In PerfStack analysis, what does node health indicate?

• A. Node health is not considered in PerfStack analysis
• B. PerfStack reports latency only
• C. Node health indicates whether the node is healthy and contributing resources to polling and alerting processes
• D. PerfStack excludes the polling engine metrics

Answer: (C)

Node health in PerfStack tells you whether the node is healthy and actively contributing resources to polling and alerting processes. This means it reflects not just if the node is up, but also if it can reliably be polled and participate in alerting, so the data you analyze is trustworthy and available for correlation across metrics. If a node is healthy, PerfStack can rely on its data to build accurate performance pictures; if it’s unhealthy, data collection and alerting may be affected, signaling potential issues with the node or its polling configuration. Choosing that node health is not considered ignores a core purpose of PerfStack, which is to assess the reliability of data sources. Saying PerfStack reports latency only misses the broader health and data-collection role of the node. Excluding the polling engine metrics would omit essential information about how the node supports data gathering and alerts, which is central to understanding overall performance trends.
