如何对ARM下的VM批量加Diag
Diag其实就是VM的一个Extension，
主要作用是在Portal上展示VM相关的信息指标，例如：CPU, IO, Net等相关信息。
主要是RM架构下VM的一个重要，直观的组件，
创建完VM默认虚拟机是不呈现这些信息，需要配置存储账号后才会展现，
那么，如果我们在页面上对每个虚拟机都这么操作就会执行重复的工作，那么工作就会没什么意义，
powershell就会干这些事，那么我们浅谈下如何执行这些工作。
首先，需要在powershell的活动目录放下一个 diagnostics_publicconfig.xml的文件，
这个XML文件里就包括我们需要开启的指标信息，详细我们可以自定义选择。

编辑完之后，那么我们在powershell执行以下代码就可以了。
Note：如果是单台虚拟机请指定存储账号和去掉foreach的循环。
具体可以改下代码的逻辑。
1 $VMs = Get-AzureRmVM 2 foreach ($vm in $VMs){ 3 $rg = $vm.ResourceGroupName #资源组名称 4 $vmName = $vm.Name #虚拟机名称 5 $storageName = $rg.ToLower() + "diag" #存储帐号名称 6 if($vmName -like "CNBJCAP00**" ){ 7 $vm = Get-AzureRmVM -ResourceGroupName $rg -Name $vmName 8 $storage = Get-AzureRmStorageAccount -ResourceGroupName $rg -Name $storageName 9 $storagekey = (Get-AzureRmStorageAccountKey -ResourceGroupName $rg -Name $storageName).Value[0] 10 $vmName+"这台虚拟机在名单中正在加监控请稍等" 11 Set-AzureRmVMDiagnosticsExtension -ResourceGroupName $rg ` 12 -VMName $vmName ` 13 -StorageAccountName $storageName ` 14 -StorageAccountKey $storagekey ` 15 -DiagnosticsConfigurationPath "diagnostics_publicconfig.xml" 16 continue; 17 } 18 else{ 19 $vmName+"这台虚拟机不符合要求将被剔除"; 20 } 21 }
