Zabbix 监控Mysql

Posted 2020-11-24 项思凯

简介

通过 zabbix 默认的mysql监控模板，来监控Mysql数据库，但是直接使用是无法引用模板监控的，需要进行如下配置方可使用。

环境

• 服务：Zabbix 3.0.28、zabbix-agent  2.4.7
• 系统：Linux Centos7/Redhat7

部署

操作zabbix-agent客户端

1、在被监控数据库内创建监控账号

mysql -uroot -p

GRANT PROCESS,SUPER,REPLICATION CLIENT ON *.* TO mysqlcheck@\'192.168.0.8\' IDENTIFIED BY \'mysqlcheck\';

2、创建mysql监控脚本

vim /etc/zabbix/chk_mysql.sh

#!/bin/sh
MYSQL_SOCK="/var/lib/mysql/mysql.sock"
MYSQL_USER=\'mysqlcheck\'
MYSQL_PWD=\'mysqlcheck\'
MYSQL_HOST=\'192.168.0.8\'
MYSQL_PORT=\'3307\'
ARGS=1

if [ $# -ne "$ARGS" ];then
    echo "Please input one arguement:"
fi

case $1 in
Uptime)
  result=`/usr/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -P${MYSQL_PORT} -S $MYSQL_SOCK status  2>/dev/null|cut -f2 -d":"|cut -f1 -d"T"`
  echo $result
;;

            result=`/usr/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -P${MYSQL_PORT} -S $MYSQL_SOCK extended-status  2>/dev/null|grep -w "Com_update"|cut -d"|" -f3`
            echo $result
            ;;
        Slow_queries)
        result=`/usr/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -P${MYSQL_PORT} -S $MYSQL_SOCK status  2>/dev/null |cut -f5 -d":"|cut -f1 -d"O"`
                echo $result
                ;;
    Com_select)
        result=`/usr/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -P${MYSQL_PORT} -S $MYSQL_SOCK extended-status  2>/dev/null |grep -w "Com_select"|cut -d"|" -f3`
                echo $result
                ;;

        result=`/usr/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -P${MYSQL_PORT} -S $MYSQL_SOCK extended-status  2>/dev/null |grep -w "Com_rollback"|cut -d"|" -f3`
                echo $result
                ;;
    Questions)
        result=`/usr/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -P${MYSQL_PORT} -S $MYSQL_SOCK status  2>/dev/null|cut -f4 -d":"|cut -f1 -d"S"`
                echo $result
                ;;
    Com_insert)
        result=`/usr/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -P${MYSQL_PORT} -S $MYSQL_SOCK extended-status  2>/dev/null |grep -w "Com_insert"|cut -d"|" -f3`
                echo $result
                ;;
    Com_delete)
        result=`/usr/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -P${MYSQL_PORT} -S $MYSQL_SOCK extended-status  2>/dev/null |grep -w "Com_delete"|cut -d"|" -f3`
                echo $result
                ;;
    Com_commit)
        result=`/usr/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -P${MYSQL_PORT} -S $MYSQL_SOCK extended-status  2>/dev/null |grep -w "Com_commit"|cut -d"|" -f3`
                echo $result
                ;;
    Bytes_sent)
        result=`/usr/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -P${MYSQL_PORT} -S $MYSQL_SOCK extended-status  2>/dev/null |grep -w "Bytes_sent" |cut -d"|" -f3`
                echo $result
                ;;
    Bytes_received)
        result=`/usr/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -P${MYSQL_PORT} -S $MYSQL_SOCK extended-status  2>/dev/null|grep -w "Bytes_received" |cut -d"|" -f3`
                echo $result
                ;;
    Com_begin)
        result=`/usr/bin/mysqladmin -u$MYSQL_USER -h$MYSQL_HOST -p${MYSQL_PWD} -P${MYSQL_PORT} -S $MYSQL_SOCK extended-status  2>/dev/null|grep -w "Com_begin"|cut -d"|" -f3`
                echo $result
                ;;        
        *)
        echo "Usage:$0(Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions)"
        ;;
esac

3、添加权限

chmod 755 chk_mysql.sh

4、修改添加zabbix-agent配置文件

UnsafeUserParameters=1
UserParameter=mysql.version,mysql -V
UserParameter=mysql.status[*],/etc/zabbix/chk_mysql.sh $1
UserParameter=mysql.ping,netstat -ntpl |grep 3307 |grep mysql |wc |awk \'{print $1}\'

# 通过端口号判断mysql存活
UserParameter=mysql.ping,netstat -ntpl |grep 3317 |grep mysql |wc|awk \'{print $1}\'

其他

5、重启zabbix-agent

systemctl restart zabbix-agentd

# 服务端测试
zabbix_get -s 10.x.x.x -p10050 -k "system.cpu.load[all,avg15]";  

测试

6、添加zabbix管理页面添加服务
