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(). {name:name,disk:diskSizeGb}'. 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. Thanks so much, this is a great article. In order to use Powershell to run our ARG queries, well need the Search-AzGraph cmdlet, which resides in the Az.ResourceGraph module. But grouped by subscription id. What went wrong? The answer is included in the link above, and consists of a few points. Q: Im using a projected column whose values are copied from one thats in the Resources table, and whose type appears to be string. 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. The answer here sheds light on both questions, as follows: With both the ARM and ASM ARG queries ready, lets see what we can use aside ARGE to interact with them programmatically. So instead of just one row as the result of the query, well have 2. Using the Azure CLI, we can use the az vm list command to get a list of all VMs in the current subscription. "internalDomainNameSuffix": "jjj0d3guv4pullc5gyuom32fob.ax.internal.cloudapp.net", "id": "/subscriptions/6506b559-5861-471b-aa74-11b06d0688a3/resourceGroups/JustOneTestRG/providers/Microsoft.Compute/virtualMachines/JustOneTestVM", "id": "/subscriptions/6506b559-5861-471b-aa74-11b06d0688a3/resourceGroups/JustOneTestRG/providers/Microsoft.Network/networkSecurityGroups/JustOneTestVM-nsg", a primitive scalar data type value (such as, Arrays can also be defined, and are easily spotted by the use of, The table used in this query is Resources, indicated with green, The columns that fit on the screen under the Details pane, belonging to the querys single result are circled in red, Of these columns, some of their types are primitive scalar data types, holding just one piece of information. Lets also write the output to a file, and make sure this file is removed in the beginning, if it exists. Change). After all, tsv in the output type stands for tab-separated values. foreach ($sub in $subs) 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. As we wont care about most of the columns, lets just keep the public IP id and address using the query below: The result is below. If no -Subscription value is specified, then Search-AzGraph will perform the query against the whole tenant, across subscriptions, which is what were after actually*. How to fix this problem? Note below the 2 output rows in the lower left. He has a passion for technology and sharing what he learns with others to help enable them to learn faster and be more productive. To use the join operator on publicIpAddress youll need to call tostring() first to transform them into strings. This script will collect all VMs including the status, OS Type, Version, VM, Location, Resorce Group and Subscription Name. On a scale of 1 to 10 this easily scores 100! Since theyre obtained after one call, its safe to assume that 15 is the number of requests that can be made in 5 seconds by default, which this articleconfirms. What wed hope to get is the table in figure 10, with the same 2 rows corresponding to the 2 IP configurations defined on that vmNic, but with one single change have the real public IP address showing instead of the cryptic id. For the right table, we do expect for at least some of the VM ids to show up twice, corresponding to VMs that have multiple IP configurations or multiple vmNics; wed also expect to have cases where the some of the vmNics parent VM id is null. What can I do in the meantime? 2023 All rights reserved. To understand, we need to take a closer look at the join operator and how it works. What we actually want is to aggregate all the IPs per each VM. For every such match, output a row in the resulting table that consists of all the columns in the first table plus all the columns in the second one. //Display the current processing subscription Heres a screenshot of an example error message. $VMReport += New-Object psobject -Property @{ Syntax: The syntax of the Get-AzVM is as below. And I did it! Once, I have executed this command, I got two virtual machines as the output. Select-AzureRmSubscription -SubscriptionId $sub.SubscriptionId -ErrorAction Continue Part 1: Working With Azure Key Vault Using Azure PowerShell and AzureCLI Part 2: Create a Virtual machine on Microsoft Azure Part 3: Use a Azure VM system assigned managed identity to access Azure Key Vault Create an Azure App registrations in Azure Active Directory using PowerShell & AzureCLI Connect-AzureAD: One or more errors occurred. However, the public IP is only referenced by its id, as seen below, which makes sense if you think about it, as the public IP is a separate resource in the ARM model, just as the network interface resource is separate from the VM itself. 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. Please ensure that the credentials you provided are authorized to access an Azure subscription, then run Connect-AzAccount to login while running Search-AzGraph. $VMDetail = Get-AzureRmVM -ResourceGroupName $RG.ResourceGroupName -Name $VM.Name -Status See the basic steps for creating a virtual machine in. But double-checking with Microsoft Support turned out that this isnt the case. AzureRM is being discontinued, and also doesnt work with Powershell 7, as discussed on this StackOverflow thread. Well use project again to specify the columns we want to keep, and the query becomes: Notice one of the public IPs is missing, which is because we didnt associate a public IP for the 2nd IP configuration when we added it. As for the numbers, the time it took to go through roughly 4,000 ARM VMs homed in more of 150 subscriptions with the parallel background jobs was a bit under 10 minutes. Find centralized, trusted content and collaborate around the technologies you use most. Notice that the Azure PowerShell Az commands refer to the selected Azure Subscription as a context. Lets look at the private IP addresses, and understand whether a classic VM can have multiple ones, as was the case with ARM, or not. These commands are simple to execute, but important to use. Q: For one vmNic attached to a VM, can one of its IP configurations be pointed to one subnet, while a different IP configuration made to point to a different