User Session Consuming



I'm writing about "When does a user session end?" listed in the following site,

Recently, Has conditions changed?

In the past, I remember that it was the following condition.

Past: Following 6 hours of browser/tab activity.

Now: Following 1 hour of browser/tab activity.

When did you see 6 hours? From Time I remember there always was an hour (the same was in Appmon).

In Sep 2018, It was definitely "6 hours"

Because I made materials for my colleagues to explain the condition of user session.

And, although it is another question, there are also people who write "6 hours" as well.

So maybe somebody from dynatrace will tell something about it. I was always remembering 60 minutes not 6 hours but maybe there was some change or mistake in documentation.

You have to differentiate between two aspects

  • user session duration
  • DEM units calculation

User session ends

  • after 30 minutes of user inactivity
  • after closing of browser tab/window
  • after reaching 200 user actions or 6 hours (new session is automatically initiated)
  • explicitely after calling RUM JS dtrum.endSession() in the page

However, DEM units calculation is slightly different. Normally each session should equal 0.25 DEM. But there are some differences in counting sessions into DEM units:

  • Beginning of each hour within a session is counted as a new session (albeit it is still technically the same session within the product)
  • Each visited application is counted separately (if a user visits 3 applications within one session, it will be counted for each application separately).
  • Sessions with single action are not counted.

Thanks for your kindly reply.

As you said, I confused user session duration and DEM units calculating.
