# DESCRIPTION
|
#
|
# 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

Usage: $CMD [-b buildstats_dir] [-t do_task]
|
-b buildstats The path where the folder resides
|
(default: "$BS_DIR")
|
-n N Top N recipes to display. Ignored if -S is present
|
(default: "$N")
|
-r recipe The recipe mask to be searched
|
-t tasks The tasks to be computed
|
(default: "$TASKS")
|
-s stats The stats to be matched. If more that one stat, units
|
should be the same because data is plot as histogram.
|
(see buildstats.sh -h for all options) or any other defined
|
(build)stat separated by colons, i.e. stime:utime
|
(default: "$STATS")
|
-a Accumulate all stats values for found recipes
|
-S Sum values for a particular stat for found recipes
|
-o Output data file.
|
(default: "$OUTDATA_FILE")
|
