 ### Monitor application health
 Application health monitoring allows your application to provide Azure with a heartbeat to determine whether your application is healthy or unhealthy. Azure can automatically replace VM instances that are unhealthy. For Flexible scale set instances, you must install and configure the Application Health Extension on the virtual machine. For Uniform scale set instances, you can use either the Application Health Extension, or measure health with an Azure Load Balancer Custom Health Probe.
 
 ### List scale sets VM API changes
-Virtual Machine Scale Sets allows you to list the instances that belong to the scale set. With Flexible orchestration, the list Virtual Machine Scale Sets VM command provides a list of scale sets VM IDs. You can then call the GET Virtual Machine Scale Sets VM commands to get more details on how the scale set is working with the VM instance. To get the full details of the VM, use the standard GET VM commands or [Azure Resource Graph](../governance/resource-graph/overview.md).
