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）
   
   

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
