Google profiler should use build IDs for symbol resolution
	We use build IDs and a file share with carefully arrange symbols to let gdb automatically find our symbols, as described here: [link] It's quite convenient knowing that the debugger will reliably and automatically find symbols for us and it makes debugging build-machine... more » By bruce.daw...@gmail.com  - Dec 18 2012 - 3 new of 3 messages

	What does "No live heap object" mean in the heap checker?
	Hi, after problems with the profliing part I am hitting more problems with the heap checker. I am using local heap checking. My code is a straight copy from the documentation: HeapLeakChecker heap_checker("test_foo"); { int *i = new int[10]; ...if (!heap_checker.NoLeaks()) assert(NULL == "heap memory leak");... more » By Enrico Zschemisch  - Nov 29 2012 - 2 new of 2 messages

TCMalloc heap profiler in release build of OSX Chrome

Should I expect this to produce heap profiling data if the Chrome build is a standard OSX release build downloaded from the official Chrome site? Where "this" is: ~$ HEAPPROFILE=/Users/aalness/hea pprofile "/Applications/Google Chrome.app/Contents/MacOS/Goog le Chrome" I currently don't see any profiling data being produced, however, if I... more » By andrew alness  - Nov 28 2012 - 2 new of 2 messages

Speeding up pprof execution time

I am contemplating speeding up pprof execution time. I did a profiling of pprof (!!) over many varying duration runs. Although I have not yet reached any conclusive results yet, it seems to be the case that main::ReadCPUProfile and the obj tools like nm and addr2line take up most of the execution time. Does anyone have any prior experience in trying to... more » By Ram  - Nov 27 2012 - 1 new of 1 message

	How to initialise the CPU profiler manually?
	Hi, I have the following situation: A linux binary is searching a specific directory for shared libraries. All found shared libraries are later used as a plugin. Now the binary sets signal handlers for everything and exits when it gets *any* signal. The binary can not be used with -fPIC-compiled... more » By Enrico Zschemisch  - Nov 15 2012 - 6 new of 6 messages

	using tcmalloc with tbb, activemq and boost
	I'll try my best to explain what is going on, not sure where to post this since I can't quite figure out what the root cause of the issue is. I updated an old release of my code base to use tcmalloc and it works fine. Updating a newer release of the same code base I am having issues with seg faults.... more » By Quintin Cummins  - Nov 7 2012 - 5 new of 5 messages

	CPU Profiler: What are your suggestions to retrieve a subset of cpu profiler data
	I am working on a requirement where I would like to extract a subset of CPU profiler data. To elaborate, let's say I ran the profiler from t=0 to t=100 seconds (for simplicity sake) . My profiler run is only once over the whole lifetime of the program (t=0 to t=100), which means I will have only one .prof file... more » By Ramachandran Eswaran  - Nov 5 2012 - 2 new of 2 messages

	Using gperftools, not able to see all nodes in the call graph of the lower dependencies
	Hi, I have been trying to use google perftools to profile my product, but facing a few issues. We have a dependency like this - main_server (deamon running which will take up all the DNS queries coming in) Then it will make the threads to take care of dns resolutions, and that library is thread_lib.... more » By Deepak Vijayvergiy  - Nov 5 2012 - 11 new of 11 messages

	graph doesn't account for 100% cumulative CPU time
	[duplicate of [link] which I posted before discovering this group] I've got a postscript call graph whose root nodes don't total up to anywhere near 100% cumulative time. I'm wondering if anyone has dealt with this before. 1. pprof's text output's third column, the running total of local times, does add up to 100% on the last row.... more » By vibhu  - Oct 30 2012 - 1 new of 1 message
