14 Fabric Watch concepts
Areas
While classes represent large groupings of information, areas represent the information that Fabric Watch
monitors. For example, switch temperature, one of the values tracked by Fabric Watch, is an area within
the class Environment.
The tables in this section describe all of the areas monitored by Fabric Watch, organized by their
associated classes.
Environment class areas
Table 3 lists and describes the Fabric Watch areas in the Environment class.
Performance Monitor Serves as a tuning tool. Performance Monitor classes group areas
that track the source and destination of traffic. Use the Performance
Monitor class thresholds and alarms to determine traffic load and
flow and to reallocate resources appropriately.
The Performance Monitor class is divided into the areas AL_PA
Performance Monitor, EE (end-to-end) Performance Monitor, and
Filter Performance Monitor.
Port Enables you to set additional thresholds, specific to different types of
ports.
The Port class is divided into separate classes:
E_Port class—Represents ports connected to another switch.
F/FL_Port class —Represents fabric or fabric loop ports that are
made of copper or optical fiber.
Resource Monitors flash memory. It calculates the amount of flash space
consumed and compares it to a defined threshold.
Security Monitors all attempts to breach your SAN security, helping you
fine-tune your security measures.
SFP Groups areas that monitor the physical aspects of SFPs. An SFP class
alarm alerts you to a SFP malfunction fault.

Class Description
Table 3 Environment class areas
Area Description
Fan Refers to the speed of the fans inside the switch, in revolutions per
minute. It is important that the fans spin quickly enough to keep the
ambient temperature from rising to levels at which switch damage
might occur.
Power Supply Monitors whether power supplies within the switch are on, off,
present, or absent. Fabric Watch monitors power supplies to be
sure that power is always available to a switch.
Temperature Refers to the ambient temperature inside the switch, in degrees
Celsius. Temperature sensors monitor the switch in case the
temperature rises to levels at which damage to the switch might
occur.
