There are many more stats on buildstats that 'Elapsed time', so make the script more flexible to support all stats. Some cmd line examples: $ buildstats.sh -s 'utime' Buildstats' data covers proc's stats in different areas, including CPU times, IO, program system resources and child program system resources. In order to print values on each of these sets from command line, one can use the following: $ buildstats.sh -H -s 'TIME' | less $ buildstats.sh -H -s 'IO' | less and 'RUSAGE' and 'CHILD_RUSAGE' for program and program's child system resources.

# DESCRIPTION
|
|
# Given 'buildstats' data (generate by bitbake when setting
|
|
# USER_CLASSES ?= "buildstats" on local.conf), task names and a stats values
|
|
# (these are the ones preset on the buildstats files), outputs
|
|
# '<task> <recipe> <value_1> <value_2> ... <value_n>'. The units are the ones
|
|
# defined at buildstats, which in turn takes data from /proc/[pid] files
|
|
#
|
|
# Some useful pipelines
|
|
#
|
|
# 1. Tasks with largest stime (Amount of time that this process has been scheduled
|
|
# in kernel mode) values
|
|
# $ buildstats.sh -b <buildstats> -s stime | sort -k3 -n -r | head
|
|
#
|
|
# 2. Min, max, sum utime (Amount of time that this process has been scheduled
|
|
# in user mode) per task (in needs GNU datamash)
|
|
# $ buildstats.sh -b <buildstats> -s utime | datamash -t' ' -g1 min 3 max 3 sum 3 | sort -k4 -n -r
