Overview
Brocade Brocade Fabric WatchTM 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 SilkWorm switch, are monitored.
Brocade Fabric WatchTM is an optionally licensed product that runs on SilkWorm 2000 series
switches and above with Brocades Fabric OS™ version v3.0. Brocade Fabric WatchTM can be
accessed through:
•
•
•
•
Brocade Web Tools
A telnet interface
A SNMP-based enterprise manager
By modifying and uploading the Brocade Fabric WatchTM configuration file to the switch.
Brocade Fabric WatchTM 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)
GBICs (for switches equipped with SMART GBICs.
Example: the Finiasr SMART GBIC FTR-8519-3).
With Brocade Fabric WatchTM 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 Brocade Fabric WatchTM 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

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.
1-2
Fabric Watch User’s Guide

Introducing Brocade Fabric Watch
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.
Fabric Watch User’s Guide
1-3

Introducing Brocade Fabric Watch
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.

Each switch running Fabric Watch must have a Fabric Watch license installed on it. A license may
have been installed in the switch at the factory. If not, contact your switch supplier to obtain a
license key.
Fabric Watch requires a SilkWorm 2000 series switch or above running Brocade’s Fabric OSTM
3.0. A Fabric Watch license can be installed either using telnet commands or through Brocade Web
ToolsTM
.
Installing through Telnet
To install Fabric Watch using telnet commands perform the following steps:
1. Log onto the switch by telnet (refer to Brocade Fabric OS User’s Guide for details), using an
account that has administrative privileges.
2. To determine whether a Fabric Watch license is already installed on the switch, type
licenseShowon the telnet command line.
A list displays all the licenses currently installed on the switch.
Example:
admin> licenseShow
1A1AaAaaaAAAA1a:
Release v3.0
Web license
Zoning license
SES license
QuickLoop license
3. Enter the following on the command line:
licenseAdd “key”
where “key” is the license key provided to you, surrounded by double quotes. The license key
is case sensitive and must be entered exactly as given.

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 the telnet command
fwConfigure to view the default and customized settings.
• Upload and download the configuration file through the commands configUploadand
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 Brocade Web ToolsTM (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 fwConfigReloadto 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 your environment can be downloaded to the switch to
customize the configuration.

Using Fabric Watch
Several customized profiles for Fabric Watch are available at the following website:
Each profile is for a different purpose, and contains only the configuration information that is
different from the default configuration.
The intention is to have distinct configuration setting for enterprise SAN and a workgroup SAN’s
are left for individual user’s.
The default information is always preserved. After loading the profile, you can specify whether the
default or the profile information is used.
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

Using Fabric Watch
• 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), F/FL_Port (Copper), 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), F/FL_Port (copper), FINISAR Smart GBIC,
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.
The following events can be generated as triggered events:
Started
Below
No alarm is generated.
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.
3-8
Fabric Watch User’s Guide

Using Fabric Watch
Continuous Events
A continuous 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
Below
No alarm is generated.
Counter is below the lower boundary.
Counter is above the upper boundary.
Above
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
RAN
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
New state of element
Error Log Entry
The internal error log maintains a record of the event, up to a maximum of 64 entries. If configured
to do so, error log entries are forwarded to the SYSLOGD facility.
Locking the Port Log
Locking the Port Log freezes the switch port log to retain detail information about a problem. It is
typically used in conjunction with the error log entry.

Using Fabric Watch
RAN
RAJ sends alarm messages to the remote agent proxy server.
Note: The RAN alert is only available if the optional Fabric Access license has been purchased
and turned on.
Email Alert
The Email Alert sends alarms to the corresponding email addresses at run time. The configured
email address applies to all areas within a class. See fwMailCfg in the Fabric OS Reference Guide.
Note: This alert only works with firmware images that supports Web Tools.
Note: Whenever the switch is fastbooted or rebooted the Email alert is disabled. The Email Alert
must be reset after the switch is fastbooted or rebooted.
Configuring Thresholds and Alarms
The configuration of thresholds and alarms can be divided into two categories: threshold values and
threshold area values.
Note: Timebase changes to thresholds in Env and GBIC agents are disabled. Non-factory
timebase settings in configuration files for both of these thresholds will not have any effect.
The factory timebase will be used.
Threshold Values
Threshold values apply to the specific threshold. They are not stored in the configuration file, and
return to the default values if the switch is rebooted. The following threshold values can be
modified:
Status
Can be enabled or disabled. Enabled by default.
Behavior type
Allows setting of the event policy to triggered or continuous. Set to
triggered by default.
Behavior interval
The interval between the same type of alarm. Applies only to
continuous events. The default interval is 1 second.

Using Fabric Watch
Threshold Area Values
Threshold area values include boundaries and alarms, and apply to all the thresholds within an area.
Changes are stored in the configuration file.
Boundaries
The following boundary information can be modified:
Unit string
Represents unit value. Only the default unit strings are supported by
Fabric Watch.
Time base
Time period within which a specified event is measured. Can be
from one second to one day. Shorter time periods are more sensitive
to fluctuations and therefore will provide more detailed
information.
Note: The Time base boundary can only be modified through a
telnet command. The Time base bounder does not apply to
the:
- Transmit performance area
- Receive performance area
- Filter class
Low boundary
High boundary
Buffer size
Minimum value. An event is generated if the element value falls
below this boundary.
Maximum value. An event is generated if the element value rises
above this boundary.
Size of buffer set up to decrease generation of in-between events
due to oscillation of the element value over a boundary.
Alarms
The following alarms can be added or deleted:
ERRLOG
Logs errors to switch. If configured properly, sends message to
syslog on daemon.
SNMP-TRAP
Sends trap to SNMP agent.
PORT-LOG-LOCK
Freezes port log to preserve log information generated at time of
event, for diagnostic purposes.
RAN
Sends alarm messages to remote agent.
Note: The RAN alert is only available if the optional Fabric Access
license has been purchased and turned on.
Email Alert
Sends alarm messages to the corresponding mail address.
