azure powershell list all vms in subscription

An Azure service that is used to provision Windows and Linux virtual machines. 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. One quirk to be aware of is that aside from the id (recognized as the primary key by ARG), Search-AzGraph includes a column in the result set, called ResourceId, which contains the same values as the id itself (if you run the query in ARGE youll notice that this isnt the case, and this column doesnt show up). Sebastian is an Azure Nerd with focus on DevOps and Azure DevOps (formerly VSTS) that converted from the big world of SharePoint and O365. $vms = Get-AzureRmVm Note that the row_number function (described here) is 1-based.| extend rn=row_number()| where rn>3000. {Name:name, PublicIPs:publicIps, PrivateIPs:privateIps}" --output tsv >> VMs.csv & done; wait; date +"%T". The very first thing were going to look at is a generic model for how an ARM VM connects to the network infrastructure in Azure. Which describes quite well that the leftouter join flavor does. Were not going to go over the ASM model in detail, as things are very well explained here. This will define which Azure Subscription you are executing commands against. 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. One way of solving this is to explicitly specify the property, which will result in a string containing all the IP addresses separated by the chosen separator, which by default is space. If youre using it from a local machine, use az login first; if youre using Cloud Shell bash, youll get authenticated directly. {id:id}" --output tsv;do az account set --subscription $i; az vm list -d --query "[]. Well keep the VMs id, to be able to differentiate between identically named VMs across different subscriptions, and also sort the result set. Meanwhile, this cmdlet connects you to an Azure tenant with an authenticated account. {name:name,disk:diskSizeGb}'. 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. This will evidently result in a lower number of VMs in the final report as opposed to what actually exists. Coming back to the output in figure 10, lets replace the ids for the public IPs with the real addresses. $Subscriptions = Get-AzureRmSubscription | Where-Object { $_.Name -in ("Prod", "Dev") } 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). What date does is pretty obvious, whats not so obvious is the %T format, which simply outputs the time (minus the date). Querying ARG can be done using your favorite REST client (eg Insomnia), directly from Microsofts documentation portal hereor better still, Azure Resource Graph Explorer (ARGE) can be used. This article covers some of the Azure PowerShell commands that you can use to create and manage virtual machines in your Azure subscription. This is convenient, as were after extracting both the modern, ARM-based VMs, as well as the ASM ones, known as classic VMs, in this article. If a law is new but its interpretation is vague, can the courts directly ask the drafters the intent and official interpretation of their law? From the join operators documentationIve picked up the rightanti join flavor. We make use of First and third party cookies to improve our user experience. 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. Lets do something about the public IPs, so the real addresses are shown, instead of just the id. The output contains a row for each match of this row with rows from the right. For our final Powershell code, this means were going to have an additional layer of pagination, at the level of subscription batches.

Whats wrong?A: If you cross-check joins documentationyoull find that the equality-by-value rule is only allowed with the explicit == operator. If you would like to list virtual machines from Resource Groups listed in a text file, using the following PowerShell script would work: $ResGroups = "C:TempResGroups.TXT" $ReportFile = "C:TempAllVMsInAzure.CSV" Like. 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. More info about Internet Explorer and Microsoft Edge. Note below the 2 output rows in the lower left. Enjoy unlimited access on 5500+ Hand Picked Quality Video Courses. It must be, as ARG is the one used for the Azure portals search feature, as stated here. 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. 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. There was an article herewritten about a year ago, stating that dynamic IP addresses couldnt be retrieved using ARG. Set-AzContext -SubscriptionName $Subscription.Name The second way, using Powershell, will output any multiple IPs separated by a space. 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. To start multiple VMs, separate each instance ID with a comma. 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 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. Using the Search-AzGraphs -First parameter to obtain only the first row also works as expected, as the 2nd output shows. Please use below powershell script, read out the comments for each line so that you can understand : //Get All Subscriptions Q: Im getting No tenant found in the context. Azure CLI and Powershell can be used to run and obtain the result sets for ARG queries. Once the Azure subscription is set, we can use the below command to retrieve the Azure VMs. The warning will still be generated in the script as its written in the article, if the number of the last result set is equal to that of the size of the page, since the next query will again return 0 results. Well start with a very simple VM, and keep adding network elements to it until its representative for a VM with an advanced network config, as the picture above showed. In this case, as you have issues with IPs updating, thats the Network resource provider that is actually not tracked by ARM directly. Some resources may be missing from the results. Hence the inner kind will be the one well use, and in the final result well get a number of rows equal to that of the right table (we know the left table contains unique entries, so all combinations that join creates will essentially result in the right table that has the corresponding VM row appended). We know the rows for the left table are unique as we dont expect for a VM id to show up twice. One small problem is that since the ARM/ASM ARG query runs against a specific subscription batch, the guarantee that the results are ordered is only per batch, as its the ARG query thats doing the sorting within. 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. 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. 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. Once you connect to Azure with the Connect-AzAccount cmdlet, you can use the other cmdlets in the Az PowerShell module. "VMLocation" = $vm.Location 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. Your step by step approach explain a lot how it works and hot it should be developed for similar tasks. 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. In ASM, , Public IP addresses are independent resources from the VMs under the ARM model. We start off by getting all the subscriptions available and running them one by one through a for each loop. And Search-AzGraph will generate the following warning WARNING: Unable to paginate the results of the query. In terms of runtime, running each query as part of option 1 should take seconds at most, ideally below 1s if youre targeting only a few thousand VMs. The columns and their values are identical for the 2 rows except for one extra column that was added, called ipconfig. Consider if one or multiple VMs get deleted when the set of queries is running, in the middle of pagination.

