Introducing Fabric Watch
This chapter provides the following information:
•Overview on page 1-1
•Threshold Behavior Models on page 1-2
Overview
Fabric Watch is used by SAN managers to monitor key fabric and switch elements, making it easy
to quickly identify and escalate potential problems. It monitors each element for out-of-boundary
values or counters and provides notification when any exceed the defined boundaries. The SAN
manager can configure which elements, such as error, status, and performance counters within a
switch, are monitored.
Fabric Watch runs on switches with Fabric OS version version 3.0.1b or later. Fabric Watchcan be
accessed through:
•Web Tools
•A telnet interface
•A Simple Network Management Protocol (SNMP) -based enterprise manager
•By modifying and uploading the Fabric Watch configuration file to the switch.
Fabric Watch monitors the following elements:
•Fabric events (such as topology reconfigurations, zone changes)
•Switch environment (fans, power supplies, and temperature)
•Ports (state changes, errors, and performance)
•SFP Units
With Fabric Watch installed, each switch continuously monitors error and performance counters
against a set of defined ranges. This and other information specific to each monitored element is
made available by Fabric Watch for viewing and, in some cases, modification. This set of
information about each element is called a threshold, and the upper and lower limits of the defined
ranges are called boundaries.
If conditions break out of acceptable ranges, an event is considered to have occurred, and one or
more of the following alarms (reporting mechanisms) are generated if configured for the relevant
threshold:
•SNMP trap
•Entry in the switch event log
•Locking of the port log to preserve the relevant information

Threshold Behavior Models
The behavior models for thresholds are:
•Range
•Rising/falling
•Change monitor
Range Threshold
A range threshold tracks whether a fabric element is within a specified range. It includes a
minimum and maximum boundary for the area, with buffer zones to prevent repeated events due to
oscillation of the value over a threshold boundary. If the value exceeds the low or high threshold
boundary, an event is generated. Fabric Watch can also generate events while the value is outside
the limits or when it re-enters the prescribed range.
