the QlikView Governance Dashboard is a fantastic free tool available for download that will give you all the information you need.
Before I knew of the Governance Dashboard, I developed a very basic report that gives this information. I uploaded itno long ago:
If you are looking for monitoring tools, yes there are several moitoring tools available.
You may use this one: QlikView Governance Dashboard 1.0
Or the OPS Monitor here: http://community.qlik.com/docs/DOC-2614
By searching the community forum you will find others.
But I am not sure if this is what you are looking for.
i have already these tools but what i want to do is exactly the same thing as in Statistics.
Just get the current users and documents connected. And i want to do that every 30 seconds. To be able to make a status board.
The QMC probably just asks a question to the server which replies this list without parsing any logs .. somebody probably knows how to do without big documents
You may be able to extract the information you require using QMS API (QlikView Management Service) API. Here is a link to the document where you can search functions exposing QlikView information. The QMS API is a powerful API which can be used to manage user licenses, trigger tasks and many other functions.
I hope this is useful?
