Hyper-V is a hardware virtualization platform used to create and run virtual machines on Windows host systems. It allocates resources from the physical hosts it runs on to the virtual machines it creates, but if those resources are spread too thin, virtual machines may encounter slow performance and startup failures. With Datadog's integration, you can monitor the health of every layer of your Hyper-V stack, including physical hosts, virtual machines, and applications running on them. You can set up alerts to get notified when a host's available memory drops below a certain threshold or when a host is overloaded, allowing you to avoid excessive paging and prevent performance impairment. Datadog provides deep visibility into CPU workloads across physical and virtual machines, enabling you to graph real-time CPU usage across your Hyper-V infrastructure and set up alerts to notify you of potential issues. Additionally, Datadog's Live Process monitoring provides a granular view of process-level resource usage across each of your Hyper-V virtual machines, updated every two seconds, allowing you to monitor and optimize the performance of your Hyper-V environment alongside other parts of your Windows stack.
