Fabric Watch classes, areas, and elements

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 Resource class and Environment class areas and actions are configured using the
sysMonitor command. The FRU class actions are configured using the fwFruCfg command
describes the classes into which Fabric Watch groups all switch and fabric elements.
Fabric Watch classes
Description
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.
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.
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.
Serves as a tuning tool. The Performance Monitor class groups areas that track the
source and destination of traffic. Use the Performance Monitor class thresholds
and notifications to determine traffic load and flow and to reallocate resources
appropriately.
The Performance Monitor class is divided into the following areas: , EE (end-to-end)
Performance Monitor, and Filter Performance Monitor.
Note: Performance Monitoring is not supported on VE_Ports, EX_Ports, and
VEX _Ports.
Configure the Performance class using the thConfig command.
