Brocade Fabric Watch Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 32)

The Resource class and Environment class areas and actions are configured using the sysMonitor
command. The FRU class actions are configured using the fwFruCfg command
Elements
Fabric Watch defines an element as any fabric or switch component that the software monitors. Within
each area, the number of elements is equivalent to the number of components being monitored. For
instance, on a 64-port switch, each area of the Port class includes 64 elements.
Each element contains information pertaining to the description suggested by the area. To continue
the Ports example, each element in the Invalid Transmission Words area of the Ports class would
contain exactly 64 ports, each of which would contain the number of times invalid words had been
received by the port over the last time interval. Each of these elements maps to an index number, so
that all elements can be identified in terms of class, area, and index number. As an example, the
monitoring of the temperature sensor with an index of 1 can be viewed by accessing the first
temperature sensor within the temperature area of the environment class.
Subclasses are a minor exception to the preceding mapping rule. Subclasses, such as E_Ports,
contain areas with elements equivalent to the number of valid entries. Within the same example used
thus far in this section, in a 64-port switch in which eight ports are connected to another switch, each
area within the E_Port class would contain eight elements.
Each area of a subclass with defined thresholds will act in addition to the settings applied to the
element through the parent class. Assignment of elements to subclasses does not need to be
performed by a network administrator. These assignments are seamlessly made through automated
detection algorithms.
The table below describes the classes into which Fabric Watch groups all switch and fabric elements.
Fabric Watch classes TABLE 1
Class Description
Environment Includes information about the physical environment in which the switch resides and the
internal environment of the switch. For example, an Environment-class alarm alerts you to
problems or potential problems with temperature.
Configure the Environment class using the sysMonitor command.
Fabric Groups areas of potential problems arising between devices, including interswitch link (ISL)
details, zoning, and traffic. A Fabric-class alarm alerts you to problems or potential problems
with interconnectivity.
Configure the Fabric class using the thConfig command.
Field Replaceable
Unit (FRU) Monitors the status of FRUs and provides an alert when a part replacement is needed. This
class monitors states, not thresholds.
Configure the FRU class using the fwFruCfg command.
