项目
11/06/2024

了解使用 Azure 资源图表进行查询的第一步是对查询语言有基本的了解。如果还不熟悉 Azure 数据资源管理器，建议查看基础知识，以了解如何撰写所需资源的请求。

我们将逐步介绍以下高级查询：

显示每个资源类型的 API 版本
获取虚拟机规模集容量和大小
删除结果中的列
列出所有标记名称
由正则表达式匹配的虚拟机
列出具有特定写入位置的 Azure Cosmos DB
具有订阅名称的密钥保管库
列出 SQL 数据库及其弹性池
列出其网络接口和公共 IP 的虚拟机
列出虚拟机上安装的所有扩展
在资源组中查找具有特定标记的存储帐户
将两个查询的结果合并为单个结果
获取网络接口的虚拟网络和子网
按电源状态扩展属性汇总虚拟机

如果没有 Azure 订阅，请在开始之前创建一个免费帐户。

语言支持

Azure CLI（通过扩展）和 Azure PowerShell（通过模块）支持 Azure 资源图表。在运行以下任何查询之前，请检查环境是否已准备就绪。有关安装和验证所选 shell 环境的步骤，请参阅 Azure CLI 和 Azure PowerShell。

显示每个资源类型的 API 版本

在更新过程中，Resource Graph 主要使用资源提供程序 API 的最新非预览版来 GET 资源属性。在某些情况下，会覆盖所使用的 API 版本，以便在结果中提供更多当前或广泛使用的属性。以下查询详述了用于在每个资源类型上收集属性的 API 版本：

Resources
| distinct type, apiVersion
| where isnotnull(apiVersion)
| order by type asc

az graph query -q "Resources | distinct type, apiVersion | where isnotnull(apiVersion) | order by type asc"

Search-AzGraph -Query "Resources | distinct type, apiVersion | where isnotnull(apiVersion) | order by type asc"

获取虚拟机规模集容量和大小

此查询将查找虚拟机规模集资源，并获取各种详细信息，包括规模集的虚拟机大小和容量。此查询使用 toint() 函数将容量强制转换为数字以供排序。最后会将列重命名为自定义命名属性。

Resources
| where type=~ 'microsoft.compute/virtualmachinescalesets'
| where name contains 'contoso'
| project subscriptionId, name, location, resourceGroup, Capacity = toint(sku.capacity), Tier = sku.name
| order by Capacity desc

az graph query -q "Resources | where type=~ 'microsoft.compute/virtualmachinescalesets' | where name contains 'contoso' | project subscriptionId, name, location, resourceGroup, Capacity = toint(sku.capacity), Tier = sku.name | order by Capacity desc"

Search-AzGraph -Query "Resources | where type=~ 'microsoft.compute/virtualmachinescalesets' | where name contains 'contoso' | project subscriptionId, name, location, resourceGroup, Capacity = toint(sku.capacity), Tier = sku.name | order by Capacity desc"

删除结果中的列

以下查询使用 summarize 按订阅对资源进行计数，使用 join 将其与 ResourceContainers 表中的订阅详细信息合并，然后使用 project-away 删除某些列。

Resources
| summarize resourceCount=count() by subscriptionId
| join (ResourceContainers | where type=='microsoft.resources/subscriptions' | project SubName=name, subscriptionId) on subscriptionId
| project-away subscriptionId, subscriptionId1

az graph query -q "Resources | summarize resourceCount=count() by subscriptionId | join (ResourceContainers | where type=='microsoft.resources/subscriptions' | project SubName=name, subscriptionId) on subscriptionId| project-away subscriptionId, subscriptionId1"

Search-AzGraph -Query "Resources | summarize resourceCount=count() by subscriptionId | join (ResourceContainers | where type=='microsoft.resources/subscriptions' | project SubName=name, subscriptionId) on subscriptionId| project-away subscriptionId, subscriptionId1"

列出所有标记名称

此查询以标记开头，并生成一个 JSON 对象，列出所有唯一标记名称及其对应的类型。

Resources
| project tags
| summarize buildschema(tags)

az graph query -q "Resources | project tags | summarize buildschema(tags)"

Search-AzGraph -Query "Resources | project tags | summarize buildschema(tags)"

由正则表达式匹配的虚拟机

此查询查找与某个正则表达式（称为 regex）匹配的虚拟机。可以使用 matches regex @ 定义要匹配的正则表达式，即 ^Contoso(.*)[0-9]+$。该 regex 定义说明如下：

