Microsoft Hyper-V is a hypervisor-based virtualization solution for x86-64 systems and an important player in the booming server virtualization space; a critical part of a working IT environment, it needs to be tracked and observed constantly to ensure zero downtime. A Hyper-V monitor helps in monitoring your Microsoft Hyper-V servers and their guest virtual machines, and ensures they are performing well at all times.
Applications Manager monitors the critical components of the Hyper-V server to detect any performance problems. The components includes processor, CPU, memory, disk, hardware, virtual & physical network, virtual storage, etc.
To monitor a Hyper-V host, the user must have ‘Administrator’ privileges to the root OS (Windows 2008 R2 and other supported Hyper-V versions).
If a firewall is present between Applications Manager and the Hyper-V server, open ports 135 and 445 in the firewall to enable access.
Versions: Hyper-V Server 2008 R2, Windows Server 2008 R2 Standard, Windows Server 2008 R2 Enterprise, Windows Server 2008 R2 Datacenter, Hyper-V Server 2012, Hyper-V Server 2016, and Hyper-V Server 2019.
