Microsoft Azure Virtual Machine Scale Sets (VMSS) is a service in Microsoft Azure that allows users to deploy and manage a group of identical virtual machines (VMs) as a scalable set. VMSS is designed to help you build and manage large-scale, high-availability applications with ease. Monitoring Microsoft Azure Virtual Machine Scale Sets is crucial to ensure the performance, availability, and reliability of your applications that use the same. Use Applications Manager's Azure Virtual Machine Scale Sets Monitoring tool to monitor your Virtual Machine Scale Sets instances and their underlying infrastructure with ease.
