直接贴shell脚本内容：

下面的脚本可以直接运行实时统计MySQL TPS/QPS/连接数等

#!/bin/bash

/usr/local/mysql/bin/mysqladmin extended-status -i1|awk 'BEGIN{local_switch=0;print "QPS Commit Rollback TPS Threads_con Threads_run \n ------------------------------------------------------- "}

$2 ~ /Queries$/ {q=$4-lq;lq=$4;}

$2 ~ /Com_commit$/ {c=$4-lc;lc=$4;}

$2 ~ /Com_rollback$/ {r=$4-lr;lr=$4;}

$2 ~ /Threads_connected$/ {tc=$4;}

$2 ~ /Threads_running$/ {tr=$4;

if(local_switch==0)

{local_switch=1; count=0}

else {
if(count>10)

{count=0;print "------------------------------------------------------- \n QPS Commit Rollback TPS Threads_con Threads_run \n ------------------------------------------------------- ";}

else{
count+=1;

printf "%-6d %-8d %-7d %-8d %-10d %d \n", q,c,r,c+r,tc,tr;

} }}'

.my.cnf配置文件:

[root@db-test ~]# cat /root/.my.cnf  
[client]
user=root
password=duuey356dsdxs  
host=127.0.0.1
port=3306

脚本实时输出内容:
