Viewing Analytics in the VAST Management System GUI - Demonstration

This video from VAST Data Customer Education provides a live demonstration of the VAST Management System (VMS) analytics GUI in action. For storage administrators and operators, this tutorial offers a practical look at how to use these powerful tools for real-time performance monitoring and effective troubleshooting on a VAST cluster. The demonstration begins with a live workload being initiated on the system, creating a sharp increase in I/O. We then use the VMS analytics to:

  • Observe real-time performance metrics, including IOPS and bandwidth.

  • Identify a performance bottleneck by seeing that a single CNode is handling the bulk of the workload.

The core of the demonstration focuses on the Data Flow tool. This intuitive feature allows for a step-by-step tracing of the I/O, providing a clear path from the client to the storage. We show how to:

  • Pinpoint the specific user and host generating the workload.

  • Trace the data flow through a particular VIP pool.

  • Identify the exact CNode handling the traffic.

  • Determine the specific view (file system) where the I/O is occurring.

This live walkthrough showcases how VMS analytics simplifies the process of identifying “noisy neighbors” and performance hot spots, providing the granular visibility needed to quickly diagnose and resolve storage networking issues. This tutorial is designed to equip VAST Data operators with the skills to effectively leverage the VMS GUI for proactive performance management and data-driven troubleshooting.
