Troubleshooting Tools and Techniques

Multiple techniques and tools are available to monitor and trouble shoot the Cisco MDS 9000 Family of
switches. These tools provide a complete, integrated, multi-level analysis solution.
Fabric Manager Server—The Cisco Fabric Manager Server provides a long-term, high level view of
storage network performance. Fabric wide performance trends can be analyzed using Performance
Manager. It provides the starting point for deeper analysis to resolve network hot-spots.
Device Manager—If a performance problem is detected with the Fabric Manager Server, use Cisco
Device Manager to view port level statistics in real-time. Details on protocols, errors, discards, byte and
frame counts are available. Samples can be taken as frequently as every 2 seconds, and values can be
viewed in text form or graphically as pie, bar, area and line changes.
