I'm trying to figure out why the results in a document's Popularity trends usage report the data is not in line with actual use.
Usage and Health Data Collection is configured, WSS_ADMIN_WPG and WSS_WPG can access log folder and the data is being stored into usage database properly by the timer jobs. The report does show usage for some days and some not. When reading the data from usage database directly I can confirm the reads are there but they've not been fully included into the report.
For example for 15th the popularity trend report shows 4 reads by 3 unique users but when reading from RequestUsage in database there are 9 reads by 3 users.
DateTime UserLogin Duration 15.7.2016 8:17 visitor 130 15.7.2016 8:17 visitor 17 15.7.2016 8:22 visitor 23 15.7.2016 8:27 contrib 69 15.7.2016 8:28 contrib 15 15.7.2016 9:04 owner 71 15.7.2016 9:05 owner 14 15.7.2016 9:47 contrib 15 15.7.2016 12:05 visitor 21
Is there some minimum duration which the document needs to be open for it to register in the report? Or is there some amount of time required between reads from same user before they count as different reads? I can understand that reads within few minutes would be counted as one but it seems the gap is more like some hours.
Tailtrimming for views was originally 2 but I've now dropped it to 0 so that all activity should register.
