Data Analysis & Reporting Flashcards

When Prism Central displays an 'Alert' versus a 'Warning' for a performance metric, what is the key distinction in severity?

Answer: Warnings indicate approaching thresholds requiring attention; alerts indicate thresholds already breached requiring immediate action

In Prism Central, warnings flag conditions approaching critical thresholds, while alerts indicate conditions that have exceeded thresholds and require immediate intervention.

Which Nutanix API endpoint would a developer use to programmatically retrieve cluster performance metrics for integration with a third-party monitoring platform?

Answer: Prism Element REST API v2 /cluster/stats

Prism Element's REST API v2 exposes the /cluster/stats endpoint for retrieving performance statistics programmatically for external monitoring integration.

In a Nutanix cluster with RF2, if one node fails, how does this event appear in Prism's Data Resiliency reporting?

Answer: Data Resiliency Status changes to 'At Risk' — the cluster can still operate but cannot tolerate another failure

With RF2, losing one node leaves the cluster with zero fault tolerance remaining, so Prism marks Data Resiliency as 'At Risk' even though the cluster continues operating.

What is the role of 'Pulse' in Nutanix data reporting and analytics?

Answer: A telemetry service that sends anonymized cluster health and performance data to Nutanix support for proactive analysis

Nutanix Pulse is a telemetry service that collects anonymized cluster data and sends it to Nutanix, enabling proactive support and X-Ray benchmarking insights.

An administrator reviews a Prism analysis chart and notices VM 'Read Source' is predominantly showing 'SSD' rather than 'DRAM'. What does this most likely indicate?

Answer: The working set exceeds the DRAM cache capacity, falling back to the SSD tier

When reads are served from SSD rather than DRAM, it indicates the hot dataset is larger than the DRAM cache, causing cache misses that fall back to the SSD tier.

Which Nutanix report helps identify which hosts in a cluster are most heavily utilized to support workload rebalancing decisions?

Answer: Host Performance Summary Report

The Host Performance Summary Report shows per-host CPU, memory, and storage utilization, helping administrators identify hotspots for workload rebalancing.

In Nutanix Prism Central, which built-in capability allows administrators to set thresholds that trigger automated remediation actions when performance metrics are breached?

Answer: Prism Pro X-Play (Playbooks) with metric-based triggers

Prism Pro X-Play (Playbooks) enables event-driven automation where metric threshold alerts can trigger automated remediation actions such as VM scaling or ticket creation.
