Monitoring Hyper-V with New Relic provides a scalable and flexible way to analyze key metrics from virtual machines. The process involves installing the New Relic infrastructure agent on each node in the Hyper-V cluster, configuring the `config.json` file to specify which performance counters to collect, and visualizing the data using New Relic One dashboards. By integrating with WMI, New Relic can gather a wide range of metrics, including memory performance, storage performance, network performance, and CPU utilization, providing context to Hyper-V metric data when combined with other data in the platform. The solution is open and allows for customization, enabling users to build their own dashboards and applications to fit their unique needs.