^ - 匹配项必须以该字符串的开头开头。
Contoso - 区分大小写的字符串。
(.*) - 子表达式匹配项：
- . - 匹配任何单一字符（换行符除外）。
- * - 匹配上一个元素零次或多次。
[0-9] - 数字 0 到 9 的字符组匹配项。
+ - 匹配上一个元素一次或多次。
$ - 上一个元素的匹配项必须出现在该字符串的末尾。

按名称进行匹配后，查询将对名称进行投影并按名称升序排序。

Resources
| where type =~ 'microsoft.compute/virtualmachines' and name matches regex @'^Contoso(.*)[0-9]+$'
| project name
| order by name asc

az graph query -q "Resources | where type =~ 'microsoft.compute/virtualmachines' and name matches regex @'^Contoso(.*)[0-9]+\$' | project name | order by name asc"

Search-AzGraph -Query "Resources | where type =~ 'microsoft.compute/virtualmachines' and name matches regex @'^Contoso(.*)[0-9]+$' | project name | order by name asc"

列出具有特定写入位置的 Azure Cosmos DB

以下查询限制了 Azure Cosmos DB 资源，使用 mv-expand 展开 properties.writeLocations 的属性包，然后投影特定字段，并将结果进一步限制为与“美国东部”或“美国西部”匹配的 properties.writeLocations.locationName 值。

Resources
| where type =~ 'microsoft.documentdb/databaseaccounts'
| project id, name, writeLocations = (properties.writeLocations)
| mv-expand writeLocations
| project id, name, writeLocation = tostring(writeLocations.locationName)
| where writeLocation in ('East US', 'West US')
| summarize by id, name

az graph query -q "Resources | where type =~ 'microsoft.documentdb/databaseaccounts' | project id, name, writeLocations = (properties.writeLocations) | mv-expand writeLocations | project id, name, writeLocation = tostring(writeLocations.locationName) | where writeLocation in ('East US', 'West US') | summarize by id, name"

Search-AzGraph -Query "Resources | where type =~ 'microsoft.documentdb/databaseaccounts' | project id, name, writeLocations = (properties.writeLocations) | mv-expand writeLocations | project id, name, writeLocation = tostring(writeLocations.locationName) | where writeLocation in ('East US', 'West US') | summarize by id, name"

具有订阅名称的密钥保管库

以下查询演示了 join（“类型”为“leftouter”）的复杂用法。查询将联接表限制为订阅资源并具有 project，以仅包括原始字段 SubscriptionId 和重命名为 SubName 的 name 字段。字段重命名避免了 join 将其添加为 name1，因为该字段已存在于资源中。原始表使用 where 进行筛选，以下 project 包括两个表中的列。查询结果是所有密钥保管库，其中显示密钥保管库的类型、名称以及其所在订阅的名称。

Resources
| join kind=leftouter (ResourceContainers | where type=='microsoft.resources/subscriptions' | project SubName=name, subscriptionId) on subscriptionId
| where type == 'microsoft.keyvault/vaults'
| project type, name, SubName

az graph query -q "Resources | join kind=leftouter (ResourceContainers | where type=='microsoft.resources/subscriptions' | project SubName=name, subscriptionId) on subscriptionId | where type == 'microsoft.keyvault/vaults' | project type, name, SubName"

Search-AzGraph -Query "Resources | join kind=leftouter (ResourceContainers | where type=='microsoft.resources/subscriptions' | project SubName=name, subscriptionId) on subscriptionId | where type == 'microsoft.keyvault/vaults' | project type, name, SubName"

列出 SQL 数据库及其弹性池

以下查询使用 leftouter join 将 SQL 数据库资源及其相关弹性池组合在一起（如果有）。

Resources
| where type =~ 'microsoft.sql/servers/databases'
| project databaseId = id, databaseName = name, elasticPoolId = tolower(tostring(properties.elasticPoolId))
| join kind=leftouter (
    Resources
    | where type =~ 'microsoft.sql/servers/elasticpools'
    | project elasticPoolId = tolower(id), elasticPoolName = name, elasticPoolState = properties.state)
on elasticPoolId
| project-away elasticPoolId1

az graph query -q "Resources | where type =~ 'microsoft.sql/servers/databases' | project databaseId = id, databaseName = name, elasticPoolId = tolower(tostring(properties.elasticPoolId)) | join kind=leftouter ( Resources | where type =~ 'microsoft.sql/servers/elasticpools' | project elasticPoolId = tolower(id), elasticPoolName = name, elasticPoolState = properties.state) on elasticPoolId | project-away elasticPoolId1"

