I don't know if it's the same in QlikSense - I'm working with QlikView - but here, there are two places where to look for log_files - the directory where the apps are stored (there is only one log there, always overwritten) and the QlikView_Distribution_Service written to the installation directories where all the old log_files are kept, sorted by day and time in subfolders.
There is, however, only one setting for the logging in general - it's either on or off in both locations.
We had the same issue rgd. the space on the QlikViewServer (installation directories) with the old log_files clogging it up - the IT_guys are now cleaning that up every 30d. You could also use a small batch file to do that.
Hi Avinash, to go to that page you can click on engines in qmc menu:
If you click on "Engines" it opens your installed engines, Double-click on one of them (by default there is only one, called Central), once is open, on the right margin select "logging" to display the logging and tracing sections.
I can't tell you wich are the best options, I'm still a newbie on this.
