How is performance monitored in NetApp ONTAP?

• A. Through OnCommand tools (or Unified Manager), performance charts, and perfstat logs.
• B. Through manual observation only.
• C. By automatic daily emails with no tools.
• D. By third-party cloud metrics only.

Answer: (A)

ONTAP performance monitoring relies on a combination of measurement collection, visualization, and centralized management provided by the OnCommand tools. Perfstat collects detailed performance statistics directly from the storage systems, giving you granular data on IOPS, latency, throughput, and queue depth. Those statistics are then shown in performance charts in the ONTAP UI or in Unified Manager, providing real-time views and historical trends to help with troubleshooting and capacity planning. OnCommand tools like Unified Manager offer centralized monitoring, alerting, and reporting across multiple clusters, making it easier to spot issues and compare performance over time. This approach gives both the raw data and the accessible insight you need, rather than relying on hand-measured observations, generic emails, or metrics from outside sources that don’t include ONTAP’s internal measurements.
