I'm trying to set up Task performance summary as described in the release notes, but is just not working. I already have a support case with Qlik but maybe there is somebody that already faced and solved this issue.
23/01/2015 08:47:25.1755937 Information Failed to initilaize CPU and Memory monitor. Process summary will not be available.
I added the line to settings.ini leaving last line in blank, restarted Distribution Service, deleted Distribution Service folder and, by Qlik Support recomendation, re-register qvb.exe by rigth clicking the file and runing as administrator.
Unfortunately there is no way get the exact reason for this. But it is based on Windows Performance Counters so I would recommend you to open this on the server machine and make sure you don't see any errors.
Especially look for the counter. '\Processor(_Total)\% Processor Time'
Also look in the Windows Event Viewer for any errors or warnings related to Performance Counters.
