How to collect a Perfstat from clustered Data ONTAP systems using the Perfstat GUI

• Perfstat is a performance and statistics data collection tool that helps in troubleshooting issues relating to storage system performance.
• This document provides information about the Perfstat 8.4 GUI tool and the procedure that should be followed to collect performance data using the tool.
• Please follow these best practices before starting:

1. Perfstat 8 is for clustered Data ONTAP only.

NOTE:

• Do not use it with 7-Mode systems.
• For 7-Mode systems, see KB for Windows and KB for Linux.

2. Run Perfstat from a physical host or a VM not associated with the cluster being collected against.
3. Do not attempt to use over a VPN connection, Perfstat is latency-sensitive and will timeout.
4. Collection host should be on the same network as the cluster, avoid a lot of network hops or latency between host and cluster.
5. The Perfstat application and related output files should only be stored on the local disk of the collection host.
