INTRODUCING FABRIC WATCH
Fabric Watch allows the SAN manager to monitor key fabric and switch
elements, making it easy to quickly identify and escalate potential
problems. The SAN manager 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 a2.4.1or later, and
can be accessed through Web Tools, a Telnet interface, an SNMP-based
enterprise manager, or by modifying and uploading the Fabric Watch
configuration file to the switch.
Fabric Watch monitors the following elements:
•Fabric events (such as topology reconfigurations and zone changes)
•Switch environment (fans, power supplies, and temperature)
•Ports (state changes, errors, and performance)
•GBICs (for switches equipped with Finisar SMART GBICs
FTR-8519-3)
With Fabric Watch, each switch continuously monitors error and
performance counters against a set of defined ranges. This and other

12 Fabric Watch User’s Guide
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 alarms (reporting mechanisms) are generated if
configured for the relevant threshold. There are three types of alarms:
•SNMP trap
•Entry in the switch event log
•Locking of the port log to preserve the relevant information
Threshold Behavior Models
There are three behavior models for thresholds: range, rising/falling, and
change monitor.
Range Threshold
A range threshold tracks whether a fabric element is within a specified
range. This threshold 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. A range threshold can also
generate events while the value is outside the limits or when it re-enters the
prescribed range.

Introducing Fabric Watch 13
Temperature as an example of a range threshold is illustrated in Figure 1.
Rising/Falling Threshold
A rising/falling threshold tracks whether an element is on the desired side
of a boundary. This threshold includes an upper and lower boundary, and
the buffer zones are always 0. Events can be selected for transitions
between the boundaries. Rising/falling thresholds are typically used for
rate-based counters.

14 Fabric Watch User’s Guide
An error counter as a rising/falling threshold is illustrated in Figure 2.
Change Monitor Threshold
A change monitor threshold generates events whenever a counter value
changes, regardless of the type of change. This type of threshold is usually
used to indicate state changes, such as zoning changes. Because change
monitor thresholds include no boundaries, no illustration is provided.

USING FABRIC WATCH
Fabric Watch provides the following information about each
out-of-boundary condition discovered:
•Name of threshold
•Current value of element counter
•Unit of measurement (for example, degrees Celsius, RPM, or unit
of time)
•Time base for counter, used to compute rate of change (for example,
events per minute)
•Historical information about the last alarmed event generated
User Interfaces
You can view and modify Fabric Watch settings through Web Tools, the
Telnet interface, an SNMP-based enterprise manager, or the configuration
file.

16 Fabric Watch User’s Guide
Web Tools
Through Web Tools, you can:
•View fabric and switch events through the fabric-wide Event View.
•View and modify threshold and alarm configurations through the
Fabric Watch View.
•Upload and download the configuration file through the Config Admin
tab in the Switch Admin window.
Telnet Interface
Through a Telnet interface you can:
•Query fabric and switch events through the Telnet command fwShow.
•Query and modify threshold and alarm configurations. Both the default
and customized settings are provided by the Telnet command
fwConfigure.
•Upload and download the configuration file through the commands
configUpload and configDownload.
SNMP-Based Enterprise Managers
The Fabric Watch configuration information is stored as MIB variables,
allowing you to:
•Query the MIB variable for individual fabric and switch elements.
•Query and modify threshold and alarm configurations.
•Receive generated SNMP traps when threshold conditions are met.
Configuration File
You can view and modify the threshold and alarm configurations by
uploading the configuration file from the switch to the host, editing the files
in a text editor, then downloading the modified file back to the switch. You
can then ensure a uniform configuration throughout the fabric by
distributing the configuration file to all switches in the fabric.

Using Fabric Watch 17
The configuration file can be uploaded and downloaded through either
Web Tools (the Config Admin tab in the Switch Admin window), or the
Telnet commands configUpload and configDownload. After
downloading the file back to the switch, you must either reboot the switch
or use the Telnet command fwConfigReload to reload the configuration
file.
Profiles
Fabric Watch includes a complete set of threshold and alarm configuration
defaults. In addition, a Fabric Watch profile specific to your environment
can be downloaded to the switch to customize the configuration. Each
profile is for a different purpose, and contains only the configuration
information that is different from the default configuration. The default
information is always preserved. After loading the profile, you can specify
whether the default or the profile information is used.
A profile can contain the following information:
•Threshold values
Unit string, time base, lower boundary, upper boundary, and buffer size
•Alarm values
Change, exceed, below, above, in-between, and behavior type
Classes
Fabric and switch elements are organized into classes, which are groupings
of closely related elements. There are six major classes
•Fabric
Monitors key fabric resources, such as fabric reconfiguration, zoning
changes, and new fabric logins
•Environmental
Monitors switch environment functions, such as temperature, power
supply, and fan status

18 Fabric Watch User’s Guide
