Zabbix监控Redis

安装部署redis服务

• 安装redis

yum -y install redis

• 配置redis服，添加redis密码

echo "requirepass 123456" >> /etc/redis.conf

• 启动、开机自启服务

systemctl enable redis
systemctl start redis

获取redis信息的脚本

cat /server/scripts/reids_status.sh

#!/bin/bash
R_COMMAND="$1"
R_PORT="6379" #根据实际情况调整端口
R_SERVER="127.0.0.1" #根据具体情况调整IP地址
PASSWD="123456" #如果没有设置Redis密码,为空即可
redis_status(){
    (echo -en "AUTH $PASSWD\r\nINFO\r\n";sleep 1;) | /usr/bin/nc "$R_SERVER" "$R_PORT" > /tmp/redis_"$R_PORT".tmp
    REDIS_STAT_VALUE=$(grep "$R_COMMAND:" /tmp/redis_"$R_PORT".tmp | cut -d ':' -f2)
    echo "$REDIS_STAT_VALUE"
}

esac

给脚本添加执行权限

chmod +x /server/scripts/redis.sh

配置获取redis状态的key

[root@web03 ~]# cat /etc/zabbix/zabbix_agentd.d/redis_status.conf
UserParameter=redis_status[*],/bin/bash /server/scripts/redis_status.sh "$1"

重启agent服务

systemctl restart zabbix-agent

测试获取key值

#agent端测试
[root@web03 ~]# zabbix_agentd -t redis_status[used_cpu_user_children]
redis_status[used_cpu_user_children]          [t|0.00]

#server端测试
[root@zabbix-server ~]# zabbix_get  -s 172.16.1.9 -p 10050 -k redis_status[used_cpu_user_children]
0.00
