Hi Guys,
A few of you have been playing with the gdbprof fork that I made a while
back to profile some of the OSD and client side code. Last week I took
a day and cleaned the code up. I made a new repository/name for it here:
https://github.com/markhpc/gdbpmp
Some of the changes include being able to run it directly from the
commandline or within gdb, settings the sample count and sleep time,
filtering which threads to monitor, and saving the results so you can
re-parse the data (not super useful now, but eventually I'll try to
include different ways to examine the data, possibly things like
time-based correlation of events in different threads).
Adam is looking at writing a similar wallclock profiler that would use
libunwind directly and hopefully will be much faster, but for now
hopefully this will be easier and more useful than the earlier attempt.
Thanks,
Mark
