pyVmomi - vmware api - 可用于zabbix监控

介绍

1. vmware的官方python sdk类型项目，可以通过此sdk简单实现以api的方式接入到vcenter来操作vmware集群（就是说此sdk实际上是以api的形式接入到vcenter的）

安装pyvmomi

pip install pyVmomi # 默认会安装最新版本的pyVmomi

 

登录到vcenter的例子

# 登录信息部分

host = 'your vcenter ip address'

user = 'user'

pwd = 'password'

port = 443



# 代码主体

try:

# 登录到vcenter,这里使用NoSSL验证，直接使用SmartConnect的话会报错

service_instance = connect.SmartConnectNoSSL(host=host,

user=user,

pwd=pwd,

port=port)

例子

查看vmware集群所有存储的总容量和剩余空间（这里通过代码判断排除了ESXi的本地存储）

需要真正给Zabbix用的监控脚本 和 Zabbix监控模板（监控所有共享存储的总容量 和 每个共享存储的容量），可与我联系
