Zabbix监控MySQL性能

由于MySQL5.7版本以上在命令行中不允许使用明文密码,所以需要将用户名和密码存在文件中:
认证信息文件内容如下:

[client]

user=zabbix

password="shengyan777.com"

 

监控MySQL的shell脚本内容如下:

#!/bin/bash
# -------------------------------------------------------------------------------
# FileName:    check_mysql.sh
# Revision:    1.0
  
# 主机地址/IP
MYSQL_HOST='127.0.0.1'
 
# 端口
MYSQL_PORT='3306'
 
# 数据连接
MYSQL_CONN="/usr/bin/mysqladmin --defaults-file=/etc/zabbix/scripts/mysqluser -h${MYSQL_HOST} -P${MYSQL_PORT}"
 
# 参数是否正确
if [ $# -ne "1" ];then 
    echo "arg error!" 
fi 
 
# 获取数据
case $1 in 
    Uptime) 
        result=`${MYSQL_CONN} status|cut -f2 -d":"|cut -f1 -d"T"` 
        echo $result 
        ;; 
    Com_update) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_update"|cut -d"|" -f3` 
        echo $result 
        ;; 
    Slow_queries) 
        result=`${MYSQL_CONN} status |cut -f5 -d":"|cut -f1 -d"O"` 
        echo $result 
        ;; 
    Com_select) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_select"|cut -d"|" -f3` 
        echo $result 
                ;; 
    Com_rollback) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_rollback"|cut -d"|" -f3` 
                echo $result

        result=`${MYSQL_CONN} status|cut -f4 -d":"|cut -f1 -d"S"` 
                echo $result 
                ;; 
    Com_insert) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_insert"|cut -d"|" -f3` 
                echo $result

        result=`${MYSQL_CONN} extended-status |grep -w "Com_delete"|cut -d"|" -f3` 
                echo $result 
                ;; 
    Com_commit) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_commit"|cut -d"|" -f3` 
                echo $result 
                ;; 
    Bytes_sent) 
        result=`${MYSQL_CONN} extended-status |grep -w "Bytes_sent" |cut -d"|" -f3` 
                echo $result 
                ;; 
    Bytes_received) 
        result=`${MYSQL_CONN} extended-status |grep -w "Bytes_received" |cut -d"|" -f3` 
                echo $result 
                ;; 
    Com_begin) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_begin"|cut -d"|" -f3` 
                echo $result 
                ;; 
                        
        *) 
        echo "Usage:$0(Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions|Com_insert|Com_delete|Com_commit|Bytes_sent|Bytes_received|Com_begin)" 
        ;; 
esac

 

在zabbix客户端的配置文件中添加以下内容:

[root@120 ~]# vim /etc/zabbix/zabbix_agentd.conf

UserParameter=mysql.version,mysql -V
UserParameter=mysql.status[*],/etc/zabbix/scripts/mysql-replication.sh $1
UserParameter=mysql.ping,sudo netstat -tnlp|egrep -i "mysql"|awk {'print $4'}|awk -F':' '{if ($NF~/^[0-9]*$/) print $NF}'|wc -l

 

登陆zabbix,点击Configuration –> Hosts,编辑监控主机,将Template App MySQL模板链接到监控主机的Templates中

到此,MySQL的监控就配置完成了。点击Monitoring –> Graphs ,选择mysql,过几分钟就能出图了
