Hi Nicholas Yeah right, pidstat which read /proc gives me VSZ ans RSS but i need to backtrace when VSZ/RSS is high which indicates process is allocating memory which it is not even using. And to modify the question i need to analyze allocations per thread, using /proc will it will also include VSZ RSS of parent.?
