These tags are very similar:
Should some of them be merged?
In my opinion, these tags shouldn't be merged because they have different meanings.
Tracking and reporting are just a part of analytics; there is also the analyzing part in analytics. I think analytics is more general than tracking. In general, tracking is for a specific action (a button for instance), analytics is the analysis of traffic for an entire site.
Otherwise, tracking and logging have also different meanings for me. You can log actions of a user with never look at into the file to analyze the result.
"tracking", "analytics", and "reporting" should be merged. They mean the same thing. I'm also in favor of including "statistics" in the merge. It could mean something different, but in the context of a site about being a webmaster, it is talking about website tracking. The questions tagged with it could fit in the same bucket just fine. The canonical tag should be analytics because it is the most popular.
Logging is a different concept and should be left separate.
