open chrome, enter "chrome://tracing", and click the "load" button to load your trace html file.
It might be used incorrectly parameters in systrace. The correct command is here, please try it.
python ./systrace.py -t 5 -o ./trace.html gfx input view webview wm am sm audio video camera hal app res dalvik rs bionic power sched irq freq idle disk mmc load sync workq memreclaim regulators
Using systrace of catapult project, not in Android SDK worked for me.
$ git clone https://github.com/catapult-project/catapult.git
$ ./catapult/systrace/bin/systrace
