Microsoft Hyper-V Server Monitoring


Hyper-V - An Overview

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.

Creating a new Hyper-V monitor

Follow the steps given below to create a new Microsoft Hyper-V Server monitor:

  1. Click the New Monitor drop-down link menu.
  2. Select Hyper-V Server under Virtualization category. This action will load the Add Monitor screen.
  3. Specify the Display Name of the Hyper-V server.
  4. Enter the Host Name or IP Address of the host where the Hyper-V server is running.
  5. Enter the credential details like user name and password for authentication, or select the required credentials from the Credential Manager list by enabling the Select from Credential list option.
  6. Select the Monitor Performance Metrics of Virtual Machines option if you want Applications Manager to collect performance metrics of VMs of this server.
  7. Select the Version of your Microsoft Hyper-V Server from the drop-down menu (2008, 2012, 2016 or 2019).
  8. Select the VM Discovery option. Available options are Do not discover, Discover VM but do not monitor metrics, and Discover and Monitor VM metrics.
  9. Specify the Polling Interval in minutes.
  10. If you are adding a new monitor from an Admin Server, select a Managed Server.
  11. Select the Monitor Group with which you want to associate the Hyper-V server, from the combo box (optional). You can choose multiple groups to associate your monitor.
  12. Click Add Monitor(s). This discovers the Hyper-V server from the network and starts monitoring it.

User Permissions

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).

Firewall Requirements

If a firewall is present between Applications Manager and the Hyper-V server, open ports 135,443 and 1025 in the firewall to enable access.

Supported Versions

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.
