To compare, I have made a "list" after best effort on what we are getting/not getting from each method.
A few observations (read Filtering in Confluence Access Logging):
- If You dont have the User Agent info and the site is public accessible - (Ro)Bots will give an incorrect result on pageviews; search bots for google, facebook etc are very active.
- Refer to Confluence SEO robots.txt for Managing search engines.
- You need to sort out agent of types: bot, spider, crawer, facebook from the results to get more correct results.
- Other monitoring/survaillance/measurement services can also have impact on the results.
