If you wish to list all the virtual machines in an Azure subscription, execute the "Get-AzVM" command in an elevated PowerShell window. Q: I tried using the command in listing 29 on a Windows machine, by saving it as a .cmd file, then running that inside a command prompt. I needed to get the machines and public IPs, perfect! 3 very important issues need to be kept in mind, and well discuss each next. At the time of this writing Sep 2020 the referenced article doesnt explicitly tell about this known limitation. One issue Ive run into was the fact that getting the most recent IPs was inconsistent sometimes I would change an IP (be it either private or public) against a VM and ARG would show the result immediately, other times it would take hours for the new IP to show in the result of the ARG query. $myResourceGroup - The name of the resource group that contains the virtual machine. Create a VM - simplified Create a VM configuration Get information about VMs Manage VMs Next steps Applies to: Linux VMs Windows VMs Flexible scale sets This article covers some of the Azure PowerShell commands that you can use to create and manage virtual machines in your Azure subscription. The Get-AzVM command is used to get the lists of Virtual machines or the properties of the Azure Virtual Machines present under your Azure subscription. ForEach ($Subscription in $Subscriptions) { But I did mentioned the problem here. This means when executing queries, the type info is not there in the context.. The downside is that for VMs having more than 1 vmNic there will be multiple rows with the same VM name, which makes things less clear. Example: The below Azure cmdlet will help you to retrieve the lists of Azure Virtual Machines whose name starts with TsInfoVM. Youll see the query itself, pagination settings, http headers, etc, Q: How can I see the list of providers that ARG is using, along with their version?A: Use the Kusto query here https://docs.microsoft.com/en-us/azure/governance/resource-graph/samples/advanced?tabs=azure-cli#apiversion. PS C:\> az vm list -otable. A VM showing with 2 public IP addresses most likely has one of them belonging to a Cloud Service that includes it, A Cloud Service Public IP is reserved for the duration of the VMs lifetime, as explained, x-ms-ratelimit-remaining-tenant-reads: 11995, x-ms-ratelimit-remaining-tenant-resource-requests: 14, Check that you have access to all the Azure subscriptions from the drop-down in the top right. Dont worry if this theoretical part doesnt make a lot of sense right now, because things will become clearer in one of the next sections, where well be building our query from scratch, and see the outcome at each step. "VMOSDisk" = $vm.StorageProfile.OsDisk.Name You could rightly wonder how this is so, and particularly how can multiple public IPs be assigned to the same VM, particularly since a single private IP is allowed. Assuming you have Az Module installed, try: Thanks for contributing an answer to Stack Overflow! Azure CLI itself supports Azure Resource Graph (ARG) just fine through the az graph command. To rewrite the query and enable paging, see the docs for an example:https://aka.ms/arg-results-truncated. There are 2 concerns: consistency and skip functionality, and neither works as expected when the id is missing. } Unfortunately this only returns the VMs listed under Virtual machines (classic). New-Object psobject -Property @{ The output CSV file will contain multiple IP addresses separated by space, just as the ARG Powershell code weve seen before. "VMProvisioningState" = $vm.ProvisioningState Before you deep in, make sure you have right privillage to login via Azure portal, Azure CLI or AzureRM module install on your local machine to run this script in powershell terminal. If you want to get inspiration about the headers and payload itself, use Search-AzGraph with your desired ARG query and provide the -Debug switch parameter. Lets take a look at the details of one such VM: The first thing that you can notice is that the IPs are within a property bag called instanceView. Learn more. { This is very nicely described herehttps://johan.driessen.se/posts/Fixing-the-missing-Azure-Context-in-Azure-Powershell/. The thing is that ARG depends on the various providers to get their data. This is the case for, Not all Kustos language features and functions are supported by Azure Resource Graph, as Microsoft states explicitly, A virtual network (VNet) is required in ARM for a VM to be hooked to. }, $Report | Export-Csv "c:\users\$env:username\documents\Azure_VMs_Status.csv" -Force -NoTypeInformation. The maximum number of rows obtained per query if you attempt to use Search-AzGraph