To work around it, for an uniquely named subscription, just use Get-AzSubscription | ? First, the ARG queries need to be sorted, otherwise the paging mechanism will not work. Finally, I would use the summarize function with make_set, which allows me to group the array by one property with another property. Change). } Note in the 3rd output below that the vmNic returned is still the first one, as opposed to the second one. Q: Im trying to run a Kusto query in ARG thats using the join operator. More info about Internet Explorer and Microsoft Edge. 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. If you wish to list all the virtual machines in an Azure subscription, execute the "Get-AzVM" command in an elevated PowerShell window. Wed simply have to join them to get to our goal. However, if you have access to multiple Azure Subscriptions, then its very important that you set the context to the one you intend to run commands against. Luckily, ARG can be used to query VMs provisioned using both models. This leads us to the query below: f you remember our very first join, weve run into an error the first time we tried it. As it turns out, Microsoft Graph behaves in a similar way when doing pagination against it, couple with top, as it was discussed in an earlier article here. Your step by step approach explain a lot how it works and hot it should be developed for similar tasks. 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. We are aware of this issue and it should be solved starting October, lowering this timeframe to less than 1 minute. In this section, well construct the final Kusto query bit by bit. #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 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. Hopefully by the time you read this, its already done. Whats going on?A: If for any reason you dont see VMs returned that you know you have access to (eg theyre in subscriptions where you already have access) see the last note herehttps://docs.microsoft.com/en-us/azure/governance/resource-graph/first-query-powershell#run-your-first-resource-graph-queryabout the default context. It would appear further that things are simple, with horizontal-lines-icon indicating primitive types, while the grid-icon represents a dynamic type. The thing is that ARG depends on the various providers to get their data. In this Azure PowerShell article, we will discuss how to get the list of virtual machines under your Azure subscription. Limit of 3 join in a single query. 2023 All rights reserved. How many such matches do we have? You can retrieve the lists of Azure Virtual Machines based on certain filter conditions. After youve run the previous command and know either the name or id of the Azure Subscription to need to execute commands against, then you will need to actually set the Azure PowerShell context to that subscription. Even more, if the value for -Skip is large enough (larger even than the number of entries in the result set), then youll still get results back, in a sort of wrap-around bug, as seen below for the same query: If you keep the original column containing an id, pagination appears to work even without sorting. The title could also be Everything you need to know when using Kusto and Powershell for platform management. $VMReport += New-Object psobject -Property @{ Well get rid of the vmId one weve used when building the query, since its no longer required. In ARGE, on the left side, the tables and their columns are shown: Note in the previous picture something that doesnt refer to an actual element: an `indexer` entry signals that the property above is an array (eg networkInterfaces). This is the terminology the Azure PowerShell uses to refer to the currently selected Azure Subscription information that commands will be executed against. For example, for a VM with 3 private IPs, the only thing shown is a cryptic {, , } instead of the array containing those 3 IPs. Even more, trying to display the array wont return anything: Why this is so is explained here. This script will collect all VMs including the status, OS Type, Version, VM, Location, Resorce Group and Subscription Name. "type": "Microsoft.Network/networkInterfaces/ipConfigurations", "etag": "W/\"dbd7c289-d2dc-46a8-b767-ef6b5f818920\"". We know the rows for the left table are unique as we dont expect for a VM id to show up twice. 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/ In the documentationthere are a couple of key things worth knowing: It turns out that if no join flavor is specified and for our last query, this is just the case Kusto will assume that we want a innerunique type of join. Using Azure CLI to query ARG will be touched upon at the end of this article, but only briefly. Below you can see the result of running Search-AzGraph by specifying it should return the first 2000 network interfaces. Ive created a user voice entry here https://feedback.azure.com/users/1609311493. When the number of results is no longer equal to the page size, it means our rolling window is right above the last set of entries (or is looking at a completely null set, if the very last row fitted neatly into the previous filled page). Q: Im trying to solve the problem back in listing 17, by using on $left.vmId =~ $right.vmId instead of using tolower(), so that this rule is applied by the join operator. Even if you keep yourself active in that session, Cloud Shell still issues tokens valid for 1h, so the cmdlets running will start erroring out after that time, with the dreaded The access token expiry UTC time is earlier than current UTC time . However; most disks (especially if auto created) will have the vm name as part of their name. This Microsoft article explains further: When an Azure resource is updated, Resource Graph is notified by Resource Manager of the change. For our final Powershell code, this means were going to have an additional layer of pagination, at the level of subscription batches. Even more, if using Azure Cloud Shell, the session will timeout after 20 minutes by default. Our code will consist of a loop that makes sure that the rolling window is moved across the whole result set. Eg can I be sure that properties.IPConfigurations[indexer].properties.publicIPAddress.id is a string?A: As per the previous question, that particular slot is not a string. As described here in the note, for the classic deployment model, the Azure classic CLI must be installed. 