Which NetApp utility would you use to collect FC SAN performance data for analysis?

• A. perfstat
• B. poststat
• C. prestat
• D. sio_ntap.exe

Answer: (A)

Perfstat is NetApp’s built-in tool for gathering performance statistics from the ONTAP system, including Fibre Channel SAN data. It collects I/O metrics such as throughput, latency, IOPS, and port utilization across disks, interfaces, and FC paths, producing data you can analyze to troubleshoot or trend SAN performance. Prestat and poststat are ancillary steps used to prepare and summarize data around the main collection, but the actual data capture for FC SAN performance is performed by perfstat. The other option listed is not a standard NetApp data-collection tool for FC SAN performance.
