perl 获取虚拟机信息

[root@master ~]# cat simple_flow.pl

! /usr/bin/perl -w

use strict;

use warnings;

导入 vSphere SDK for Perl 的运行支持模块

此模块用来完成服务器端 - 客户端数据映射、载入客户端和服务器端之间的交互函数等

use VMware::VIRuntime;

hash 结构 %opts 存放自定义命令行参数

my %opts =( 
entity => { 
type => “=s”, 
variable => “VI_ENTITY”, 
help => “ManagedEntity type: HostSystem, etc”, 
required => 1, 
}, 
);

vSphere SDK for Perl 为所有脚本提供了一些基本的命令行参数，如 –server，–url 等

Opts::add_options 方法用以添加用户自定义参数

Opts::add_options(%opts);

解析命令行参数

Opts::parse();

验证命令行参数

Opts::validate();

连接远程服务器，vCenter 或 ESX server

Util::connect();

提取命令行参数 entity 的值

my $entity_type = Opts::get_option(‘entity’);

根据 entity 值查询服务器端对象，

Vim::find_entity_views 返回服务器端对象对应的 Perl 视图

my entityviews=Vim::findentityviews(viewtype=>entity_type);

输出服务器端对象 Perl 视图的信息，如类型和名称等

foreach my entityview(@entity_views) { 
my entityname=entity_view->name; 
Util::trace(0, “Found entitytype:entity_name
”); 
}

断开与远程服务器的连接

Util::disconnect();
