I just wish Microsoft would provide more advanced ARG query examples and varying kinds. Well apply tostring against the public IP ids extracted from the vmNics objects: Lets think for a moment what the output should be, before seeing the actual results. .author-img-cert-badge { Unlike adding a new vmNic, which requires stopping the VM, a new IP configuration can be added to a vmNic while the VM is running. }, This happened to me during some Azure training. How to retrieve Azure VMs using PowerShell? Not that it doesnt mean youre not allowed to run things in parallel (as well see a bit later), but the jobs you invoke have to act against a certain subscription. Your step by step approach explain a lot how it works and hot it should be developed for similar tasks. "OSType" = $VM.StorageProfile.OSDisk.OSType Syntax: The syntax of the Get-AzVM is as below. "VMOSType" = $vm.OsType Please use a different subscription. The fix is the same, just use the tostring() function to convert it to a string primitive type. According to Microsofts documentation, it is a read-only request to process data and return results. #List to store all results $Result=New-Object System.Collections.Generic.List[PSObject] #All Azure Subscriptions $Subscriptions = Get-AzSubscription #Looping through each and every subscription foreach ($sub in $Subscriptions) { #Setting context so the script will be executed within the subscription's scope Get-AzSubscription -SubscriptionName Applies to: Linux VMs Windows VMs Flexible scale sets. Once you master the basics, you can move over to Azure Resource Graph queries, herehttps://docs.microsoft.com/en-us/azure/governance/resource-graph/samples/starter?tabs=azure-cliand herehttps://docs.microsoft.com/en-us/azure/governance/resource-graph/samples/advanced?tabs=azure-cli. Lets modify our VM so that it has 2 IP configurations. As for the minimum permissions required, the Reader Azure RBAC role will do. In this case, as you have issues with IPs updating, thats the Network resource provider that is actually not tracked by ARM directly. How do I concatenate strings and variables in PowerShell? This script will collect all VMs including the status, OS Type, Version, VM, Location, Resorce Group and Subscription Name. $subs = Get-AzureRmSubscription To see these 2 limitations in action,take a look at the API call to retrieve resources in ARM here and at the API call for retrieving the network interfaces here. If no sorting is performed, the outcome will be that the results might be wrong, and in certain cases the loop will never end*. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. For our final Powershell code, this means were going to have an additional layer of pagination, at the level of subscription batches. This is the terminology the Azure PowerShell uses to refer to the currently selected Azure Subscription information that commands will be executed against. Azure PowerShell List Virtual Machines Get-AzVM The Get-AzVM command is used to get the lists of Virtual machines or the properties of the Azure Virtual Machines present under your Azure subscription. To do this, you can use the following command, and pass it either the Azure Subscription name or id: Be sure to replace the placeholder values within the above examples with the actual id and name for the Azure Subscription. Why the latter, taking into account that according to the ARM model there cannot be a VM that doesnt have at least one vmNic connected? Because a VM with multiple vmNics can have some of them disconnected, and once this happens, those vmNics can be left orphaned, with no parent VM id stamped (the value is null). He learned to love the possibilities of automation. So getting the actually assigned values for the various parameters (such as IP addresses) should come from the instance view. In ASM, , Public IP addresses are independent resources from the VMs under the ARM model. ForEach ($Subscription in $Subscriptions) { You can spot this by their null values in the respective figure, which is one of the 4 incarnations of a dynamic type, as seen above. As his focus shifted in 2017 to more DevOps related topics in the Microsoft Stack. Compare this to the synchronous version before, which takes in excess of 40 minutes. Q: Can I use Kusto.Explorer to connect directly to the Azure Resource Graph database for my Azure tenant?A: No. Useful if youll be automating and know that youre under the limit. The thing is that ARG depends on the various providers to get their data. Wow. As were doing Export-Csv at the end of our code, this will actually result in the string for the array to be written, simply because under the hood Export-Csv calls ToString(). Syntax: The syntax of the Get-AzVM is as below. It might look like magic at first, but not quite: for simply iterates through the list of Azure subscription ids, which is obtained with the az account list command that only returns the id of the subscriptions using the --query parameter. Eg heres a current bug whereby the Details tab doesnt show anything: A: Try using the preview version of the Azure portal, where the bug might have been already fixed, or not present at all: https://preview.portal.azure.com/. The important parts are, that you first filter by the resource type and then create your custom object with the pack function, then you would have all returned properties plus the new property virtualMachine. 