Hello Mahavir Saroj, the Host metrics relate to the Hyper-V session that manages the guest operating systems. They include information about the physical host’s CPU, network, and disk utilization. Host metrics give you an understanding of the overall performance and load on the VM's physical host.
On the other hand, Guest metrics pertain to the operating system and applications running inside the virtual machine. They provide visibility into the performance and health of the applications, components, and processes within the VM. Guest metrics require additional setup such as installing the Azure Monitor agent.
