Microsoft Hyper-V is a widely used virtualization tool among Windows administrators, facilitating the creation and management of virtual machines and supporting multiple operating systems. It is instrumental in building public, private, and hybrid clouds and offers features like failover clusters for redundancy. The blog post describes how to monitor Hyper-V using New Relic Infrastructure and its on-host integration (OHI) by leveraging Windows performance counters and Windows Management Instrumentation (WMI) to track key metrics. The integration involves installing the New Relic infrastructure agent and customizing configuration files to collect data from Hyper-V environments, which can then be visualized through New Relic dashboards. Additionally, the post highlights the flexibility and openness of the New Relic WMI OHI, which allows users to incorporate any necessary Hyper-V metrics into their data sets for further analysis and visualization.
