##通過zabbix監控機房硬盤狀態，減少跑機房次數，提前進行硬盤故障預警。

#親測可以使用的腳本

• 準備包

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

通過salt直接安裝到每臺服務器

• 修改zabbix_agentd配置

增加配置文件

raid_check.conf

UserParameter=raid.phy.discovery,sudo /usr/local/zabbix/scripts/RaidCheck.py pd_discovery

UserParameter=raid.phy.mec[*],sudo /usr/local/zabbix/scripts/RaidCheck.py mec $1

UserParameter=raid.phy.oec[*],sudo /usr/local/zabbix/scripts/RaidCheck.py oec $1

UserParameter=raid.phy.pfc[*],sudo /usr/local/zabbix/scripts/RaidCheck.py pfc $1

UserParameter=raid.phy.fw_state[*],sudo /usr/local/zabbix/scripts/RaidCheck.py fw_state $1

Zabbix_agentd端增加檢測腳本

配置權限

#tail /etc/sudoers

zabbix ALL=(root) NOPASSWD:/usr/local/zabbix/scripts/RaidCheck.py

• 重啟zabbix_agentd

zabbix_server端，通過zabbix_get -s *** -k raid.phy.discovery

可以獲取到對應機器的硬盤信息
