zabbix监控mysql的性能

参考 http://www.linuxidc.com/Linux/2016-04/130436.htm
环境：
zabbix sever: 192.168.234.131
mysql :192.168.234.130

mysql 客户端操作：

1 添加监控用户，登入到数据里然后：

GRANT USAGE ON *.* TO 'zabbix'@'localhost' IDENTIFIED BY 'zabbix' WITH GRANT OPTION;
MariaDB [(none)]>  flush privileges;      ##刷新系统授权
MariaDB [(none)]> grant all on zabbix.* to 'zabbix'@'127.0.0.1' identified by 'zabbix' with grant option;

2 编写脚本 vi /usr/local/zabbix/scripts/mysql_status.sh

User='zabbix'
Password='zabbix'
Mysql='/usr/bin/mysql'
Mysqladmin='/usr/bin/mysqladmin'
command(){
$Mysql -u $User -p$Password -e "show global status" | awk '$1 ~ /'"$1"'$/ {print $2}'
}
case $1 in
Com_select)
command $1 ;;
Com_insert)
command $1 ;;
Com_update)
command $1 ;;
Com_delete)
command $1 ;;
Com_begin)
command $1 ;;
Com_commit)
command $1 ;;
Com_rollback)
command $1 ;;
Questions)
command $1 ;;
Slow_queries)
command $1 ;;
Bytes_received)
command $1 ;;
Bytes_sent)
command $1 ;;
Uptime)
command $1 ;;
Version)
$Mysql -V | awk -F '[ ,]' '{print $6}' ;;
Ping)
$Mysqladmin -u$User -p$Password ping | wc -l ;;
*)
echo "Usage: $0 { Com_select|Com_insert|Com_update|Com_delete|Com_begin|Com_commit|Com_rollback|Questions|Slow_queries|Bytes_received|Bytes_sent|Ping|Uptime|Version }" ;;
esac

3、添加自定义 key 配置文件

vi /usr/local/zabbix/etc/zabbix_agentd.conf
UserParameter=mysql.status[*],/usr/local/zabbix/scripts/mysql_status.sh $1
UserParameter=mysql.ping,/usr/local/zabbix/scripts/mysql_status.sh Ping
UserParameter=mysql.version,/usr/local/zabbix/scripts/mysql_status.sh Version

4 重启zabbix_agentd服务
/etc/init.d/zabbix_agentd restart
5 最后可以在服务端验证
zabbix_get -s 192.168.234.130 -k mysql.ping
如果返回1即是正常
6 添加zabbix自带的mysql模板，确认出图
1)在zabbix前端可以实时查看mysql发送接收的字节数。其中bytes received表示从所有客户端接收到的字节数，bytes sent表示发送给所有客户端的字节数。



2)实时查看SQL语句每秒钟的操作次数
