Nutanix provides extended performance metrics on multiple levels of the infrastructure, ranging from cluster-level to VM-level.

For each individual VM Nutanix has added an addtional tab in Prism where Average IO Latency, Block Size Distribution and Random vs Sequential for Reads and Writes, as well as the Read Source (DRAM/SSD/HDD) for Reads are displayed graphically.

Nutanix has also added end-to-end network performance visualization, but currently this is only available when using AHV (so no vSphere or Hyper-V support). Network Visualization is added as a separate Network page in Prism Element and Prism Central. Network Visualization extends from the VM to the virtual NICs, to physical NICs to physical switch ports.

AOS 5.5 provides enhancements to Prism Central analytics. Behavioral analytics functionality has been added to the predictive analytics functionality to provide anomaly based alerts and alarms. This is different from the existing mechanism where thresholds are used. Thresholds are typically user defined and based on tacit knowledge. Anomaly detection is valuable as it indicates when KPIs (eg. CPU utilization) have a significant deviation from the norm.

Nutanixs behavioral analytics functionality requires the Prism Pro edition which is a separate add-on subscription.
