Hi,
I record three different events for my test-program:
perf record -s -e cycles,instructions,LLC-load-misses ./test-program
I want to plot the occurences of the different events over time, i.e.
x-axis is time and y-axis is event count.
With
perf report -D
I can dump perf.data to ASCII. However, I could not figure out how to
extract different event types from the ASCII output.
0x1edb88 [0x30]: event: 9
.
. ... raw event: size 48 bytes
. 0000: 09 00 00 00 02 00 30 00 43 b6 2f e7 52 2b 00 00 ......0.C./.R+..
. 0010: 2b 20 01 00 2f 20 01 00 2e 21 8e 48 b4 a9 26 00 + ../ ...!.H..&.
. 0020: f6 6d 00 00 00 00 00 00 6b 60 63 00 00 00 00 00 .m......k`c.....

10882640891486510 0x1edb88 [0x30]: PERF_RECORD_SAMPLE(IP, 2):
73771/73775: 0x2b52e72fb643 period: 6512747 addr: 0
I figured out how to parse the timestamp, pid and pid and I guess period
says how often an event happened in the period. However I do not know
which event occured. Is this only encoded in the raw event or am I
missing something?
