Once an event file is generated and transferred back to the development host for analysis (whether it was done automatically by the IDE or generated by using tracelogger and manually imported into the IDE), you can then invoke the System Profiler editor.
If this happens, restart qconn with the qconn_prio= option to specify a higher priority. You can use hogs or pidin to see which process is keeping the target busy, and discover its priority.
The IDE includes a custom perspective for working with the System Profiler. This perspective sets up some of the more relevant views for easy access.
