Active users and views in azure workbooks

Can someone briefly explain the differences between active users and page views in an azure workbook? I would like to get the stats of active users of a particular azure event, but the counts shown are not realistic for the provided scenario.

As per the attached image, there is only one active user, which has to be at least 3-4 and can go up to 15-16. The value displayed in Views is unrealistic though.

Your valuable inputs are highly appreciated. Thank you

if you edit the template/workbook and look at the queries you can see exactly what is going on there:

let start = startofday(ago({Metric}));
union customEvents, pageViews
| where timestamp >= start
| where name in ({Activities}) or '*' in ({Activities}) or ('%' in ({Activities}) and itemType == 'pageView') or ('#' in ({Activities}) and itemType == 'customEvent')
{OtherFilters}
| summarize Users = dcount(user_Id), Sessions = dcount(session_Id), Views = count()
| evaluate narrow()
| project Title = case(Column == 'Users', 'Active Users', Column == 'Sessions', 'Unique Sessions', 'Views'), Metric = Value, SubTitle = '━━'

views in this case, is a count of items in the tables; Views = count(), Users is dcount(user_Id) and Sessions = dcount(session_Id)

seeing just 1 user/session implies that there's nothing automatically generating "distinct" ids for those values, so the user_Id, session_Id fields are completely empty across all rows (the one unique id being undefined in both columns)

how user and session id values get populated is very specific to what application insights sdks you are using, and how you've configured them.
