Questions on QMC's Engine Health page.

[stascher]

Hello,

With regards to the QMC's Engine Health page, I have some questions.

1) What is the difference between Active users and Total users? Specifically, what constitutes "active" vs "inactive" users? 

2) I assume the answer to the above applies to Active versus Total sessions also? 

3) What is the difference between an Active App and an In-memory app? I assume that Active Apps are being accessed by Active users? What makes an app "in memory" but not active? Note, we don't use pre-loading. Also, how long will a "in memory but not active" app stay in memory?

Thank you.

Hi @stascher ,

1) An active user is one who is currently performing an action on an app. Total users are the total number of distinct users within the current engine sessions. The moment a user stops interacting with a Qlik app, it becomes an inactive user and counts against the "Total Users" count.

2) Correct. The main difference is that a session is a user on an app. So a user in two apps will show up as two sessions.

3) In-memory apps are the apps that remain in memory, after the last user session that used the app has ended. The amount of time it stays in memory is configured on /qmc/engines/ under "App cache time (seconds)".

If you have any more questions, let me know! Love to help.
