VMware Vcenter_API
介绍
本文主要通过调用Vcenter_API,获取其中的数据中心，集群，主机，网络，存储，虚拟机信息。开发语言 python
- 使用官方sdk pyvmomi
文档
- 模块：https://github.com/vmware/pyvmomi
- 例子：https://github.com/vmware/pyvmomi-community-samples
安装：
pip install pyvmomi
pip install pyVim自己总结的调用API：
# -*- coding: utf-8 -*-
from pyVim import connect
from pyVmomi import vim
import json
class VcenterApi(object):
”“”
收集Vcenter中数据中心，主机集群，主机，网络，虚拟机，的信息
