Count of virtual machines by availability state and Subscription ID

Returns the count of virtual machines (type Microsoft.Compute/virtualMachines) aggregated by their availability state across each of your subscriptions.

HealthResources
| where type =~ 'microsoft.resourcehealth/availabilitystatuses'
| summarize count() by subscriptionId, AvailabilityState = tostring(properties.availabilityState)

az graph query -q "HealthResources | where type =~ 'microsoft.resourcehealth/availabilitystatuses' | summarize count() by subscriptionId, AvailabilityState = tostring(properties.availabilityState)"

Search-AzGraph -Query "HealthResources | where type =~ 'microsoft.resourcehealth/availabilitystatuses' | summarize count() by subscriptionId, AvailabilityState = tostring(properties.availabilityState)"

Count of virtual machines by power state

Returns count of virtual machines (type Microsoft.Compute/virtualMachines) categorized according to their power state. For more information on power states, see Power states overview.

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

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

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

Count virtual machines by OS type

Building on the previous query, we're still limiting by Azure resources of type Microsoft.Compute/virtualMachines, but are no longer limiting the number of records returned. Instead, we used summarize and count() to define how to group and aggregate the values by property, which in this example is properties.storageProfile.osDisk.osType. For an example of how this string looks in the full object, see explore resources - virtual machine discovery.

Resources
| where type =~ 'Microsoft.Compute/virtualMachines'
| summarize count() by tostring(properties.storageProfile.osDisk.osType)

az graph query -q "Resources | where type =~ 'Microsoft.Compute/virtualMachines' | summarize count() by tostring(properties.storageProfile.osDisk.osType)"

Search-AzGraph -Query "Resources | where type =~ 'Microsoft.Compute/virtualMachines' | summarize count() by tostring(properties.storageProfile.osDisk.osType)"

Count virtual machines by OS type with extend

A different way to write the 'Count virtual machines by OS type' query is to extend a property and give it a temporary name for use within the query, in this case os. os is then used by summarize and count() as in the referenced example.

Resources
| where type =~ 'Microsoft.Compute/virtualMachines'
| extend os = properties.storageProfile.osDisk.osType
| summarize count() by tostring(os)

az graph query -q "Resources | where type =~ 'Microsoft.Compute/virtualMachines' | extend os = properties.storageProfile.osDisk.osType | summarize count() by tostring(os)"

Search-AzGraph -Query "Resources | where type =~ 'Microsoft.Compute/virtualMachines' | extend os = properties.storageProfile.osDisk.osType | summarize count() by tostring(os)"

Get all New alerts from the past 30 days

This query provides a list of all the user's New alerts, from the past 30 days.

iotsecurityresources
| where type == 'microsoft.iotsecurity/locations/devicegroups/alerts'
| where todatetime(properties.startTimeUtc) > ago(30d) and properties.status == 'New'

az graph query -q "iotsecurityresources | where type == 'microsoft.iotsecurity/locations/devicegroups/alerts' | where todatetime(properties.startTimeUtc) > ago(30d) and properties.status == 'New'"

Search-AzGraph -Query "iotsecurityresources | where type == 'microsoft.iotsecurity/locations/devicegroups/alerts' | where todatetime(properties.startTimeUtc) > ago(30d) and properties.status == 'New'"

Get virtual machine scale set capacity and size

This query looks for virtual machine scale set resources and gets various details including the virtual machine size and the capacity of the scale set. The query uses the toint() function to cast the capacity to a number so that it can be sorted. Finally, the columns are renamed into custom named properties.

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"

List all extensions installed on a virtual machine

First, this query uses extend on the virtual machines resource type to get the ID in uppercase (toupper()) the ID, get the operating system name and type, and get the virtual machine size. Getting the resource ID in uppercase is a good way to prepare to join to another property. Then, the query uses join with kind as leftouter to get virtual machine extensions by matching an uppercase substring of the extension ID. The portion of the ID before /extensions/\<ExtensionName\> is the same format as the virtual machines ID, so we use this property for the join. summarize is then used with make_list on the name of the virtual machine extension to combine the name of each extension where ID, OSName, OSType, and VMSize are the same into a single array property. Lastly, we order by lowercase OSName with asc. By default, order by is descending.

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"

Show all virtual machines ordered by name in descending order

To list only virtual machines (which are type Microsoft.Compute/virtualMachines), we can match the property type in the results. Similar to the previous query, desc changes the order by to be descending. The =~ in the type match tells Resource Graph to be case insensitive.

Resources
| project name, location, type
| where type =~ 'Microsoft.Compute/virtualMachines'
| order by name desc

az graph query -q "Resources | project name, location, type | where type =~ 'Microsoft.Compute/virtualMachines' | order by name desc"

Search-AzGraph -Query "Resources | project name, location, type | where type =~ 'Microsoft.Compute/virtualMachines' | order by name desc"

Show first five virtual machines by name and their OS type

This query uses top to only retrieve five matching records that are ordered by name. The type of the Azure resource is Microsoft.Compute/virtualMachines. project tells Azure Resource Graph which properties to include.

Resources
| where type =~ 'Microsoft.Compute/virtualMachines'
| project name, properties.storageProfile.osDisk.osType
| top 5 by name desc

az graph query -q "Resources | where type =~ 'Microsoft.Compute/virtualMachines' | project name, properties.storageProfile.osDisk.osType | top 5 by name desc"

Search-AzGraph -Query "Resources | where type =~ 'Microsoft.Compute/virtualMachines' | project name, properties.storageProfile.osDisk.osType | top 5 by name desc"

Summarize virtual machine by the power states extended property

This query uses the extended properties on virtual machines to summarize by power states.

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)"

Virtual machines matched by regex

This query looks for virtual machines that match a regular expression (known as regex). The matches regex @ allows us to define the regex to match, which is ^Contoso(.*)[0-9]+$. That regex definition is explained as:

^ - Match must start at the beginning of the string.
Contoso - The case-sensitive string.
(.*) - A subexpression match:
- . - Matches any single character (except a new line).
- * - Matches previous element zero or more times.
[0-9] - Character group match for numbers 0 through 9.
+ - Matches previous element one or more times.
$ - Match of the previous element must occur at the end of the string.

After matching by name, the query projects the name and orders by name ascending.

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"
