If you currently use the deprecated hyperv_vms_guestinfos.ps1 plug-in, you must replace it with the new hyperv_host.ps1 plug-in after upgrading. This new Checkmk agent plug-in replaces the old one and provides more detailed and useful information about your Hyper-V virtual machines, helping you monitor their status and resource usage more effectively.

The new plug-in delivers comprehensive VM data, including:

  • General information such as the VM name and machine generation
  • The most recent and oldest checkpoints used by the VM
  • Usage status of the guest integration services
  • Configured RAM details, including start, minimum, maximum, and currently assigned RAM, as well as demand if available
  • VHD(X) size and its actual storage consumption on the Hyper-V host
  • Network interfaces and their assignment to virtual switches (virtual network adapters connected to virtual networks)

To start using this enhanced monitoring, deploy the plug-in via the Agent Bakery rule set "Hyper-V" or manually place the hyperv_host.ps1 file in the %SystemDrive%\ProgramData\checkmk\agent\plugins folder on the Windows host.
