dell物理服务器硬件磁盘监控

物理服务器硬件磁盘监控:


第一:安装Megacli 和 zabbix_sender 

MegaCli

参考:http://tenderrain.blog.51cto.com/9202912/1639865

rpm -ivh megacli-8.02.21-1-mdv2012.0.x86_64.rpm

查看安装路径(不同的安装包路径可能不同);

rpm -ql megacli-8.02.21-1.x86_64

/sbin/megacli

/usr/share/doc/megacli

/usr/share/doc/megacli/8.02.21_MegaCLI.txt


zabbix_sender

默认已安装,如果没有这个命令,可从其他服务器拷贝



第二:

#部署脚本

文件一:/usr/local/raid_and_disk_check.sh

#/bin/bash

#Function:

#1.check raid Degraded

#2.check Failed Disks

zabbix_sender -c /etc/zabbix/zabbix_agentd.conf -k "raid_degraded" -o `sudo megacli -AdpAllInfo -aALL -NoLog | grep "Degraded" |awk '{print $NF}'` -r 

zabbix_sender -c /etc/zabbix/zabbix_agentd.conf -k "raid_failed_disks" -o `sudo megacli -AdpAllInfo -aALL -NoLog | grep "Failed Disks" |awk '{print $NF}'` -r 


chown zabbix.zabbix /usr/local/raid_and_disk_check.sh

chmod +x /usr/local/raid_and_disk_check.sh


文件二:/usr/local/disk_id_discover.sh

#!/bin/bash

#Function:

#1.check Disk of Slot Number

num=0

RAID_stats() {

DISK=($(sudo megacli -pdlist -aALL | grep "Slot Number" | awk -F":" '{print $2}'))

printf '{\n\t"data":[\n'

for key in ${DISK[@]};do

        if [[ "${#DISK[@]}" -gt "$num" && "$num" -ne "$((${#DISK[@]}-1))" ]];then

        printf "\t\t{\"{#RAID_ID}\":\"$key\"},\n"

        let "num++"

        elif [[ "$((${#DISK[@]}-1))" -eq "$num" ]];then

        printf "\t\t{\"{#RAID_ID}\":\"$key\"}\n"

        fi

done

printf '\t]\n}\n'

}

RAID_stats


chown zabbix.zabbix /usr/local/disk_id_discover.sh

chmod +x /usr/local/disk_id_discover.sh


备注:

- megacli:改成正确的路径

- 确保zabbix用户有权限使用这个命令

- disk_id_discover.sh 生成的数据是字典的格式


第三:修改zabbix的配置文件:

备份:

\cp -r /etc/zabbix/zabbix_agentd.conf /etc/zabbix/zabbix_agentd.conf.bak 

修改:

cat >> /etc/zabbix/zabbix_agentd.conf << EOF  

UnsafeUserParameters=1

UserParameter=raid_discover,bash /usr/local/raid_id_discover.sh

UserParameter=raid_degraded,sudo /usr/local/MegaCli -AdpAllInfo -aALL -NoLog | grep "Degraded" |awk '{print \$NF}'

UserParameter=raid_failed_disks,sudo /usr/local/MegaCli -AdpAllInfo -aALL -NoLog | grep "Failed Disks" |awk '{print \$NF}'

UserParameter=raid_MEC[*],sudo /usr/local/MegaCli -PDList -aAll -NoLog | grep -A 8 "Slot Number: \$1" | grep "Media Error Count" | awk '{print \$NF}'

UserParameter=raid_OEC[*],sudo /usr/local/MegaCli -PDList -aAll -NoLog | grep -A 8 "Slot Number: \$1" | grep "Other Error Count" | awk '{print \$NF}'

EOF


第四:给zabbix添加sudo权限(这块可以优化,有风险)

echo "zabbix ALL=(root) NOPASSWD:ALL" >> /etc/sudoers

sed -i 's/^Defaults.*.requiretty/#Defaults    requiretty/'  /etc/sudoers

第五:

重启zabbix服务


第六:添加至crontab

echo "01 02 * * * root  /usr/local/raid_and_disk_check.sh >/dev/null 2>&1 " >> /etc/crontab

echo "01 02 * * * root  /usr/local/disk_id_discover.sh >/dev/null 2>&1" >> /etc/crontab


第七:zabbix模板设置,此处省略,补充下模板参考附件RAID_and_disk_check_for_dell(可能需要微微修改)
