背景：
服务器硬盘故障率比较高，希望通过zabbix监控服务器硬盘状态，公司有不同ILO版本HP服务器。ILO低版本的服务器可以通过snmp获取到硬盘状态信息而ILO高版本服务器因为是高版本阵列卡，不支持snmp读取硬盘数据。
服务器型号：
HP ProLiant DL380 Gen Plus
解决：
snmp+redfish方式对服务器进行监控，redfish获取硬盘信息
Redfish
Redfish 是 DMTF 制定的现代服务器硬件管理标准，基于 RESTful API + JSON + HTTPS，核心是安全、易读、可扩展、跨厂商统一，用于替代传统 IPMI。
1. 核心资源类型（常用路径）
资源类型 路径示例 管理内容
Service Root /redfish/v1 服务入口、版本、能力发现DMTF
Systems（服务器） /redfish/v1/Systems/1 CPU、内存、硬盘、网卡、电源状态、引导、KVM
Chassis（机箱） /redfish/v1/Chassis/1 电源、风扇、温度、传感器、物理状态
Managers（BMC） /redfish/v1/Managers/1 BMC 配置、网络、日志、固件、会话
UpdateService /redfish/v1/UpdateService 固件上传、升级任务、进度查询
AccountService /redfish/v1/AccountService 用户、角色、权限、认证
SessionService /redfish/v1/SessionService 会话创建 / 销毁、Token 管理
LogServices /redfish/v1/Systems/1/LogServices 会话创建 / 销毁、Token 管理
由于产生官方Ipmi和redfish没有详细文档，我们在服务器web管理界面使用F12查看接口请求信息。
以下是具体获取数据脚本