Search-AzGraph -Query "Resources | where type =~ 'microsoft.sql/servers/databases' | project databaseId = id, databaseName = name, elasticPoolId = tolower(tostring(properties.elasticPoolId)) | join kind=leftouter ( Resources | where type =~ 'microsoft.sql/servers/elasticpools' | project elasticPoolId = tolower(id), elasticPoolName = name, elasticPoolState = properties.state) on elasticPoolId | project-away elasticPoolId1"

列出具有其网络接口和公共 IP 的虚拟机

此查询使用两个 leftouter join 命令将使用资源管理器部署模型创建的虚拟机、其相关网络接口以及与这些网络接口相关的任何公共 IP 地址组合在一起。

Resources
| where type =~ 'microsoft.compute/virtualmachines'
| extend nics=array_length(properties.networkProfile.networkInterfaces)
| mv-expand nic=properties.networkProfile.networkInterfaces
| where nics == 1 or nic.properties.primary =~ 'true' or isempty(nic)
| project vmId = id, vmName = name, vmSize=tostring(properties.hardwareProfile.vmSize), nicId = tostring(nic.id)
| join kind=leftouter (
    Resources
    | where type =~ 'microsoft.network/networkinterfaces'
    | extend ipConfigsCount=array_length(properties.ipConfigurations)
    | mv-expand ipconfig=properties.ipConfigurations
    | where ipConfigsCount == 1 or ipconfig.properties.primary =~ 'true'
    | project nicId = id, publicIpId = tostring(ipconfig.properties.publicIPAddress.id))
on nicId
| project-away nicId1
| summarize by vmId, vmName, vmSize, nicId, publicIpId
| join kind=leftouter (
    Resources
    | where type =~ 'microsoft.network/publicipaddresses'
    | project publicIpId = id, publicIpAddress = properties.ipAddress)
on publicIpId
| project-away publicIpId1

az graph query -q "Resources | where type =~ 'microsoft.compute/virtualmachines' | extend nics=array_length(properties.networkProfile.networkInterfaces) | mv-expand nic=properties.networkProfile.networkInterfaces | where nics == 1 or nic.properties.primary =~ 'true' or isempty(nic) | project vmId = id, vmName = name, vmSize=tostring(properties.hardwareProfile.vmSize), nicId = tostring(nic.id) | join kind=leftouter ( Resources | where type =~ 'microsoft.network/networkinterfaces' | extend ipConfigsCount=array_length(properties.ipConfigurations) | mv-expand ipconfig=properties.ipConfigurations | where ipConfigsCount == 1 or ipconfig.properties.primary =~ 'true' | project nicId = id, publicIpId = tostring(ipconfig.properties.publicIPAddress.id)) on nicId | project-away nicId1 | summarize by vmId, vmName, vmSize, nicId, publicIpId | join kind=leftouter ( Resources | where type =~ 'microsoft.network/publicipaddresses' | project publicIpId = id, publicIpAddress = properties.ipAddress) on publicIpId | project-away publicIpId1"

Search-AzGraph -Query "Resources | where type =~ 'microsoft.compute/virtualmachines' | extend nics=array_length(properties.networkProfile.networkInterfaces) | mv-expand nic=properties.networkProfile.networkInterfaces | where nics == 1 or nic.properties.primary =~ 'true' or isempty(nic) | project vmId = id, vmName = name, vmSize=tostring(properties.hardwareProfile.vmSize), nicId = tostring(nic.id) | join kind=leftouter ( Resources | where type =~ 'microsoft.network/networkinterfaces' | extend ipConfigsCount=array_length(properties.ipConfigurations) | mv-expand ipconfig=properties.ipConfigurations | where ipConfigsCount == 1 or ipconfig.properties.primary =~ 'true' | project nicId = id, publicIpId = tostring(ipconfig.properties.publicIPAddress.id)) on nicId | project-away nicId1 | summarize by vmId, vmName, vmSize, nicId, publicIpId | join kind=leftouter ( Resources | where type =~ 'microsoft.network/publicipaddresses' | project publicIpId = id, publicIpAddress = properties.ipAddress) on publicIpId | project-away publicIpId1"