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. In ASM, they can be associated directly with the VM, The table on the left of the join is called the outer table, while the one on the right of the join is called the inner table. How many such matches do we have? To start multiple VMs, separate each instance ID with a comma. 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. When this is the case, simply piping the output to Export-Csv directly will result in a System.Object[] entry in the private IP address column. 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. After all, tsv in the output type stands for tab-separated values. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Once the Azure subscription is set, we can use the below command to retrieve the Azure 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. Note that we use array splatting instead of object splatting. These are the values you will need to set the current context to a particular subscription. A: Its a known limitation with Search-AzGraph and the limit Kusto operator. Example: The below Azure cmdlet will help you to retrieve the lists of Azure Virtual Machines whose name starts with TsInfoVM. Even more, trying to display the array wont return anything: Why this is so is explained here. Although the documentation around the notion of instance view is rather scarce, funny enough we can get some info from the Powershell cmdlet used in the ARM model, as Get-AzVMs description herecurrently states that The model view is the user specified properties of the virtual machine. There are 2 main things were interested in: the fact that a VM can have multiple vmNics, which can be connected to different subnets, and that each vmNic can have multiple IP Configurations, each with a private IP and optionally a public one. See the basic steps for creating a virtual machine in. Well keep the vmId as a tie-breaker when 2 or more VMs have the same name across subscriptions, and well also sort by the VM name, with the final query becoming: As well see later, when going over pagination, sorting the result set has important implications, aside the cosmetical alphabetical order by VM name. Lets discuss the 2 concerns above for this case: consistency looks to work as expected, at least from my tests, as I could not reproduce the issue seen in first photo of this answer. Select-AzureRmSubscription -SubscriptionId $sub.SubscriptionId -ErrorAction Continue Youll notice the Search-AzGraph shows twice in the code below, and that is because it doesnt support 0 as the value for -Skip (if you attempt it, you get The 0 argument is less than the minimum allowed range of 1), so the very first batch of results needs to be treated on a separate if branch. $myResourceGroup - The name of the resource group that contains the virtual machine. All rights reserved. Why are non-Western countries siding with China in the UN? Duress at instant speed in response to Counterspell. Well run the pagination code twice first for the ARG query handling ARM VMs, and second for the ARG query handling the ASM ones. 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. Q: Is there a way to supply the Kusto queries in an embedded direct link, like some of MSs own documentation does?A: Yes, simply encode the Kusto query using an online URL encoder (such as this), then append this tohttps://portal.azure.com/?feature.customportal=false#blade/HubsExtension/ArgQueryBlade/query/. Q: Is this Kusto language brand new?A:According to the history of Kusto here, the language first showed up in 2014. How to start the Azure VM using Azure CLI in PowerShell? Note -This script will collect all VMs including the status, OS Type, Version, VM, Location, Resorce Group and Subscription Name. This will evidently result in a lower number of VMs in the final report as opposed to what actually exists. Sorting is recommended although strangely not made a requirement by Microsoft in its own documentation here. As we dont need most of the columns, lets just keep the IPs were interested in, along with the vmNic id. How to Export the Azure VMs using PowerShell? Assuming you have Az Module installed, try: Thanks for contributing an answer to Stack Overflow! Subscribe to RSS . I want to thank you for creating one of the best and most comprehensive about Azure Resource Graph (ARG) queries and how to get them to work. While the teams are working hard to make services available in these regions, it can happen . The array will contain the Azure subscription ids that happen to be inside the current subscription batch. Please use below powershell script, read out the comments for each line so that you can understand : //Get All Subscriptions "VMName" = $vm.Name Q: Whats the parent VM id for a disconnected vmNic? I ran into a similar issue and I was able to use a simple ForEach Loop to get this working. The public IPs, as defined in properties instanceView property bag, is an array (note the information is enclosed within []). } The output is then written to disk as CSV files whose filenames are timestamped. 