Zabbix监控硬盘状态
##通过zabbix监控机房硬盘状态，减少跑机房次数，提前进行硬盘故障预警。
#亲测可以使用的脚本
准备包
megacli-8.02.21-1-mdv2012.0.x86_64.rpm
通过salt直接安装到每台服务器
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端增加检测脚本

配置权限
#tail /etc/sudoers
zabbix ALL=(root) NOPASSWD:/usr/local/zabbix/scripts/RaidCheck.py
重启zabbix_agentd
zabbix_server端，通过zabbix_get -s *** -k raid.phy.discovery
可以获取到对应机器的硬盘信息
