我是靠谱客的博主安详草莓，最近开发中收集的这篇文章主要介绍MySQL获取系统性能和状态代码，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

复制代码代码如下:

 
#!/bin/ksh 
INTERVAL=5 
PREFIX=$INTERVAL-sec-status 
touch /tmp/running 
RUNFILE=/tmp/running 
my -e 'show global variables' >> mysql-variables 
while test -e $RUNFILE; do 
file=$(date +%F_%I) 
sleep=$(date +%s.%N | awk "{print $INTERVAL - (\$1 % $INTERVAL)}") 
sleep $sleep 
ts="$(date +"TS %s.%N %F %T")" 
loadavg="$(uptime)" 
echo "$ts $loadavg" >> $PREFIX-${file}-status 
my -e 'show global status' >> $PREFIX-${file}-status & 
echo "$ts $loadavg" >> $PREFIX-${file}-innodbstatus 
my -e 'show engine innodb status\G' >> $PREFIX-${file}-innodbstatus & 
echo "$ts $loadavg" >> $PREFIX-${file}-processlist 
my -e 'show full processlist\G' >> $PREFIX-${file}-processlist & 
echo $ts 
done 
echo Exiting because $RUNFILE does not exist.
