- # 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
