The title could also be Everything you need to know when using Kusto and Powershell for platform management. 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. The CLIs are invoked differently, with v1 using azure, and v2 using az. How do I pass multiple parameters into a function in PowerShell? Resource Graph then updates its database. You can use the following command to get a list of all the Azure Subscriptions your current login has access to: If you only have access to a single Azure Subscription, then the output will only show that subscription. In this Azure PowerShell article, we will discuss how to get the list of virtual machines under your Azure subscription. As for the ARM code above, speed is not its main quality, as theres no parallelism whatsoever (eg Powershell background jobs). 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. After all, tsv in the output type stands for tab-separated values. 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. foreach ($vm in $vms) This leads us to the query below: f you remember our very first join, weve run into an error the first time we tried it. I have discussed with Microsoft Support, and the Product Team is due to update the article. While following labs, I created resources in my subscription instead of the provided Azure Pass Sponsorship., I also realized I had to set this separately for the Azure CLI using az account set for the portions of the labs using those commands. Before you deep in, make sure you have right privillage to login via Azure portal, Azure CLI or AzureRM module install on your local machine to run this script in powershell terminal. It follows that the answer to the 2nd question is also no. You can add -o table at the end if you're looking for something a bit prettier. foreach ($sub in $subs) Most likely this is tied to the notion of serializing the row sets, as described here, as sorting is one way to achieve it. And that we can achieve using the join Kusto operator (described here)against the queries seen in Listing 5 and 7. Its the public IPs that are optional. az vm show command finds the VM from the list using parameter -n (VMName) -g (resource group Name). The net result is that the values are seen as completely different by the join operator since it acts in a case-sensitive way, and no rows are matched, which yields the result above. After executing the above Azure PowerShell cmdlet, I got the below output, You may also like following the below articles. When you have the requiremen to get the lists of Azure Virtual machines under a specific location, you can use the below Azure PowerShell cmdlet. You can spot this by their null values in the respective figure, which is one of the 4 incarnations of a dynamic type, as seen above. As you know Microsoft Azure has different Azure Regions available around the world. Enjoy unlimited access on 5500+ Hand Picked Quality Video Courses. At the time of this writing Sep 2020 the referenced article doesnt explicitly tell about this known limitation. Note that the row_number function (described here) is 1-based.| extend rn=row_number()| where rn>3000. foreach ($VM in $VMs) { In the final Powershell code well eliminate this column from the output. Q: Can an additional IP configuration be added to an existing vmNic while the parent VM is running?A: Yes. {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). The query well attempt to run is below: The output however indicates theres an error: Fixing this is straightforward, as the error message tells explicitly what to do*. //Get all the VMs information For more detailed help with specific command-line switches and options, you can use the Get-Help command. According to Microsofts documentation, ARG is a service in Azure that is designed to extend Azure Resource Management by providing efficient and performant resource exploration with the ability to query at scale across a given set of subscriptions[]. 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. Once you connect to Azure with the Connect-AzAccount cmdlet, you can use the other cmdlets in the Az PowerShell module. Notice below that in the details of the only result returned corresponding to our VM theres only the id of the vmNic. Is it null?A: Once a vmNic is disconnected from the VM its attached to, its parent VM id becomes null. try To understand, we need to take a closer look at the join operator and how it works. +1. Well explore both these legacy options in the non-ARG Powershell and non-ARG Azure CLI sections later.Azure Resource Manager can be used as well, but it has its own limitations which will be discussed in the next section that doesnt make it the best approach.What well be using, and discussing at length in this article, is Azure Resource Graph (ARG). Well use the VM table (figure 22) as the left (outer) table, and the vmNic table (figure 21) as the right (inner) table. Lets do something about the public IPs, so the real addresses are shown, instead of just the id. Although this will occur less than in Powershell, I dont know what exactly causes this, but Ill update the article when I find out. Without Azure Resource Graph (ARG), theres the Get-AzVM cmdlet. To fix this, grant yourself access (Owner permission will do) to at least one Azure subscription. The output is below: Copy the tenant domain and paste it in the following commands. So we can only have a single private IP address for the classic VMs. So instead of just one row as the result of the query, well have 2. You can actually see these headers back in picture 34. Important: please note that this section looked specifically into non-ARG Azure CLI commands for retrieving the private and public IPs for Azure VMs. Using the numeric example here, the rolling window starts at index 3000 and spans for 1000 rows. Example: The below cmdlet will show you the list of Azure virtual machine properties under the Demo123 resource group. The outer one will iterate through the subscription batches, while the inner one handles the pagination of Search-AzGraphs result set. The extension resource-graph currently in preview as of Sep 2020 is needed (Cloud Shell will prompt you to install this automatically), and then you can easily run the ARM query (in listing 20) using az graph query -q "", with the same lightning speed. 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 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). How to list the Azure VMs from the Availability set using PowerShell? We can easily make this run asynchronously, by having just a single operator added. There are also Powershell scripts around, but they take too long or provide incomplete information. Why are non-Western countries siding with China in the UN? Consider if one or multiple VMs get deleted when the set of queries is running, in the middle of pagination. PS C:\> az vm list -otable. Semicolons arent used in any of the queries in this article, therefore each one is a single query statement. 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. Bonus points, ARG also has Powershell and Azure CLI support. 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. And our goal is to come up with a Kusto query that retrieves each VMs name, its list of all private IPs, and its list of all public IPs. Q: I would like to see what Search-AzGraph is actually doing behind the covers. 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: I always get prompted to enter a Context when using Select-AzSubscription -Name . Note that the problem cant be fixed by serializing (eg via sorting) the results, neither by keeping the id in the result set. Duress at instant speed in response to Counterspell. 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. 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. Lets also write the output to a file, and make sure this file is removed in the beginning, if it exists. Heres a basic query ran against a test subscription with only one VM: Lets look next at the language used to write the ARG queries. What went wrong? 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. But double-checking with Microsoft Support turned out that this isnt the case. 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). But if one looks at the schema, it would appear that that is already the case: A: Ive gotten in touch with Microsoft Support, and the verbatim answer was that any value extracted from a dynamic column has a type of dynamic. The cmdlet will be scoped to the current subscription batch, using the -Subscription parameter, which takes as input an array. $Subscriptions = Get-AzureRmSubscription | Where-Object { $_.Name -in ("Prod", "Dev") } How many such matches do we have? In this context, & makes sure that the commands linked by it run one after another, as described here. Paste it in the final PowerShell code well eliminate this column from the output stands.
