Preface Fabric Watch is an optionally licensed product, and requires a valid license key to function. It is supported on the SilkWorm® 3800 series of switches running Brocades Fabric OS™ v3.0. About This Guide This guide provides the following information about Fabric Watch: Chapter 1 Introducing Fabric Watch Provides an overview of Fabric Watch. Chapter 2 Installing Fabric Watch Provides instructions for installing Fabric Watch.
Information about fibre channel standards and fibre channel in general can be found on the Fibre Channel Association web site, located at: http://www.fibrechannel.com Getting Help Contact your switch supplier for technical support. This includes hardware and software support, all product repairs, and ordering of spare components.
Chapter Introducing Brocade Fabric Watch 1 This chapter provides the following information: • Overview on page 1-1 • Threshold Behavior Models on page 1-2 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.
1 Introducing Brocade Fabric Watch • • • Entry in the switch event log Locking of the port log to preserve the relevant information RAN (Remote Asynchronous Notification) Alert. Note: The RAN alert is only available if the optional Fabric Access license has been purchased and turned on. • Email Alert You can deploy Brocade Fabric WatchTM as shipped, or download a customized configuration profile from the following website: http://www.brocade.
Introducing Brocade 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.
1 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.
Chapter Installing Fabric Watch 2 This chapter provides the following information: • Installing through telenet commands 2-1 • Installing through Brocade Web ToolsTM 2-2 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.
2 Installing Fabric Watch Installing through Brocade Web Tools To install Fabric Watch using Web Tools, perform the following steps: 1. Launch the web browser, enter the switch name or IP address in the Location/Address field (for example: http://111.222.33.1), and press Enter. Brocade Web ToolsTM launches, displaying the Fabric View. 2. Click the Admin button on the relevant switch panel. The logon window displays. 3. Enter a logon name and password with administrative privileges and press Enter.

3 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 configUpload and configDownload.
Using Fabric Watch 3 Several customized profiles for Fabric Watch are available at the following website: http://www.brocade.com/support/mibs_rsh/index.jhtml 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.
3 Using Fabric Watch Monitors ALPA devices of Loop ports (currently CRC error of ALPA device only). End-to-End 1 - Monitors transmitting performance predefined by the SID-DID pair. Configurable with either telnet commands or Web Tools at run time. 2 - Monitors receiving performance predefined by the SID-DID pair. Configurable with either telnet commands or Web Tools at run time. 3 - Monitors CRC errors of prefedined SID-DID pair. Configurable with either telnet commands or Web Tools at run time.
Using Fabric Watch Class Area Description Fabric Zoning changes Monitors changes to currently enabled zoning configuration. Fabric to QuickLoop changes Monitors ports to detect changes from fabric to QuickLoop or QuickLoop to fabric. Fabric logins Monitors number of host device fabric logins (flogi). GBIC change Monitors insertion/removal of GBIC. Temperature Monitors switch temperature. Fan Monitors operation of switch fans. Power supply Monitors status of each power supply.
3 Using Fabric Watch Class F/FL_Port (Copper) GBIC Area Description Loss of synchronization count Monitors optical F/FL_port sync loss. Loss of signal count Monitors optical F/FL_port signal loss. Primitive sequence protocol error Monitors optical F/FL_port protocol errors. Invalid transmission word Monitors optical F/FL_port invalid words. Invalid CRC count Monitors optical F/FL_port CRC errors. Receive performance Monitors optical F/FL_port receive performance.
Using Fabric Watch Class Area Description GBIC Receiver power Monitors GBIC receiver power. Transmitter power Monitors GBIC transmitter power. Current Monitors GBIC current. ALPA CRC Counter Monitors all active ALPA devices on loop ports. End-to-End CRC - Counter Monitors CRC errors of a predefined SID-DID pair at a given port. Transmit performance Monitors transmit performance of predefined SID-DID pair at a given port.
3 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.
Using Fabric Watch 3 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 No alarm is generated. Below Counter is below the lower boundary.
3 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.
Using Fabric Watch 3 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.
