Zabbix采集dell存储硬件性能数据

背景

客户物理服务器的备份解决方案使用Veritas，Veritas服务器挂载本地Storage作为备份存储。

1. 由于zabbix官网上没找到对应型号的dell storage监控模版，测试默认snmp模版未能正常采集出需求数据，随查询Storage官网有对外api接口，通过api接口获取需求数据。

2. San Switch官网找到的监控模版只能采集CPU、内存无法采集端口流量及端口(UP、Down)状态。通过SNMP MIB找到对应OID手动添加监控项采集出对应数据。

部署架构

采集Storage数据

存储健康状态
总存储空间
存储空间利用率
存储池IOPS及读写速度
