HyperV

The Technical Specifications below provide details on metrics collected by the HyperV application, how those metrics are evaluated by Longitude, and the available preconfigured reports. For additional details on the Longitude HyperV application, see the HyperV Application User Guide or contact Heroix Support.

Events

Longitude Events are generated when collected performance and availability metrics are evaluated by Longitude’s rule engine and a potential problem is detected.

The rules use best-practice thresholds, displayed below, which can be customized as needed.

Reports

Longitude reports display performance and availability metrics over time. Summary reports display average metrics across multiple devices, while detail reports drill down and present a more granular view of metrics for a selected device.
