mysql压力测试与qps监控

https://blog.csdn.net/csd753111111/article/details/100428512

脚本：

#cat mysql_qps.sh 

#!/bin/bash

MYSQL_CON="/usr/local/mysql/bin/mysql"

TIME="$1"

OLD_QUERY=`$MYSQL_CON -e "show global status like 'questions';" | awk -F[' ','s'] 'NR==2{print $3}'`

echo "$OLD_QUERY"

sleep "$TIME"

NEW_QUERY=`$MYSQL_CON -e "show global status like 'questions';" | awk -F[' ','s'] 'NR==2{print $3}'`

echo "$NEW_QUERY"

TIME_QUERY=`expr $NEW_QUERY - $OLD_QUERY`

QPS=`expr $TIME_QUERY / $TIME`

echo "$QPS"

0状态
