Azure经典虚拟机（Windows）如何监测单个磁盘的使用空间

 

Azure云平台创建经典虚拟机（Windows）后，发现仪表板的监测项下默认是没有针对磁盘空间进行检测的指标的

 

本地机器安装Windows Azure Powershell模块，并通过如下命令登陆并查看到默认的诊断扩展是没有Disk Free Space参数的

Add-AzureAccount -Environment AzureChinaCloud
$vm = Get-AzureVM -ServiceName hlmcloudsn1-*** -Name hlmwin12n1-***
$PublicConfiguration = (Get-AzureVMDiagnosticsExtension -VM $vm).PublicConfiguration
$encodedconfig = (ConvertFrom-Json -InputObject $PublicConfiguration).xmlCfg
$xmlconfig = [System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String($encodedconfig))
Write-Host $xmlconfig

 

参考Azure官网（https://docs.microsoft.com/zh-cn/azure/virtual-machines/extensions/diagnostics-windows#sample-diagnostics-configuration）说明，了解到可以对诊断扩展的参数进行自定义，因此在原有的配置文件中加入针对单块盘的指控指标即可对单块磁盘的使用量进行检测，编辑后的配置文件见下（标黄内容为新添加的内容，需要根据实际环境进行替换）

使用如下命令，跟新诊断扩展（将如上文件保存为DiagnosticsPubConfig.xml文件）

$vm = Get-AzureVM -ServiceName hlmcloudsn1-*** -Name hlmwin12n1-***$Config_Path = "C:\Users\he.liming\Desktop\DiagnosticsPubConfig.xml"
$Storage_Context = New-AzureStorageContext -StorageAccountName "hlmston1t2***" -StorageAccountKey "qlIs3Oc9vPqpkCQsf9Lk6oqKfbHbrPUNz3xNqm9VgcUPug8U7XfX***"
$vm_Update = Set-AzureVMDiagnosticsExtension -DiagnosticsConfigurationPath $Config_Path -VM $vm -StorageContext $Storage_Context
Update-AzureVM -ServiceName hlmcloudsn1-*** -Name hlmwin12n1-*** -VM $vm_Update.VM

 

查看虚拟机的仪表板，发现已经可以查看自定义的盘符分区大小了
