Hello,
I know that questions on tools are not relevant for this cocoa-dev, but I
couldn’t find any relevant mailing list for tools like ‘sample’ or sampling
using Activity Monitor GUI tool.
So, let me ask it here, because all Cocoa programmers use such tools whenever
needed.
I have a process sample like this.
Call graph:
1379 Thread_839846: Main Thread DispatchQueue_<multiple>
+ 1379 start (in Wirecast) + 52 [0x100a31074]
+ 1379 main (in Wirecast) + 1070 [0x100b3e16a]
+ 1379 eApp::Run(bool, zRecord*) (in libeva.dylib) + 779 [0x101033225]
+ 1379 eWindowManager_cocoa::MessageLoop() (in libeva.dylib) + 70
[0x101037932]
+ 1379 -[NSApplication run] (in AppKit) + 594 [0x7fff88cd2593]
I can guess the number on the 1st (2nd?) on every row after + sign. It should
be number of samples or how long a method/function take.
According to MAN page for ‘sample’, it samples at every 1 msec.
And http://stackoverflow.com/questions/10709577/spindump-analysis-instructions
<http://stackoverflow.com/questions/10709577/spindump-analysis-instructions>
says, it’s the number of samples.
By looking at the numbers on children nodes, I guess so too. But is it really
so?
If there is a better mailing list for this kind of inquiry, please let me know.
Thanks,
JongAm Park
