DRAFT: BROCADE CONFIDENTIAL 1 Fabric Watch overview Fabric Watch provides the following types of automatic notifications: • A continuous alarm provides a warning message whenever a threshold is breached; it continues to send alerts until the condition is corrected. For example, if a switch exceeds its temperature threshold, Fabric Watch activates an alarm at every measurement interval until the temperature returns to an acceptable level.
DRAFT: BROCADE CONFIDENTIAL Fabric Watch and Web Tools 1 Fabric Watch and Web Tools Web Tools provides a graphical user interface that can be launched from an Internet browser as an alternative to Telnet and the command line interface. You can use Web Tools to perform any of the following Fabric Watch-related operations: • • • • • • • Activate Fabric Watch. View fabric and switch events. View and modify threshold and alarm configurations with the Fabric Watch view.
DRAFT: BROCADE CONFIDENTIAL 1 Fabric Watch components Fabric Watch components Fabric Watch uses a hierarchical organization to track the network device information it monitors. There is a class, area, and element associated with every monitored behavior. Classes are the highest level in the system, subdivided into one or more areas. Areas contain one or more elements. The following sections explain this hierarchy and its application within Fabric Watch.
DRAFT: BROCADE CONFIDENTIAL Fabric Watch components TABLE 1 1 Fabric Watch classes (Continued) Class Description Port Enables you to set additional thresholds specific to different types of ports. The Port class is made up of the following classes: • E_Port class—Represents ports connected to another switch.
DRAFT: BROCADE CONFIDENTIAL 1 Fabric Watch components Fabric class areas Table 3 lists Fabric Watch areas in the Fabric class and describes each area. TABLE 3 Fabric class areas Area Description Domain ID Changes Monitors forced domain ID changes. Forced domain ID changes occur when there is a conflict of domain IDs in a single fabric and the principal switch has to assign another domain ID to a switch. Fabric Logins Activate when ports and devices initialize with the fabric.
DRAFT: BROCADE CONFIDENTIAL Fabric Watch components 1 Performance Monitor class areas Table 5 lists Fabric Watch areas in the Performance Monitor class and describes each area. TABLE 5 Performance Monitor class areas Area Indicates Customer Define Relies on performance monitor Telnet commands. For more information on this area, see the Fabric OS Command Reference. Invalid Cyclic Redundancy Checks (CRC) Errors have been detected in the Fibre Channel frame.
DRAFT: BROCADE CONFIDENTIAL 1 Fabric Watch components TABLE 6 Port class areas (Continued) Area Indicates State Changes The state of the port has changed for one of the following reasons: The port has gone offline. The port has come online. The port is testing. The port is faulty. The port has become an E_Port, EX_Port, VE_Port, or VEX_Port. The port has become an F/FL_Port. The port has segmented. The port has become a trunk port.
DRAFT: BROCADE CONFIDENTIAL Fabric Watch components TABLE 8 1 Security class areas (Continued) Area Indicates Login Violation A login violation occurs when a secure fabric detects a login failure. MS Violation An MS (Management Server) violation occurs when an access request reaches a secure switch from an unauthorized WWN (World Wide Name). The WWN appears in the ERRLOG. No FCS The switch has lost contact with the primary FCS.
DRAFT: BROCADE CONFIDENTIAL 1 Fabric Watch components TABLE 9 SFP class areas (Continued) Area Description Current The current area measures the amount of supplied current to the SFP transceiver. Current area events indicate hardware failures. Supply Voltage The supply voltage area measures the amount of voltage supplied to the SFP. If this value exceeds the threshold, the SFP is deteriorating. Elements Fabric Watch defines an element as any fabric or switch component that the software monitors.
DRAFT: BROCADE CONFIDENTIAL Event Configuration 1 Event Configuration The following area attributes are used to define and detect events in Fabric Watch: • • • • • “Event behavior types” on page 11 “Data values” on page 12 “Threshold values” on page 12 “Time bases” on page 14 “Event settings” on page 16 You can customize the information reported by Fabric Watch by configuring event behavior types, threshold values, time bases, and event settings.
DRAFT: BROCADE CONFIDENTIAL 1 Event Configuration Data values A data value represents three aspects of a fabric: counter value, measured value, or state value. Data values are updated by Fabric Watch approximately every six seconds, an interval that you cannot change. Counter value is the total number of times that a given event has occurred. For each monitored event during the time period, the value is incremented.
