20 | # DESCRIPTION | ||
21 | # | ||
22 | # Produces script data to be consumed by gnuplot. There are two possible plots | ||
23 | # depending if either the -S parameter is present or not: | ||
24 | # | ||
25 | # * without -S: Produces a histogram listing top N recipes/tasks versus | ||
26 | # stats. The first stat defined in the -s parameter is the one taken | ||
27 | # into account for ranking | ||
28 | # * -S: Produces a histogram listing tasks versus stats. In this case, | ||
29 | # the value of each stat is the sum for that particular stat in all recipes found. | ||
30 | # Stats values are in descending order defined by the first stat defined on -s | ||
31 | # | ||
32 | # EXAMPLES | ||
33 | # | ||
34 | # 1. Top recipes' tasks taking into account utime | ||
35 | # | ||
36 | # $ buildstats-plot.sh -s utime | gnuplot -p | ||
37 | # | ||
38 | # 2. Tasks versus utime:stime | ||
39 | # | ||
40 | # $ buildstats-plot.sh -s utime:stime -S | gnuplot -p | ||
41 | # | ||
42 | # 3. Tasks versus IO write_bytes:IO read_bytes | ||
43 | # | ||
44 | # $ buildstats-plot.sh -s 'IO write_bytes:IO read_bytes' -S | gnuplot -p | ||
