Filter wanted data columns
Here is a list of output from ftrace
, filtered by the pid
(12798
) of sample
program, then filtered with grep
:
sample-12798 [003] 42655.062100: sched_stat_runtime: comm=bash pid=12798 runtime=258929 [ns] vruntime=143898862 [ns] sample-12798 [001] 42655.062977: sched_stat_runtime: comm=sample pid=12798 runtime=864136 [ns] vruntime=94618957 [ns] ...
Print only the column of runtime
,
... | awk '{printf"%s\n", substr($7,9,length($7)-8)}'
Calculate the Sum
... | awk 'BEGIN {sum=0}{sum+=$1} END {print sum}'