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. Compare this to the synchronous version before, which takes in excess of 40 minutes. To keep things consistent, a few naming conventions are in order: From the above, it follows that a property bag can contain other property bags within, and so on, as described in this section. The timeframe for getting this notification can be anywhere from 10 seconds up to 30 hours unfortunately. For the first issue, consistency, take the query and its result below: This shows how running the very same command returns different results, although the Azure infrastructure wasnt changed in any way. Although not effective immediately, eventually all the subscriptions will become available. Theres nothing to expand here as weve done previously, as each entry corresponds to a single public IP. $VMStatusDetail = $VMDetail.Statuses.DisplayStatus -match "^VM . Example: The below Azure cmdlet will help you to retrieve the lists of Azure Virtual Machines whose name starts with TsInfoVM. This is very nicely described herehttps://johan.driessen.se/posts/Fixing-the-missing-Azure-Context-in-Azure-Powershell/. Without at least read permissions to the Azure object or object group, results wont be returned.. Lets also write the output to a file, and make sure this file is removed in the beginning, if it exists. { 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. Similarly, its theoretically possible to have doubled results, eg if a VM gets created inside a page bin thats past that which the current query feeds. Use to use this before MS broke the hidden tag (| where tags[hidden-link-ArgMgTag] has MyManagementGroup). Of course, I started with a normal Az PowerShell module and it's cmdlets. With the PowerShell collect details about all Azure VM's in a subscription! Q: In this article its stated that First currently has a maximum allowed value of 5000, which it achieves by paging results 1000 records at a time. Wouldnt it be more efficient to repeated queries and retrieving only the first 1000 results, as opposed to relying on the Search-AzGraph to perform the pagination itself against the 5000 maximum value for the -First parameter?A: No, as youre paying the overhead for sending/receiving the smaller requests. Why are non-Western countries siding with China in the UN? If I press Ctrl+Z the background jobs still seem to be running. For example, to cancel all the background jobs invoked by the commands in listing 28, well use the fact that all the jobs get spawned by the az command, thus we can run pkill -f az. May be used within a single table or between the Resources and ResourceContainers tables.. Published with WordPress. 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. So unlike with Azure Resource Management, we wont have to query different providers individually to get data about VMs and their network configuration. Same as for the non-ARG Powershell approach, you might run into The current subscription type is not permitted to perform operations on any provider namespace. As perhttps://docs.microsoft.com/en-us/azure/governance/resource-graph/overview#permissions-in-azure-resource-graph:To use Resource Graph, you must have appropriate rights in Role-based access control (RBAC) withat least read access to the resources you want to query. 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. (Code: Default). Writing works in parallel, as each background job that happens to finish will append its data to the CSV file. If you have more than 1,000 Azure subscriptions, theres a problem, since an ARG query sent via either Powershell or Azure CLI will only run against 1,000 of them. With wait, the shell will wait for all the background jobs to complete. How do you comment out code in PowerShell? Well add one more row to our query, so it becomes: This is what we were after however lets not forget that weve been working against a VMs single vmNic all along. 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. What's the best way to determine the location of the current PowerShell script? Notice that each call needs a specific subscription. 3 very important issues need to be kept in mind, and well discuss each next. From my experiments (using both Search-AzGraph and Insomnia) Ive consistently obtained the values below in the reply to the query seen in Listing 23 across some 4k VMs stored in 150+ Azure subscriptions. The SQL-like language used within the Azure Resource Graph Explorer is called Kusto, with a capital K. Were not going to delve into the details, but instead just focus on the concepts well need for our goal. 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. Resource Graph also does a regular full scan. foreach ($VM in $VMs) { This is how you can get the lists of Azure Virtual machines using Azure PowerShell.