DRAFT: BROCADE CONFIDENTIAL Event Configuration 1 Buffer values Figure 1 shows an example in which each time a signal crosses the high limit, an event occurs. The arrows indicate the points at which the event criteria is met. In this case, there is a great deal of fluctuation. Even when the monitor is set to triggered, a number of messages are sent. FIGURE 1 Threshold monitoring You can use buffer values to reduce the occurrence of events due to data fluctuation.
DRAFT: BROCADE CONFIDENTIAL 1 Event Configuration Time bases Time bases are time periods within Fabric Watch. This configurable field impacts the comparison of sensor-based data with user-defined threshold values. Setting time base to none If you set a time base to none, Fabric Watch compares a data value against a threshold boundary level. When the absolute value of the measuring counter exceeds the threshold boundary, an event is triggered.
DRAFT: BROCADE CONFIDENTIAL Event Configuration 1 The following examples illustrate each point. Example1: Triggering an event Figure 4 shows a sample graph of data obtained by Fabric Watch (the type of data is irrelevant to the example). A high threshold of 2 is specified to trigger an event. A time base of minute is defined. An event occurs only if the rate of change in the specific interval (one minute in this example) is across the threshold boundary.
DRAFT: BROCADE CONFIDENTIAL 1 Event Configuration At the tenth sample, the rate of change is one per minute. At the fourteenth, twenty-first, and twenty-fifth sample, the rate of change remains equal to the high threshold of 2. In this case, Fabric Watch does not trigger an event even though the absolute value of the counter reaches 4, which is well above the high threshold.
DRAFT: BROCADE CONFIDENTIAL 1 Event Configuration Above event triggers Use the Above event trigger for an element that requires only high threshold monitoring. In the Above event trigger, Fabric Watch triggers an event immediately after the data value becomes greater than the high threshold. Define a buffer zone within the operational limit of an area to suppress multiple events when the counter value goes above the high threshold and fluctuates around it.
DRAFT: BROCADE CONFIDENTIAL 1 Event Configuration Changed event trigger Use the Changed event trigger for an element that requires “rate of change” monitoring. When Fabric Watch detects a change in the counter value between two sample periods (defined by the time base), it triggers an event regardless of high or low threshold settings. Figure 7 shows events generated when the data value changes. Each arrow in the figure indicates a generated event.
DRAFT: BROCADE CONFIDENTIAL Event Configuration 1 Figure 8 illustrates event notification using an In-Between event trigger. The arrow labeled 1 indicates the point at which event notification occurs. FIGURE 8 In-between event trigger Fabric Watch alarm behavior Fabric Watch alarm behavior depends on the threshold states associated with the Above, Below and Changed thresholds. Threshold states can be INFORMATIVE, IN_RANGE, and OUT_OF_RANGE.
DRAFT: BROCADE CONFIDENTIAL 1 Port persistence Port persistence The data collected in port monitoring can vary a great deal over short time periods. Therefore, the port can become a source of frequent event messages (the data can exceed the threshold range and return to a value within the threshold range). Fabric Watch uses port persistence for a port event that requires the transition of the port into a marginal status.
DRAFT: BROCADE CONFIDENTIAL 1 Notification methods Table 10 shows the default threshold boundary values and buffer sizes that have been changed for the Port class, E_Port class, and F/FL_Port class and the areas that Port Fencing supports. For a full list of default threshold boundary values and buffer sizes, refer to Table 22, Table 23, and Table 24.
DRAFT: BROCADE CONFIDENTIAL 1 Notification methods Switch event (error) log The switch event (error) log holds up to 1024 entries. This error log stores event information but does not actively send alerts. Use the errShow command to view the log. Log entries can also trigger SNMP traps if the SNMP agent is configured. When the SNMP agent is configured to a specific error message level, then error messages at that level trigger SNMP traps.
DRAFT: BROCADE CONFIDENTIAL Notification methods 1 E-mail alert E-mail alert sends information about a switch event to a specified e-mail address. E-mail alert can send information about any error from any element, area, and class. The e-mail specifies the threshold and describes the event, much like an error message. Use the fwMailCfg command to configure e-mail alerts. NOTE To send e-mail alerts, the switch must be connected to a DNS server. Use the dnsConfig command to configure DNS settings.
DRAFT: BROCADE CONFIDENTIAL 1 Switch policies Switch policies Switch policies are a series of rules that define specific states for the overall switch. Fabric OS interacts with Fabric Watch using these policies. Each rule defines the number of types of errors that transitions the overall switch state into a state that is not healthy.

Notification configuration 3 Step 6. Disable and enable thresholds by port (optional) On certain occasions, you might want to disable all port thresholds at once. For example, during an event such as an upgrade of a device or server, you might elect not to receive error messages for particular ports. When the upgrade is complete, you can show and enable disabled port thresholds.
