# Redis 메모리 & 시간 측정 스크립트

 

Python으로 redis 테스트 시 메모리와 시간 측정을 위한 스크립트

### flushall execution

before=`redis-cli INFO memory | grep 'used_memory:' | awk -F: '{print $2}'`

### test execution
echo "[Info] test start"
################################################ 테스트 실행 파일
python3 $INPUT_FILE

### check memory and time after test
after=`redis-cli INFO memory | grep 'used_memory:' | awk -F: '{print $2}'`
a=`echo "${after//[$'\t\r\n ']}"`
EndTime=$(date +%s)
  
used=$(expr $a - $b)
  
echo ""

echo "####################################[result]################################################"
echo "[result] redis used memory ${used}"
echo "[result] It takes $(($EndTime - $StartTime)) seconds to complete this task."
