Fabric Watch is a real-time health monitoring service that proactively monitors the health of the switches and fabric and performance settings. Fabric Watch enables each switch to monitor the SAN for potential faults and automatically alert network managers to problems before they become failures. Fabric Watch tracks a variety of SAN fabric elements, events and counters. Monitoring fabric-wide events, ports, SFPs and environmental parameters permits early fault detection and isolation as well as performance measurement. Benefits include improved high availability from proactive notification, detailed information that can be used to conduct root cause analysis and reduced troubleshooting time.
