Tool for analyzing output of perf tool: `$ perf script`

Project description

# perf-script-postprocessor

[![Build Status](https://travis-ci.org/arcolife/perf-script-postprocessor.svg?branch=master)](https://travis-ci.org/arcolife/perf-script-postprocessor)

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](https://github.com/brendangregg/perf-tools)

## INSTALLATION

Step 1: Install from pip: $ pip2 install perf-script-postprocessor

Step 2: Copy [this conf file](https://raw.githubusercontent.com/arcolife/perf-script-postprocessor/master/delta_processor.conf)
into /etc/

Step 3: Customize the conf file accordingly.

Optional: Step 4: Refer to docs/WIKI.md or [this page](https://github.com/arcolife/perf-script-postprocessor/wiki) for detailed usage.

For more, refer to INSTALL guide.

## TESTS

$ ./tests/run-tests.sh

## USAGE

`$ perf_script_processor -p <dir path> -t <test type>`

Example: `$ 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 script is run on folder containing perf.data
  • perf_data.csv – generated in the process of generating results

-t (defaults to 0) is either 0 or 1. It’s the type of test that generated perf.data.

  • 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.
