Problem
I have a running/working OCS server (on Ubuntu 16.04) which already deployed some activated packages to my test-clients. So the basic setup works.
Currently i am wondering why "Information" -> "Log visualization" just shows a "NO RESULT" notification.
I am assuming it should display the content of /var/log/ocsinventory-server/activity.log or what else should be displayed there?
EDIT (as i cant find a comment or reply function)
The solution mentioned by Stéphane is working. As a result i got a table displayed featuring a downloadable .csv log file.
Just for the completness:
This .csv log contains in my case right now 8 lines, 5 of them are empty. the other 4 are covering a time of 6 seconds and do represent access to the webinterface by user, date, time, page and ip.
