zabbix 监控 mysql数据库状态脚本实现_zabbix实时监控mysql业务数据

1. 实验环境

1.1 服务器均为centos7操作系统

1.2 服务器ip地址

zabbix-server ip：192.168.153.183
zabbix-agent ip： 192.168.153.185

1.3 均关闭防火墙和selinux

关闭防火墙

systemctl stop firewalld
1

关闭selinux

setenforce 0
1

2. agent端配置

2.1 在agent端创建存放脚本的目录

[root@localhost ~]# cd /etc/zabbix/
[root@localhost zabbix]# mkdir scripts
[root@localhost scripts]# pwd
/etc/zabbix/scripts
1

2.2 编写监控mysql的脚本并增加执行权限

2.2.1 脚本内容

[root@localhost scripts]# cat mysql.sh 
#!/bin/bash

# 用户名
MYSQL_USER='zabbix'

# 密码
MYSQL_PWD='123'

# 主机地址/IP
MYSQL_HOST='192.168.153.185'

# 端口
MYSQL_PORT='3306'

# 数据连接
MYSQL_CONN="/usr/bin/mysqladmin -u${MYSQL_USER} -p${MYSQL_PWD} -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 $result 
                ;; 
    Questions) 
        result=`${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 $result 
                ;; 
    Com_delete) 
        result=`${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)" 
        ;;

1

将第5行修改为以下内容

  5 UserParameter=mysql.status[*],/etc/zabbix/scripts/mysql.sh  $1
1

保存退出后重启agent服务

systemctl restart zabbix-agent
1

3. 在server端进行测试

返回数据成功

[root@localhost ~]# zabbix_get -s 192.168.153.185 -k mysql.status[Uptime]
645
[root@localhost ~]# zabbix_get -s 192.168.153.185 -k mysql.status[Com_update]
