Re: The same app name and symbol name

Hi Michael,

Here is my code:

#!/bin/sh


echo "Delete previous files"

rm -rf test*

rm -rf /tmp/test*

rm -rf op-re*


echo "Start OProfile"

nohup sudo operf --system-wide --separate-thread --separate-cpu > /dev/null
&


echo "Start Tests"

dbt2-run-workload -c 20 -a pgsql -d 100 -w 10 -n -o /tmp/test8 > test8

echo "Finish Tests"


echo "Start Generating Report"

#sudo opreport --demangle=smart --symbols --long-filenames --merge tgid
$(which postgres) -o ./op-result-postgres

sudo opreport --demangle=smart --symbols --long-filenames --merge all -o
./op-result-postgres

echo "Finish Generating Report"


sudo pkill operf

echo "Finish OProfile"


Thanks,
Tim
