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

1-2 Fabric Watch User’s Guide

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.

Fabric Watch User’s Guide 1-3
Introducing Fabric Watch 1
Figure 1-1 shows a typical example of an error counter with a temperature range threshold.
Figure 1-1 Example of Range Threshold: Temperature (Celsius)
Rising/Falling Threshold
A rising/falling threshold tracks whether an element is on the desired side of a boundary. It includes
an upper and lower boundary, and the buffer zones are always zero. Events can be selected for
transitions between the boundaries. Rising/falling thresholds are typically used for rate based
counters. Rate based counters are all counters with a time base set to something other than “none”,
this includes the TX Perf and RX Perf counters.

1-4 Fabric Watch User’s Guide
Introducing Fabric Watch
1
Figure 1-2 shows a typical example of an error counter with a rising/falling threshold.
Figure 1-2 Example of Rising/Falling Threshold: Error Rate
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.
Note: The change monitor counter value displayed is the cumulative count (historical count) and
not the delta value from the previous triggered value.
An illustration is not provided because change monitor thresholds do not include boundaries.

Using Fabric Watch
This chapter provides the following information:
•Overview on page 2-1
•User Interfaces on page 2-1
•Profiles on page 2-2
•Classes on page 2-3
•Threshold Naming Conventions on page 2-7
•Events on page 2-7
•Alarms on page 2-8
•Configuring Thresholds and Alarms on page 2-9
Overview
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
Use either Web Tools, telnet interface, an SNMP-based enterprise manager, or the configuration
file to view and modify Fabric Watch settings.
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.
Refer to the Web Tools User’s Guide for information on using Web Tools.

2-2 Fabric Watch User’s Guide
Using Fabric Watch

Telnet Interface
You can do the following using a telnet interface:
• Query fabric and switch events through the telnet command fwShow.
• Query and modify threshold and alarm configurations. Use the telnet command fwConfigure
to view the default and customized settings.
• 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 do the
following:
• 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 it 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 the switches in the fabric.
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
Each Fabric Watch profile contains a unique threshold and alarm settings. Current profiles are
divided into:
•debug
•workgroup errlog
•workgroup snmp
•enterprise errlog
•enterprise snmp
In addition, a Fabric Watch profile specific to yourenvironment can be downloaded to the switch to
customize the configuration.
The default information is always preserved. After loading the profile, you can specify whether the
default or the customized profile information is used.

Fabric Watch User’s Guide 2-3
Using Fabric Watch 2
A profile may contain the following information:
•Threshold values:
-Unit string
-Time base
-Lower boundary
-Upper boundary
-Buffer size
•Alarm values
-Change
-Exceed
-Below
-Above
-In-between
-Behavior type
Classes
Fabric and switch elements are organized into classes (also known as Agents), which are groupings
of closely related elements. The major classes are:
Fabric Monitors key fabric resources, such as fabric reconfiguration,
zoning changes, new fabric logins
Environmental Monitors switch environment functions, such as temperature,
power supply, fan status

Using Fabric Watch 2
Threshold Naming Conventions
All threshold names consist of the following three items, with no separators:
• Abbreviation for the class name (alpha characters, lower case), as follows:
Class Abbreviation
Fabric fabric
Environment env
Port port
E_Port eport
F/FL_Port (Optical) fopport
GBIC gbic
ALPA alpa
End-to-End ee
Filter flt
• Abbreviation for the area name (alpha characters, title case). For example, “Temp” for the
Temperature area.
• Index number for the number of the item within the series. Consists of three numbers, for
example: 000 for the first port, 001 for the next, etc. Index numbers for the Fabric, Port, E_Port,
F/FL_Port (Optical), and GBIC classes begin with 000, and index numbers for the Environment
class begin with 001.
Example of a Threshold Name:
The threshold corresponding to the first thermometer in the switch is in the Environment class,
Temperature area, and is therefore named envTemp001.
Events
An event is generated each time a boundary, as defined by the threshold, is crossed. Boundaries are
not inclusive, so events are generated only when a boundary is exceeded, not when the monitored
value has only reached them. If the event has an assigned alarm, an alarm is also generated. The
alarm can be designated as an SNMP trap, an entry in the switch error log, locking of the port log,
or a combination of these options.
When an item such as an E_Port, F/FL_Port (optical), Smart SFP, fan, or power supply is removed,
Fabric Watch may raise an event (such as a below event), then the threshold is hidden and disabled.
When an item is added, the threshold is displayed and enabled, and Fabric Watch may raise an
event.
Event policies control the generation of events, and can be configured for either triggered events or
continuous events.
Triggered Events
A triggered event results in a single event when a boundary is exceeded. The event is not generated
again until the threshold value has returned within the boundaries and then once again exceeded
them. For example, if the switch temperature exceeds the upper boundary, a triggered event is
generated at the point the boundary is crossed, but is not repeated while the temperature remains
above the upper boundary.

2-8 Fabric Watch User’s Guide
Using Fabric Watch
2
The following events can be generated as triggered events:
Started No alarm is generated.
Below Counter is below the lower boundary. Must be preceded by a start, above, or
in-between event.
Above Counter is above the upper boundary. Must be preceded by a start, below, or
in-between event.
Exceeded Counter is below the lower boundary or above the upper boundary. Accompanies
a below or above event.
Changed Counter value has changed.
In-between Counter falls below the upper boundary minus buffer, or rises above the lower
boundary plus buffer. Must be preceded by an above or below event. If the buffer
is set to zero, this event is suppressed.
Continuous Events
Acontinuous event results in an event at each time interval from when the boundary is initially
exceeded until the threshold value has returned within the boundaries. For example, if port
utilization is above the upper boundary, a new event is generated at each behavior interval until
utilization falls below the upper boundary. The following events can be generated as continuous
events:
Started No alarm is generated.
Below Counter is below the lower boundary.
Above Counter is above the upper boundary.
Exceeded Counter is below the lower boundary or above the upper boundary.
Accompanies a below or above event.
Changed Counter value has changed.
Alarms
Each event can generate one or more alarms. Fabric Watch supports the following types of alarms:
•SNMP trap
•Switch event log entry
•Locking of the port log
•Email
SNMP Trap
The following information is forwarded to an SNMP management station:
•Name of the element
•Class, area, and index of the threshold
•Type of event generated
•Element value
