Nutanix NCP-EUC Exam With Confidence Using Practice Dumps

Capacity Runway in Prism Central calculates the "Runway" (time remaining before resource exhaustion) based on the consumption of User VMs running on the cluster.

If a cluster is configured with Storage-Only nodes (often used for dedicated Nutanix Files/Unified Storage deployments for profiles), the AHV scheduler is configured to prevent user VMs from running on these nodes (reserving resources strictly for CVMs and storage services). Since there are no general compute workloads (User VMs) consuming CPU/RAM, the Capacity Runway algorithm has no relevant "Guest VM" consumption data to analyze, resulting in the CPU and Memory fields being blank or not displayed, while Storage capacity might still be visible.

In Nutanix Prism Central, the reporting feature allows administrators to schedule and generate custom reports. To manage storage and database capacity, Prism Central enforces a retention limit on these generated report instances.

According to the Prism Central Guide, "By default, Prism Central retains 25 instances of each report."

In the scenario described:

The administrator had 22 reports.

Over the next week (7 days), 7 new reports were generated (22 + 7 = 29 total potential instances).

Because the total (29) exceeds the hard default limit of 25, the system automatically rotated out (deleted) the 4 oldest copies to maintain the count at 25. This explains why reports are missing despite the expectation of seeing 29.

In Nutanix Prism Central, the Capacity Runway scenario provides details on the available capacity for the next 12 months based on the current usage pattern. This feature can help the administrator to plan and prepare the budget for the next fiscal year. The administrator can use this information to decide whether more resources need to be added to the Nutanix cluster or if the existing resources are sufficient.

Prism Central planning tools can help you estimate the capacity runway of your cluster by considering the storage, CPU, and memory capacity. However, you need to have at least 21 days of data from a cluster to calculate the baseline runway estimates4.
