The Portal Activity Report is one of the best loved, and often hated, features of the portal. Almost every customer wants to know, at one point or another, who is using the portal and what users are looking at. But there is often a lot of confusion over the feature, generally because they “know” that users have entered the portal but do not see any statistics, or they see statistics in one report that seem to contradict another report. From time to time, I will write a few words about the Portal Activity Report to make it clearer how it works. This blog focuses on the most basic report, showing how many users have logged into the report. Many customers believe this report shows how many logons were performed. Wrong. The report shows how many unique IDs logged on to the portal. So if the administrator logged on 235,333 times yesterday, the report would still show 1 logon. This has important implications in comparing reports from different time periods. For example, the following is a daily report of the number of users who logged in during December: The red lines show the days during work week 51 (starting Dec. 19) and work week 52 (starting Dec. 26). The report shows a total of 3 authenticated users in WW51 and 9 in WW52. But now look at the weekly report: This report shows 1 user in WW51 and 4 in WW52. The difference is because the reports show unique IDs that logged in, not actual logons. So the administrator user may have logged in each day, and appears as a separate statistic in the daily report, the user only appears once in the weekly report. Also note, that the work week begins on a Monday.
