虚拟化前端
通过采集器采集vmware的数据到mongodb数据库，在通过前端进行展示及显示。
虚拟机，存储，节点之间的关联
虚拟机实例Instance UUID,磁盘uuid，以及esxi节点的IP来确定。每个信息之间都会打一个tag标签。标签也是独一无二。标签的作用是为后期采集性能信息使用。
该脚本功能主要是采集vmwre的虚拟机，存储，及节点的信息。

目前这个采集主要是为我的备份数据整理而生，目前虚拟化有2000多台，有3套备份系统，需要根据虚拟机的特性，使用哪套备份系统。
通过选择及筛选
通过指定虚拟机的备份厂商，给每个厂商建立一个账号，可以查询自己需要备份哪些虚拟机，备份成功后打上成功的标签。之后有空我会对接3套备份系统的数据库，通过自动化来处理是否成功备份。
查看存储信息
由于虚拟化节点太多，通过该界面，可以快速查看存储相关信息，抽空会写一个告警管理，对剩余容量太少的进行告警。
存储相关信息
查看节点信息
有空写个详细的，这个比较简单。
