This calculates delta (difference of timestamps from various
entry/exit points from events recorded) from the trace output,
which is produced by using the
perf script command, which in turn,
uses the perf.data file produced by using the
perf record command,
a set of utilities,which is provided under the package perf-tools
Step 1: Install from pip:
$ pip2 install perf-script-postprocessor
Step 2: Copy this conf file into /etc/
Step 3: Customize the conf file accordingly.
Optional: Step 4: Refer to docs/WIKI.md or this page for detailed usage.
For more, refer to
$ perf_script_processor -p <dir path> -t <test type>
$ perf_script_processor -p . -t 0
-p (defaults to
/tmp/pp_results) is where one of the following exists:
- perf.data -- binary file. If you're running this tool on perf.data, make sure you're running it from the system where the binary was generated
- raw_perf -- plain text output when
perf scriptis run on folder containing perf.data
- perf_data.csv -- generated in the process of generating results
-t (defaults to
0) is either
1. It's the type of test that generated
- 0: Native
- 1: Threads
NOTE: The stats at the end of run, will be stored in
delta_output.log in folder where you've generate the output.