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. Resource Graph then updates its database. The instance view is the instance level status of the virtual machine. Update 10/6/2020: On Oct 1st, Microsoft has updated their documentation here https://docs.microsoft.com/en-us/azure/governance/resource-graph/concepts/query-language#supported-tabulartop-level-operators to state that limit doesnt work with -Skip. { Since each of the 2 tables contains a column called publicIpId, Kusto has to somehow put both of them in the result table, so it resorts to renaming one of them to a different value, hence appending a 1. Martin is right, the title should be changed to : Everything you need to know when using Kusto and Powershell for platform management. Can the Spiritual Weapon spell be used as cover? Using the numeric example here, the rolling window starts at index 3000 and spans for 1000 rows. PS C:\> az vm list -otable. If you happen to be a global admin for your tenant, then you can grant yourself access to all subscriptions within via a simple setting. foreach ($vm in $vms) Heres how this looks like for Insomnia: Next, provide the payload as described here and use the Kusto query in listing 23. Well, theres the public IP id of our test VM that corresponds to the private IP 10.0.1.4 which also shows up in table 13, next to the 104.40.204.240. You can add -o table at the end if you're looking for something a bit prettier. Once the query will work for this VM, well be able to extrapolate it to all VMs.Lets start working towards our final query by creating a VM (name: JustOneTestVM) that has a very simple configuration: just one vmNic (name: justonetestvm915) connected to a virtual networks (name: JustOneVnet) subnet (name= JustOneSubnet). 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. Story Identification: Nanomachines Building Cities, Ackermann Function without Recursion or Stack, Book about a good dark lord, think "not Sauron". 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. He has a passion for technology and sharing what he learns with others to help enable them to learn faster and be more productive. 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. $VMs = Get-AzureRmVM -ResourceGroupName $RG.ResourceGroupName This script will collect all VMs including the status, OS Type, Version, VM, Location, Resorce Group and Subscription Name. How to query the various AppService minTlsVersion settings using ARG The =~ will do the match case-insensitive. The association to a VNets subnet is done at the vmNic level, therefore all its IP configurations will be hooked to the same subnet. The final stitched results most likely wont be sorted overall, so well have to handle that manually, by calling Sort-Object right before exporting the CSV files. How did StorageTek STC 4305 use backing HDDs? Heres the partial output when supplying the ARM query in listing 23: 4 attributes appear to control how many requests can be made. 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. So unlike with Azure Resource Management, we wont have to query different providers individually to get data about VMs and their network configuration. The net result is that the values are seen as completely different by the join operator since it acts in a case-sensitive way, and no rows are matched, which yields the result above. The direct link for ARGE is here. az vm show command finds the VM from the list using parameter -n (VMName) -g (resource group Name). The outer one will iterate through the subscription batches, while the inner one handles the pagination of Search-AzGraphs result set. $Report = ForEach ($Subscription in $Subscriptions) { 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. As weve seen previously, the networkInterfaces slot is actually an array, which in our case contains a single entry, corresponding to the only vmNic. 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. The command becomes:for i in `az account list --query "[]. This is how you can get the lists of Azure Virtual machines using Azure PowerShell. 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. So getting the actually assigned values for the various parameters (such as IP addresses) should come from the instance view. This article covers some of the Azure PowerShell commands that you can use to create and manage virtual machines in your Azure subscription. The output is below: Copy the tenant domain and paste it in the following commands. Well just apply the tolower() function to both vmId columns, which will make the join key consistent between the 2 tables: The only thing left to do is to aggregate the IPs, similar to how it was initially done, using the summarize operator and the make_list function weve introduced back in listing 12. Sorting is recommended although strangely not made a requirement by Microsoft in its own documentation here. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Although not effective immediately, eventually all the subscriptions will become available. Making statements based on opinion; back them up with references or personal experience. 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. Learn how your comment data is processed. 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. Besides writing articles in his blog and German magazines, he is still contributing to the SharePoint Developer Community (and PnP SharePoint) to help to make the ALM part a smoother place to live in. A REST client can be used against Azure Resource Graph. 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/. The empty public IP id showing on the 2nd row in figure 10 cant be matched to any id in figure 13, as theres no empty string showing as id in this latter figure, so the join operator leaves it out altogether. I needed to get the machines and public IPs, perfect! Q: Where can I read about the networking model under ARM, and how the vmNics, VNets, subnets, public IP addresses and all the other types of objects come together?A: A very good description of the networking concepts is here https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-multiple-ip-addresses-portal, in the very first section.
