Monitor Microsoft Hyper-V with Datadog

Hyper-V is a hardware virtualization platform used to create and run virtual machines on Windows host systems.

If those resources are spread too thin, virtual machines may encounter slow performance and startup failures. With our new integration you can monitor the health of every layer of your Hyper-V stack: physical hosts, virtual machines, and all of the applications and services running on them.
