From 74408c19fba89de54c093fccf65b3a072d6a197b Mon Sep 17 00:00:00 2001 From: Leonardo Sandoval Date: Tue, 15 Nov 2016 15:19:53 -0600 Subject: bb-perf: plot histograms base on buildstats data Scripts that produces script data to be consumed by gnuplot. There are two possible plots depending if either the -S parameter is present or not: * without -S: Produces a histogram listing top N recipes/tasks versus stats. The first stat defined in the -s parameter is the one taken into account for ranking * -S: Produces a histogram listing tasks versus stats. In this case, the value of each stat is the sum for that particular stat in all recipes found. Stats values are in descending order defined by the first stat defined on -s EXAMPLES 1. Top recipes' tasks taking into account utime $ buildstats-plot.sh -s utime | gnuplot -p 2. Tasks versus utime:stime $ buildstats-plot.sh -s utime:stime -S | gnuplot -p 3. Tasks versus IO write_bytes:IO read_bytes $ buildstats-plot.sh -s 'IO write_bytes:IO read_bytes' -S | gnuplot -p Signed-off-by: Leonardo Sandoval Signed-off-by: Ross Burton --- scripts/contrib/bb-perf/buildstats-plot.sh | 157 +++++++++++++++++++++++++++++ 1 file changed, 157 insertions(+) create mode 100755 scripts/contrib/bb-perf/buildstats-plot.sh (limited to 'scripts/contrib') diff --git a/scripts/contrib/bb-perf/buildstats-plot.sh b/scripts/contrib/bb-perf/buildstats-plot.sh new file mode 100755 index 0000000000..7e8ae0410e --- /dev/null +++ b/scripts/contrib/bb-perf/buildstats-plot.sh @@ -0,0 +1,157 @@ +#!/usr/bin/env bash +# +# Copyright (c) 2011, Intel Corporation. +# All rights reserved. +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
