MicrosoftHi saurabhseth ,
Thank you for posting this article. I am using azure durable function with fan-in fan-out pattern and hosted on premium app service plan. I applied rule-based scaling where Scale-out condition is Memory Percentage is greater than 70% and duration is set to 10 minutes and Scale-in condition is Memory Percentage is less than 50% and cool down time is set to 5 minutes.
Scale-out works perfectly fine for me but I am confused on how Scale-in works and how can I verify the jobs that are running on the VM2 will be successfully completed before killing/scale-in the VM2 as soon as it cools down.
For example: Function Starts with High Load and memory hits greater than 70% and it spawned a new VM and starts executing jobs there. Now if VM1 memory percentage is less than 50% it should cool down. Is there a way to check/confirm if jobs are successfully completed on VM2 which was created when load increased?
What is the definition of Stabilize metrics in below screen shot?