列出虚拟机上安装的所有扩展

首先，此查询针对虚拟机资源类型使用 extend 以获取大写的 (toupper()) ID、获取操作系统名称和类型，以及获取虚拟机大小。获取大写的资源 ID 是准备联接另一个属性的好方法。然后，此查询将 join 用于为 leftouter 的 kind，通过匹配扩展 ID 的大写 substring 来获取虚拟机扩展。 “/extensions/<ExtensionName>”之前的 ID 部分与虚拟机 ID 的格式相同，因此我们将此属性用于 join。然后会针对虚拟机扩展的名称将 summarize 用于 make_list 以合并每个扩展的名称，其中 id、OSName、OSType和 VMSize 在单个数组属性中是相同的。最后，我们通过 asc 对小写的 OSName 进行 order by 操作。默认情况下，order by 为降序。

Resources
| where type == 'microsoft.compute/virtualmachines'
| extend
    JoinID = toupper(id),
    OSName = tostring(properties.osProfile.computerName),
    OSType = tostring(properties.storageProfile.osDisk.osType),
    VMSize = tostring(properties.hardwareProfile.vmSize)
| join kind=leftouter(
    Resources
    | where type == 'microsoft.compute/virtualmachines/extensions'
    | extend
        VMId = toupper(substring(id, 0, indexof(id, '/extensions'))),
        ExtensionName = name
) on $left.JoinID == $right.VMId
| summarize Extensions = make_list(ExtensionName) by id, OSName, OSType, VMSize
| order by tolower(OSName) asc

az graph query -q "Resources | where type == 'microsoft.compute/virtualmachines' | extend JoinID = toupper(id), OSName = tostring(properties.osProfile.computerName), OSType = tostring(properties.storageProfile.osDisk.osType), VMSize = tostring(properties.hardwareProfile.vmSize) | join kind=leftouter( Resources | where type == 'microsoft.compute/virtualmachines/extensions' | extend VMId = toupper(substring(id, 0, indexof(id, '/extensions'))), ExtensionName = name ) on \$left.JoinID == \$right.VMId | summarize Extensions = make_list(ExtensionName) by id, OSName, OSType, VMSize | order by tolower(OSName) asc"

Search-AzGraph -Query "Resources | where type == 'microsoft.compute/virtualmachines' | extend JoinID = toupper(id), OSName = tostring(properties.osProfile.computerName), OSType = tostring(properties.storageProfile.osDisk.osType), VMSize = tostring(properties.hardwareProfile.vmSize) | join kind=leftouter( Resources | where type == 'microsoft.compute/virtualmachines/extensions' | extend VMId = toupper(substring(id, 0, indexof(id, '/extensions'))), ExtensionName = name ) on `$left.JoinID == `$right.VMId | summarize Extensions = make_list(ExtensionName) by id, OSName, OSType, VMSize | order by tolower(OSName) asc"

在资源组上查找具有特定标记的存储帐户

以下查询使用 inner join 将存储帐户连接到具有指定标记名称和标记值（区分大小写）的资源组。

Resources
| where type =~ 'microsoft.storage/storageaccounts'
| join kind=inner (
    ResourceContainers
    | where type =~ 'microsoft.resources/subscriptions/resourcegroups'
    | where tags['Key1'] =~ 'Value1'
    | project subscriptionId, resourceGroup)
on subscriptionId, resourceGroup
| project-away subscriptionId1, resourceGroup1

az graph query -q "Resources | where type =~ 'microsoft.storage/storageaccounts' | join kind=inner ( ResourceContainers | where type =~ 'microsoft.resources/subscriptions/resourcegroups' | where tags['Key1'] =~ 'Value1' | project subscriptionId, resourceGroup) on subscriptionId, resourceGroup | project-away subscriptionId1, resourceGroup1"

Search-AzGraph -Query "Resources | where type =~ 'microsoft.storage/storageaccounts' | join kind=inner ( ResourceContainers | where type =~ 'microsoft.resources/subscriptions/resourcegroups' | where tags['Key1'] =~ 'Value1' | project subscriptionId, resourceGroup) on subscriptionId, resourceGroup | project-away subscriptionId1, resourceGroup1"

如果必须查找不区分大小写的标记名称和标记值，请将 mv-expand 与 bagexpansion 参数配合使用。此查询使用的配额高于前一查询，因此只在必要的时候使用 mv-expand。

Resources
| where type =~ 'microsoft.storage/storageaccounts'
| join kind=inner (
    ResourceContainers
    | where type =~ 'microsoft.resources/subscriptions/resourcegroups'
    | mv-expand bagexpansion=array tags
    | where isnotempty(tags)
    | where tags[0] =~ 'key1' and tags[1] =~ 'value1'
    | project subscriptionId, resourceGroup)
on subscriptionId, resourceGroup
| project-away subscriptionId1, resourceGroup1

az graph query -q "Resources | where type =~ 'microsoft.storage/storageaccounts' | join kind=inner ( ResourceContainers | where type =~ 'microsoft.resources/subscriptions/resourcegroups' | mv-expand bagexpansion=array tags | where isnotempty(tags) | where tags[0] =~ 'key1' and tags[1] =~ 'value1' | project subscriptionId, resourceGroup) on subscriptionId, resourceGroup | project-away subscriptionId1, resourceGroup1"

Search-AzGraph -Query "Resources | where type =~ 'microsoft.storage/storageaccounts' | join kind=inner ( ResourceContainers | where type =~ 'microsoft.resources/subscriptions/resourcegroups' | mv-expand bagexpansion=array tags | where isnotempty(tags) | where tags[0] =~ 'key1' and tags[1] =~ 'value1' | project subscriptionId, resourceGroup) on subscriptionId, resourceGroup | project-away subscriptionId1, resourceGroup1"

将两个查询的结果合并为单个结果

以下查询使用 union 从 ResourceContainers 表中获取结果，并将它们添加到 Resources 表中的结果。

ResourceContainers
| where type=='microsoft.resources/subscriptions/resourcegroups' | project name, type  | limit 5
| union  (Resources | project name, type | limit 5)

az graph query -q "ResourceContainers | where type=='microsoft.resources/subscriptions/resourcegroups' | project name, type  | limit 5 | union  (Resources | project name, type | limit 5)"

Search-AzGraph -Query "ResourceContainers | where type=='microsoft.resources/subscriptions/resourcegroups' | project name, type  | limit 5 | union  (Resources | project name, type | limit 5)"

获取网络接口的虚拟网络和子网

使用正则表达式 parse 从资源 ID 属性中获取虚拟网络和子网名称。虽然 parse 支持从复杂字段获取数据，但如果属性存在，则最好直接访问属性，而不是使用 parse。

Resources
| where type =~ 'microsoft.network/networkinterfaces'
| project id, ipConfigurations = properties.ipConfigurations
| mvexpand ipConfigurations
| project id, subnetId = tostring(ipConfigurations.properties.subnet.id)
| parse kind=regex subnetId with '/virtualNetworks/' virtualNetwork '/subnets/' subnet
| project id, virtualNetwork, subnet

az graph query -q "Resources | where type =~ 'microsoft.network/networkinterfaces' | project id, ipConfigurations = properties.ipConfigurations | mvexpand ipConfigurations | project id, subnetId = tostring(ipConfigurations.properties.subnet.id) | parse kind=regex subnetId with '/virtualNetworks/' virtualNetwork '/subnets/' subnet | project id, virtualNetwork, subnet"

Search-AzGraph -Query "Resources | where type =~ 'microsoft.network/networkinterfaces' | project id, ipConfigurations = properties.ipConfigurations | mvexpand ipConfigurations | project id, subnetId = tostring(ipConfigurations.properties.subnet.id) | parse kind=regex subnetId with '/virtualNetworks/' virtualNetwork '/subnets/' subnet | project id, virtualNetwork, subnet"

按电源状态扩展属性汇总虚拟机

此查询使用虚拟机上的扩展属性按电源状态进行汇总。

Resources
| where type == 'microsoft.compute/virtualmachines'
| summarize count() by tostring(properties.extended.instanceView.powerState.code)

az graph query -q "Resources | where type == 'microsoft.compute/virtualmachines' | summarize count() by tostring(properties.extended.instanceView.powerState.code)"

Search-AzGraph -Query "Resources | where type == 'microsoft.compute/virtualmachines' | summarize count() by tostring(properties.extended.instanceView.powerState.code)"
