based solution and the aim is to migrate customers across.

Done: To identify area of the original program most used (and areas not used by anyone for years!) I’ve added events triggers, sending page_view, session_start and a few custom events. Can see these events coming into GA4 in the real time viewer.

But but but: Don’t see how to take this further. I see after a day or two, some graphs saying so many events have arrived but nothing ‘insightful’! How do I look to extract meaningful revelations. (For example, list of pages by name in most used order. Total time spent by all customers per page. Etc.)

What I’m I missing? Any recommendations for books or courses.
Many thanks
