Hi,
I am interested in timestamped performance counter data (with a
specified sampling rate) as there is supposed to be saved in perf.data
when I use "perf record -T".
However, I don't understand the complete output of "perf report -D", and
can't figure out which parts of it are the timestamps. Is there any
documentation that I overlooked?
Actually if it helps, I am only interested in the name/raw event, value,
and timestamp, without any code/library information. Maybe the
information on which CPU it is from (on a multicore) could be
interesting as well.
Do I need to start looking into the code? Any good place to start? I
probably need to do this anyway, instead of parsing the really large
perf report -D output.
Use 'perf script' instead of 'perf report -D' to dump the samples.