3 Notification configuration Configuring alarm notifications When you use alarm notifications, error messages are sent to designated locations such as an error log, SNMP trap view, or e-mail. With an error log, you can log in to a particular switch to view the error messages that have been captured for that particular switch. You can parse the log file to make error message searches quicker and easier. NOTE You can enable Port Fencing only if the alarms are enabled using the fsAlarmsFilterSet command. 1.
Notification configuration 3 Port Log Lock action configuration Port Log Lock freezes in time the port log dump output if an event is triggered. See “Configuring alarm notifications” on page 44 for details about configuring port log lock actions. See Chapter 1, “Fabric Watch Concepts” for more details about port log lock. E-mail notification configuration In environments where it is critical that you are notified about errors quickly, you might want to use e-mail notifications.
3 Notification configuration 2. Type the number corresponding to the class for which the e-mail configuration should be displayed. Fabric Watch displays information such as: Mail Recipient Information ____________________________________ Email Alert = enabled Mail Recipient = sysadmin@mycompany.com The system returns to the main fwMailCfg menu. Disabling an e-mail alert 1. Type 2 in the fwMailCfg menu to disable e-mail alerts for a specific class. The Config Show menu displays. 2.
Notification configuration 3 Sending test mail 1. Type 4 in the fwMailCfg menu to test the mail configuration for a specific class. The Config Show menu displays. 2. Select a class to test. If the e-mail configuration for the class is complete, the following confirmation message displays: Email has been sent If the e-mail configuration for the class is not complete, the following error message displays: Email has not been sent.
3 Notification configuration 3. Enter the relay host IP address (example: 192.168.39.118). The following message displays: Setting 192.168.39.118 as Relay Host.. 4. Enter the Domain Name (example: Brocade.com). Displaying the relay host configuration 1. Type 6 in the fwMailCfg menu to display the relay host configuration menu. 1 2 3 4 Display Relay Host configuration Set Relay Host IP Remove Relay Host configuration Quit 2. Type 1 to display the configuration. Removing the relay host configuration 1.
3 Switch status policy configuration Switch status policy configuration The switch status policy monitors the overall status of a switch based on several contributing parameters. The policy parameter values determine how many failed or faulty units of each contributor are allowed before triggering a status change in the switch from Healthy to Marginal or Down.
3 Switch status policy configuration TABLE 13 Switch status policy monitor health factors Monitor Health factors Power Supplies Power supply thresholds detect absent or failed power supplies, and power supplies that are not in the correct slot for redundancy. When intelligent blades like the FR4-18i are in the 48000 chassis, the 48000 operates in high power mode, which means that four power supplies are required for redundancy.
FRU configuration 3 Viewing your switch status policy After you have defined and configured your switch status policy, view it with the following command: switchStatusPolicyShow The policy you defined here determines the output in the Switch Status Policy Report. See Chapter 4, “Generating Fabric Watch Reports” for more details about the Switch Status Policy Report. FRU configuration The configuration of FRUs is an exception to the procedures described thus far in this chapter.
3 Fabric Watch using SNMP configuration Fan WWN WWN Fru Alarm Action: (0..17) [0] Alarm State: (0..31) [0] Alarm Action: (0..17) [0] configuration left unchanged Specifying triggers for alarms You can specify triggers for any number of alarm states or alarm actions. The first prompt enables you to select which FRU states trigger events. 1. Add the numbers beside each state (for the states you want to include). 2. Enter the total at the prompt.
Fabric Watch using SNMP configuration 3 In Figure 9, the MIB browser has populated the left side of the screen with a MIB tree that can be navigated. 3. Start a telnet session with the switch, and enter the snmpConfig command at the prompt; this enables you to send Fabric Watch traps to an SNMP management station.

Fabric Watch using SNMP configuration 3 Fabric Watch displays a screen similar to the one shown in Figure 10. FIGURE 10 Example OID tree 8. Obtain the specific identifier for the element that will be modified. To get the identifier, click the swFwThresholdTable and swFwThresholdEntry directory, and run a get operation on swFwName. A list of elements appears in which each element is preceded by an identifier. Remember the numeric portion of the identifier, which appears before the “==>” symbol.
3 Fabric Watch using SNMP configuration For detailed descriptions of the SNMP fields in both telnet and Web Tools, see the Fabric OS MIB Reference. FIGURE 11 Example swFwName screen In this example, 83.1 is the numeric identifier for the element referenced as resFlash000. 9. Traverse the fields beneath swFwClassAreaTable and swFwThresholdTable, appending the numeric identifier from the previous step to each field before performing a get or write operation.