against a large enough VM inventory will be 1000. You can use the below Azure PowerShell cmdlet to retrieve the properties of all the Virtual Machines under a specific Resource Group. The fix is the same, just use the tostring() function to convert it to a string primitive type. Q: Where can I get more info about model view and instance view?A: Thats a good question, and unfortunately I currently dont have an answer. Q: Back in listing 22, why not loop while the number of results returned is greater than 0, instead of verifying whether the last result set had a size equal to that of the page length?A: Doing that will trigger another query to be sent, which will be guaranteed to return 0 results. Because a VM with multiple vmNics can have some of them disconnected, and once this happens, those vmNics can be left orphaned, with no parent VM id stamped (the value is null). What we do want to know is the differences at the networking layer between the 2 models, in order to build the ASM ARG query appropriately. The array will contain the Azure subscription ids that happen to be inside the current subscription batch. Latest Azure Meetup Berlin Recording: 7 Habits every Azure Admin must have! Coming back to the output in figure 10, lets replace the ids for the public IPs with the real addresses. With wait, the shell will wait for all the background jobs to complete. (LogOut/ A REST client can be used against Azure Resource Graph. To get an idea about the time the code above in listing 27 takes, running it across 4k VMs homed in 150+ subscriptions took about 20 minutes. Of the 3 methods above, well only look thoroughly at how to use Powershell to interact with ARG. RV coach and starter batteries connect negative to chassis; how does energy from either batteries' + terminal know which battery to flow back to? Eg just a vmNic that only has a public IP?A: For IPv4 at least, a private IP is required for a vmNic, as clearly stated here https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-network-interface-addresses#ipv4. You can actually see these headers back in picture 34. Lets move on to the public IPs. To get the particular azure VM using CLI, we need to provide the VM name and resource group name. And that we can achieve using the join Kusto operator (described here)against the queries seen in Listing 5 and 7. And to get there we simply need to find another column other than the vmNics id to link our data, as follows: we know that each VM has an id (one is partially visible in figure 1), and wed just need something to link all the vmNics to their parent VM (as a vmNic can only be hooked to a single VM). The downside is that the file is written to using the JSON format, which looks a bit cumbersome when opened in Excel: The quick fix is to parse the private and public IP arrays and convert them, as such: And this is how the output now looks in Powershell: The final Powershell code further into the article takes into account all the issues. Set-AzContext -SubscriptionName $Subscription.Name foreach ($vm in $vms) Unlike ARM, ARG allows using complex filter and join operations based on different columns whose data comes from different providers, all across multiple subscriptions. Showing first 1000 of. Youll get to see the request and the replys respective header and payload. You can read the details here: Deprecation of Switch-AzureMode. If you dont have more than 1,000 subscriptions, you can gain a few seconds per runtime by removing this extra batching code from the final script. foreach ($VM in $VMs) { Heres just the top properties slot, as its returned by ARGE: What wed like next is to extract just the private IPs and the public ones. You can use the below PowerShell script<\/strong> to pull the list of all subscriptions & their resource groups & resources in it. Note that we use array splatting instead of object splatting. The actual functionalities that are either allowed or not are presented here. Our pagination code will simply run the same exact Kusto query in a loop, and use a rolling window against the same result set. This Microsoft article explains further: When an Azure resource is updated, Resource Graph is notified by Resource Manager of the change. The -InstanceId parameter allows you to specify one or more VMs to start. $RGs = Get-AzureRMResourceGroup If youre not in a rush, then lets delve deeper into the topic and explore the following: Azure Portal can show in the Virtual machines blade both classic (ASM) and the regular ARM VMs by filtering either on Virtual Machines (classic) or Virtual Machines. Powershell can be used to retrieve both ARM and ASM VMs as well. Well only add a private IP, and