subnet?A: No. How to list the Azure VMs from the Availability set using PowerShell? But then I remembered the resource graph and wondered if I can get all VMs with subscription id, os type, VM name, resource group name, location and so on. Below you can see the result of running Search-AzGraph by specifying it should return the first 2000 network interfaces. "VMSize" = $vm.HardwareProfile.VmSize //loop through each subscription One of the problems is that the cmdlets acting on one type of VMs will not work on the other, and as such separate Powershell modules exist that contain them: Azure for ASM and Az (along with the soon-to-be-discontinued AzureRM) for ARM. if($Subscription.State -eq "Enabled") For our ARM query for example, we already have the data sorted (therefore serialized), so the only remaining thing left to do was adding the following 2 lines at the end of listing 20 in order to retrieve the rows 3000-3999 of that query. Option 1: Azure Resource Graph Explorer (ARGE). All the vmNics that you add to a VM must be connected to the same virtual network, as described herehttps://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-network-interface-vm#add-a-network-interface-to-an-existing-vm. Q: Can I be sure of the type seen in the Azure Resource Graph Explorer (ARGE) in Schema explorer on the left? Next, in the Run Command Script pane, we typed the PowerShell script text that we want to execute on the server. But trying to display the first row after skipping the very first element which in essence should yield the 2nd row doesnt work as expected. The final state of the VM, with a second vmNic having a single IP configuration that has a private IP (10.0.2.4) and an associated public one: This new vmNic (name= justonetestvm916) is connected to the same virtual network as the first vmNic (name: JustOneVnet) but to a different subnet within it (name= JustAnotherSubnet). .author-img-cert-badge { Dealing with hard questions during a software developer interview. Although not effective immediately, eventually all the subscriptions will become available. "VMName" = $vm.Name 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. The direct link for ARGE is here. Resource Graph also does a regular full scan. Heres the partial output when supplying the ARM query in listing 23: 4 attributes appear to control how many requests can be made. Well use separate CSV files to keep the ARM VMs separate from the ASM (classic) ones. This will evidently result in a lower number of VMs in the final report as opposed to what actually exists. "type": "Microsoft.Network/networkInterfaces/ipConfigurations", "etag": "W/\"dbd7c289-d2dc-46a8-b767-ef6b5f818920\"". 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. 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. But running the modified query doesnt work, and instead the following error is thrown:(Code: InvalidQuery) join: Only equality is allowed in this context. Yet we want our final query to be able to handle multiple IP configurations, not just one, as this feature was introduced back in 2017. Heres the output in ARGE, and notice the original id field thats now included: Thirdly, looking at the Powershell object returned by Search-AzGraph will not show anything for the arrays containing the IPs. Also, note that no column header is added to the file. A REST client can be used against Azure Resource Graph. Like. Well keep the VMs id, to be able to differentiate between identically named VMs across different subscriptions, and also sort the result set. Enjoy unlimited access on 5500+ Hand Picked Quality Video Courses. Lets use it to work towards our goal, of showing all private and public IPs for all VMs. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. You can use the following command to get a list of all the Azure Subscriptions your current login has access to: Get-AzSubscription If you only have access to a single Azure Subscription, then the output will only show that 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. The columns and their values are identical for the 2 rows except for one extra column that was added, called ipconfig. This is by design. How to restart the Azure VM using Azure CLI in PowerShell? "VMLocation" = $vm.Location The deprecation is part of a breaking change. Q: I would like to see what Search-AzGraph is actually doing behind the covers. How do I pass multiple parameters into a function in PowerShell? How to stop the Azure VM using Azure CLI in PowerShell? Write-Host "Processing subscription $($sub.Name)" You need to do it with the dedicated cmdlet for this. Useful if youll be automating and know that youre under the limit. 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. How about a solution that takes less than a second to get all this information: TL;DR Jump here to see how to extract all the Azure VMs + all their private/public IPs in a matter of seconds. Q: Im trying to run the simple join samples here https://docs.microsoft.com/en-us/azure/data-explorer/kusto/query/joinoperator?pivots=azuredataexplorer, but for some reason thiscant be done in the Azure Resource Graph Explorer.A: Use instead the UI here https://dataexplorer.azure.com/clusters/help/databases/Samplesto run samples. Simply query this endpoint https://management.azure.com/providers/Microsoft.ResourceGraph/resources?api-version=2019-04-01, and submit a Bearer token obtained using the Powershell lines here, as follows: Copy the access token (dont worry that its multiline) and paste it in your REST clients authentication tab. (LogOut/ Making statements based on opinion; back them up with references or personal experience. } Theres nothing to expand here as weve done previously, as each entry corresponds to a single public IP. foreach ($RG in $RGs) { The [] simply flattens the current array, as described here, while the following partjust rewrites the names of the columns in the final output. Make sure you have this one installed (as of Sep 2020, this is not present by default in Cloud Shell, and needs to be installed; the current version is 0.7.7). 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. 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.
