How to get Auto scaling configuration for VMSSs

Hi Anil Kumar,

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

To fetch auto-scaling details for all your Virtual Machine Scale Sets (VMSS) in a straightforward way:

To get a list of all Virtual Machine Scale Sets, use the following query:

kql

Copy code

resources

| where type == "microsoft.compute/virtualmachinescalesets"

| project id, name, location

 To retrieve auto-scaling settings for your Virtual Machine Scale Sets, use this query:

kql

Copy code

resources

| where type == "microsoft.insights/autoscalesettings"

| project id, name, properties

To combine Virtual Machine Scale Sets with their auto-scaling settings, use this query:

kql

Copy code

let vmss = resources

| where type == "microsoft.compute/virtualmachinescalesets"

| project vmssId = id, vmssName = name;

let autoscale = resources

| where type == "microsoft.insights/autoscalesettings"

| project autoscaleId = id, autoscaleName = name, autoscaleProperties = properties;

vmss

| join kind=leftouter (autoscale) on $left.vmssId == $right.autoscaleId

| project vmssId, vmssName, autoscaleName, autoscaleProperties

Run the VMSS query to list all scale sets, the auto-scaling query to get scaling settings, and combine them to match each VMSS with its scaling configuration.

If Insights is not enabled, Some VMSSs may not have auto-scaling data, and ensure you have the necessary permissions to access both VMSS and auto-scaling information.
