Zabbix 监控Mysql

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 $result
;;
Com_update)
            result=`/usr/bin/mysqladmin -u$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 $result
                ;;
    Com_rollback)
        result=`/usr/bin/mysqladmin -u$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}‘

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]";  

6、添加zabbix管理页面添加服务
