Data Analysis & Reporting Flashcards

What does the Nutanix 'Data Resiliency Status' widget in Prism Central indicate when it shows a degraded state?

Answer: One or more nodes or disks have failed, reducing fault tolerance

A degraded Data Resiliency Status means a hardware failure has reduced the cluster's ability to tolerate additional failures without data loss.

In Nutanix Prism, which analysis view allows an administrator to compare the performance of multiple VMs on a single chart simultaneously?

Answer: VM Performance Comparison Chart in Analysis Dashboard

The Analysis Dashboard in Prism allows overlaying multiple VM performance metrics on a single chart for side-by-side comparison.

An administrator exports a Prism Central report and finds that CPU usage is shown as a percentage of what resource baseline?

Answer: The VM's vCPU allocation

VM CPU usage in Prism is reported as a percentage of the VM's allocated vCPUs, not the total cluster or host CPU.

Which Nutanix feature uses machine learning to establish baseline behavior and alert on deviations in VM performance metrics?

Answer: Prism Pro Anomaly Detection

Prism Pro's Anomaly Detection uses machine learning to learn normal performance baselines and alert administrators when metrics deviate significantly.

When analyzing Nutanix storage performance reports, what does a high 'avg.io_size' value typically suggest about the workload?

Answer: The workload involves large sequential transfers such as backups or data streams

A high average I/O size indicates large sequential I/O patterns, typical of backup, streaming, or bulk data transfer workloads.

In Nutanix capacity planning reports, what is the significance of separate 'Storage Tier' runway values for SSD and HDD?

Answer: They indicate when each storage tier will be full independently, since hot and cold data fill at different rates

SSD and HDD tiers fill at different rates because hot data resides on SSD while cold data moves to HDD, so each tier has its own capacity runway.

What Nutanix CLI command is used to retrieve a summary of cluster storage statistics including capacity and usage from the command line?

Answer: ncli storagepool list

The `ncli storagepool list` command provides a summary of storage pools including total capacity, used space, and free space.
