@Deepudev13 Below is the documentation for automatic instance repairs for Azure virtual machine scale sets (which includes a link for information on both Load balancer health probes and Application Health extension although only one of these can be used at a time):

https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-automatic-instance-repairs

Enable application health monitoring for scale set

The scale set should have application health monitoring for instances enabled. This can be done using either Application Health extension or Load balancer health probes. Only one of these can be enabled at a time. The application health extension or the load balancer probes ping the application endpoint configured on virtual machine instances to determine the application health status. This health status is used by the scale set orchestrator to monitor instance health and perform repairs when required.

If you'd like additional assistance setting up your VMSS, reach out on the Microsoft Q&A forums:
