【Azure Developer】使用Azure Resource Graph的查询语法的示例

文章“【Azure Developer】在Azure Resource Graph Explorer中查看当前订阅下的所有资源信息列表并导出（如VM的名称，IP地址内网/公网，OS,区域等) ”的另一个示例。

问题描述

使用Azure Resource Graph查询：把这订阅(Subscription ID)下的VM虚拟机和相关磁盘信息拉取一下数据（VM名字，VM的tag，VM的资源ID，硬盘名字，硬盘大小，磁盘的资源ID)

问题答案

根据Azure Resource Graph Explorer中提供的Resources表来查看VM的相关信息。而磁盘相关的信息处于 properties.storageProfile.osDisk 以及 properties.storageProfile.dataDisks中。

示例查询语句为：

resources
| where type =~ 'microsoft.compute/virtualmachines'
| extend  osDisk = properties.storageProfile.osDisk, disks = properties.storageProfile.dataDisks
| project  name, tags, id, osDisk.name, osDisk.diskSizeGB, osDisk.managedDisk.id,
disks[0].name, disks[0].diskSizeGB,
disks[1].managedDisk.id, disks[1].name, disks[1].diskSizeGB, disks[1].managedDisk.id,
disks[2].name, disks[2].diskSizeGB,disks[2].managedDisk.id

查询结果示例：

附录一：新创建的VM如果时托管类的Disk，则Disk Size信息无法直接在Type == ‘microsoft.compute/virtualmachines’ 中获取到，需要在 type=='microsoft.compute/disks'  资源中关联出来。

参考示例

Resources
| where type == "microsoft.compute/virtualmachines"
| extend os = properties.storageProfile.imageReference.offer
| extend sku = properties.storageProfile.imageReference.sku
| extend hostName = properties.osProfile.computerName
| extend vmSize = properties.hardwareProfile.vmSize
| extend osDiskName = properties.storageProfile.osDisk.name
| extend osDiskSize = properties.storageProfile.osDisk.diskSizeGB
| extend dataDisks = properties.storageProfile.dataDisks
| extend managedDiskId_0= tolower(tostring(dataDisks[0].managedDisk.id))
| extend managedDiskId_1 = tolower(tostring(dataDisks[1].managedDisk.id))
| join kind=leftouter (
    Resources
    | where type == 'microsoft.compute/disks'
    | project managedDiskId_0 = tolower(id),dataDisk_0_Name=name,dataDisk_0_SizeGB=properties.diskSizeGB)
on managedDiskId_0
| join kind=leftouter (
    Resources
    | where type == 'microsoft.compute/disks'
    | project managedDiskId_1 = tolower(id),dataDisk_1_Name=name,dataDisk_1_SizeGB=properties.diskSizeGB)
on managedDiskId_1
| project subscriptionId, vmName = name, resourceGroup, location, hostName, os, sku, osDiskName, osDiskSize, vmSize,  dataDisks,
managedDiskId_0, dataDisks[0].name, dataDisk_0_diskSizeGB=iif(isnull(dataDisks[0].diskSizeGB),dataDisk_0_SizeGB,dataDisks[0].diskSizeGB),
managedDiskId_1, dataDisks[1].name, dataDisk_1_diskSizeGB=iif(isnull(dataDisks[1].diskSizeGB),dataDisk_1_SizeGB,dataDisks[1].diskSizeGB),
properties