skip associating a public IP: So at this stage running the query in listing 1 will result in the properties.ipConfigurations array containing not one, but two elements. This was the case in this articles figure 14, where the properties.IPConfigurations[indexer].properties.publicIPAddress.id slot had to be converted to string first. {Name:name, PublicIPs:publicIps, PrivateIPs:privateIps}" --output tsv >> VMs.csv & done; wait; date +"%T". Azure DevOps Sprint Update: Cross Staging Variables supported natively, How to Preview and Test a Changing YAML Pipeline on Azure DevOps, Permalink: https://www.razorspoint.com/2020/01/29/get-all-vms-grouped-by-subscription-with-azure-resource-graph/. Theres currently a bug in ARGE that requires you to repeatedly click the drop-down, and scroll through the list of subscriptions, before the full list of subscriptions that you have access to shows up. $VMStatusDetail = $VMDetail.Statuses.DisplayStatus -match "^VM . Why am I getting an error that the type is dynamic? A discussion around public/private IP addresses, with some very interesting notes, is here https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-network-interface-addresses. When this query runs, all 2000 results are returned: Q: Im trying to do pagination using the Search-AzGraph cmdlet against a query that contains the limit operator, and Im seeing a strange outcome when trying to use the -Skip and -First parameters as described herehttps://docs.microsoft.com/en-us/azure/governance/resource-graph/concepts/work-with-data#paging-results. One important question is whether Azure CLI can retrieve classic VMs? From the standpoint of what were trying to achieve, the 3 big differences between the models which are in the table at the end of the linked article are the following: Machines under the old ASM model cant be created anymore, unless youve been using VMs through this model in Feb 2020, as perhttps://docs.microsoft.com/en-us/azure/virtual-machines/classic-vm-deprecation#how-does-this-affect-me. "VMLocation" = $vm.Location {Name:name, PublicIPs:publicIps, PrivateIPs:privateIps}" -o table will return the VMs in the current context (current subscription) and parse the IPs nicely: As for the command itself: the -d switch retrieves all the details for the VMs (without it youll get neither the private nor the public IPs). Option 1: Azure Resource Graph Explorer (ARGE). Copyright RazorSPoint. One thing to be aware of is that theres no ordering whatsoever, as background jobs write as soon as they finish, and theres also no guarantee that theres ordering in each az vm list command (as explained here). Making statements based on opinion; back them up with references or personal experience. The >> is the append operator in bash (> writes to the file, but overwrites). # VM Status (running/deallocated/stopped) As weve seen previously, the networkInterfaces slot is actually an array, which in our case contains a single entry, corresponding to the only vmNic. Are there conventions to indicate a new item in a list? Why the latter, taking into account that according to the ARM model there cannot be a VM that doesnt have at least one vmNic connected? In short, ToString() needs to be called. Each aggregated result from the inner loop thats calling Search-AzGraph repeatedly gets added to the final result set, as the subscription batches are iterated through. Using the numeric example here, the rolling window starts at index 3000 and spans for 1000 rows. Q: Ive come across an important note in this articlehttps://docs.microsoft.com/en-us/azure/governance/resource-graph/concepts/work-with-data:When First is configured to be greater than 1000 records, the query must project the id field in order for pagination to work. The table is just one of the the various outputs that Azure CLI supports. When the query runs, only 1000 results are returned, just like the article states. write-host $vm.Name , $vm.ResourceGroupName , $vm.HardwareProfile.VmSize , $vm.OsType , $vm.ProvisioningState , $vm.Location , $vm.StorageProfile.OsDisk.Name So for every subscription, we set the active context to that subscription and populate the variable $vnets with all Virtual Networks in that subscription. Each element will consist of a properties slot (not to be confused with the ipConfigurationss parent properties one) that in turn will contain the private IP for the respective IP configuration and optionally the public IP (if one is associated). If however we keep the id of the VM (make the 3rd line of either ARM/ASM query to project the id as the first field), then ARG will honor a -First value between 1000 and 5000, and return an equally sized result set.