2023 All rights reserved. As described here in the note, for the classic deployment model, the Azure classic CLI must be installed. The -Skip will tell where the result window starts from, and the -First parameter will tell how many rows will be retrieved from that starting point. So that might be helpful if you can view and map back that way. The nice thing about the CLI is that you can quickly get all the private and public IPs, without having to resort to anything extra. The actual functionalities that are either allowed or not are presented here. "az vm show" command finds the VM from the list using parameter . Heres a look against 3000 results the first runtime is computed against the query ran a single time, while the second running the query 3 times on 1000-capped rows per query: Q: Is sorting required for pagination to work with Search-AzGraph?A: From my experiments with v0.7.7 of the Az.ResourceGraph module that contains this cmdlet, the outcome of an unsorted query is wildly different whether you have an id column in your querys output or not. The parameter - Include DisplayName is needed so I can get the tenant display name and subscription name which is not coming by default when you use project. The ResourceId always gets included if the primary key (the id) is also present, regardless of how many rows are asked for via -First (it can even be 1 and the column is there). The maximum number of rows obtained per query if you attempt to use Search-AzGraph against a large enough VM inventory will be 1000. { } But I did mentioned the problem here. 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/. Both have a brief intro here. From the Azure Active Directory blade, toggle the option below to Yes: Important: if the global administrator account doesnt have access to at least one Azure subscription, nothing will be visible, despite the self-elevation. Q: Is there an official legend of the icons within ARGE on the left side?A: Theres a grid icon for the resources table, which makes sense. There are bits and pieces around the web like this querythat retrieves just one public IP per each VM regardless if they have multiple assigned but no private IP whatsoever. 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. Yet even if you have the id in your query, it still doesnt mean that itll always work, and using it as such will expose you to the mercy of the internal cmdlets implementation as it may or may not use the original id column as the primary key leaving you with different outcomes if you run the same cmdlet multiple times, or potentially buggy results. "VMOSDisk" = $vm.StorageProfile.OsDisk.Name Adding on this, we just loop over all our subscriptions and add the results to a single list, This, however, does not include the power on/off state of the vms. Q: Im using a projected column whose values are copied from one thats in the Resources table, and whose type appears to be string. write-host $vm.Name , $vm.ResourceGroupName , $vm.HardwareProfile.VmSize , $vm.OsType , $vm.ProvisioningState , $vm.Location , $vm.StorageProfile.OsDisk.Name If using Excel to work with the output file, make sure youre importing the file by using tab as the delimiter, otherwise it will split columns by default using a comma, which is not what we want, given that only multiple IPs are separated by a comma. You need to use the Azure Resource Manager mode to access the new VMs: Note that Switch-AzureMode has now been deprecated (https://github.com/Azure/azure-powershell/wiki/Deprecation-of-Switch-AzureMode-in-Azure-PowerShell). Q: Can an additional IP configuration be added to an existing vmNic while the parent VM is running?A: Yes. The direct link for ARGE is here. Well get rid of the vmId one weve used when building the query, since its no longer required. Cloud Shell only appears to support version 2 of the CLI. Specifically, consider the query below, which retrieves all the vmNics in a test Azure tenant: Limiting the number of results to 2, using the limit operator within the query itself, works as expected as seen in the first output below. Q: Can a VM be left without any vmNic after it has been created?A: The last vmNic hooked to a VM cannot be detached, as described herehttps://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-network-interface-vm#remove-a-network-interface-from-a-vmin the note: If only one network interface is listed, you cant detach it, because a virtual machine must always have at least one network interface attached to it.. How to query the various AppService minTlsVersion settings using ARG The problem is the same one seen back in figure 14, and has to do with the fact that the the vmId column has the type dynamic, which join doesnt support. The same will occur for this query as well, if you try to run it as-is. This means that the export will most likely never finish for a large VM inventory unless youre interacting with the respective browser window in some way for the duration the code runs. Theres no IP whether private or public that can be found in any of the results columns, and that includes properties as well. Once I have executed the above Azure PowerShell cmdlet, you can able to see the output below. Like. //export to csv format And it turns out its quite simple to aggregate the data in this way, by using Kustos summarize operator together with the make_list() function. { "VMProvisioningState" = $vm.ProvisioningState "VMName" = $VM.Name Use the following command to view the current Azure Subscription (or context) that Azure PowerShell is scoped against to execute commands for: When the Get-AzContext command is executed, the command prompt will return the primary information for the Azure Subscription that is currently selected for the Azure PowerShell context. Again, separate versions need to be used, depending on whether ARM or ASM VMs are targeted.The problem with both the Powershell and the Azure CLI approach is that one can only collect information about a set of VMs only after switching to a specific Azure subscription, which burns quite a lot of time. Before that, we need to make sure the Azure is connected to the desired subscription, if not use the below command to set the Azure Subscription.
