search for: ufunc

I''m trying to profile the time spent in libc functions in a large build job (building Perl), and I have trouble getting ufunc and func working. (func() is not strictly needed; I was just hoping to use it in order to profile idle time.) Here''s the story. I''ve written a dtrace script to start a separate dtrace process for each invoked command: int fileid; proc:::exec-success /pid == $target || progeny...

...to print out 2 levels of the stack, but what I''d like to be able to do is aggregate on the 2nd level entry up in the stack. Doesn''t appear to be a way to get a string back out of the ustack for an arbitrary call level that I could then put into an aggregation. Tried using the ufunc(uregs[R_PC]) but that''s just giving me the same as probefunc and in a form I can''t seem to print out in a composite aggregate. stack: layout-start trace-layout-entry() [extern C wrapper func] <C++ function from which trace-layout-entry() is being called and whose name we...

Is there any work on keeping DTraceTools up to date with the latest snv builds. These scripts are pretty useful and help get a novice dtrace user like me doing useful work quickly. Specifically the tcp stack tools like tcptop and tcpsnoop don''t work with later OpenSolaris builds. Thanks, Gary -- This message posted from opensolaris.org

Tracing Fans, I know it''s been a long time in coming but the CPU Performance Counter (CPC) provider is almost here! The code is currently in for review and a proposed architecture document is attached here for review. Any and all feedback/questions on the proposed implementation is welcome. Thanks.

hi, I am trying to find out the avg cpu time spent in each of my user methods (exclusive of other methods invoked by a method). Hence the following snippet failed miserably: ----------------------- pid$target:a.out::entry { time[probefunc] = timestamp;} pid$target:a.out::return { @spent[probefunc] = avg(timestamp - time[probefunc]);} END { printa(@spent);}
