The missing systrace option in Android 4.3

The missing systrace option in Android 4.3

In Android 4.3, I did not find the "trace option" in setting->"Developer options".
And the python script(systrace.py) seems buggy, as this stackoverflow post told.

occasionally I find that "trace option" in eclipse.
Just like the image below:



This eclipse is extracted from latest android SDK, downloaded from here.
Now, I can use systrace as Android4.2.
