Looking for a better Hyper-V monitoring solution other than Task Manager?

After a little searching I found a tool developed by Tim Mangan called HyperV_Mon

The HyperV_Mon tool helps you to understand Performance characteristics in a Hyper-V world.

HyperV_Mon monitors physical, logical, and virtual performance information that is available when running virtual machines under Microsoft Hyper-V. The graphical display is organized to help easily understand the CPU performaces being experienced. Detailed text displays also help highlight other performance issues such as memory, paging, and I/O. Additional information is provided about virtualization “overhead” that is detected within the VMs.

You can download the install and supporting documentation here.
