1 Introduction to fabric health Fabric Watch lets you define how often to measure each switch and fabric element and to specify notification thresholds. Whenever fabric elements exceed these thresholds, Fabric Watch automatically provides notification using several methods, including e-mail messages, SNMP traps, and log entries.
Fabric Watch components 1 Although the concept of fabric health initially seems fairly simple, it can be a deep and complex topic due to the number of factors that are involved. One of the more obvious criteria for fabric health is the condition of the network hardware. A switch or port failure could easily prevent data packets from reaching their destination. Network traffic can also influence fabric health.
1 Fabric Watch components Table 1 describes the classes into which Fabric Watch groups all switch and fabric elements. TABLE 1 Product Name classes Class Description Environment Includes information about the physical environment in which the switch resides and the internal environment of the switch. For example, an Environment-class alarm alerts you to problems or potential problems with temperature, fans, and power.
Fabric Watch components 1 Environment class areas Table 2 lists and describes the Product Name areas in the Environment class. TABLE 2 Environment class areas Area Description Fan Refers to the speed of the fans inside the switch, in revolutions per minute. It is important that the fans spin quickly enough to keep the ambient temperature from rising to levels at which switch damage might occur. Power Supply Monitors whether power supplies within the switch are on, off, present, absent, or faulty.
1 Fabric Watch components TABLE 3 Fabric class areas (Continued) Area Description Loss of E_Port Tracks the number of times that an E_Port or VE_Port goes down. E_Ports and VE_Ports go down each time you remove a cable or an SFP (where there are SFP failures or transient errors). Segmentation Changes Tracks the cumulative number of segmentation changes. Segmentation changes occur due to: • Zone conflicts. • Incompatible link parameters.
Fabric Watch components 1 Performance Monitor class areas Table 5 lists Product Name 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.
1 Fabric Watch components Port class areas Table 6 lists and describes the Product Name areas in the port class. NOTE Fabric Watch monitors and reports the status of physical and virtual FC ports. Physical GbE ports and ISCSI ports are not monitored and are not included in the Port Class area. TABLE 6 Port class areas Area Indicates Invalid Cyclic Redundancy Checks (CRCs) A frame is invalid and cannot be transmitted. Invalid CRCs can represent noise on the network.
Fabric Watch components 1 Resource class area Table 7 describes the Product Name resource class area. TABLE 7 Resource class area Area Description Flash Monitor Monitors the compact flash space available by calculating the percentage of flash space consumed and comparing it with the configured high threshold value. Security class areas Table 8 lists Product Name areas in the security class and describes what each area indicates.
1 Fabric Watch components TABLE 8 Security class areas (Continued) Area Indicates SLAP Bad Packets A SLAP (Switch Link Authentication Protocol) bad packets failure occurs when the switch receives a bad SLAP packet. Bad SLAP packets include unexpected packets and packets with incorrect transmission IDs. SLAP Failures A SLAP failure occurs when packets try to pass from a nonsecure switch to a secure fabric.
Configuring events 1 Subclasses are a minor exception to the preceding mapping rule. Subclasses, such as E_Ports, contain areas with elements equivalent to the number of valid entries. Within the same example used thus far in this section, in a 64-port switch in which eight ports are connected to another switch, each area within the E_Port class would contain eight elements.
1 Configuring events 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 incremental.
Configuring events 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.
1 Configuring events Figure 3 shows a high limit of 65 degrees Celsius placed on a counter measuring temperature. During each sample period, Fabric Watch measures the temperature and compares it against the high threshold. If the measured temperature exceeds the high threshold, it triggers an event. FIGURE 3 Time base set to none Specifying a time base If you specify a time base value other than none (seconds, minute, hour, or day), Fabric Watch does not use the current data value.
Configuring events 1 As illustrated on the tenth sample, the counter value changes from 0 to 1; hence calculated rate of change is 1 per minute. At the thirteenth sample, the rate of change is 2 per minute. The rate of change must be at least 3 per minute to exceed the event-triggering requirement of 2, which is met on the eighteenth sample.
1 Configuring events 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.
Configuring events 1 the high threshold (event 1 in Figure 6). When the data value becomes less than the high threshold and buffer value, Fabric Watch triggers a second event (Event 2) to indicate that it has returned to normal operation. The second event will not be triggered until the counter value falls below the high threshold and buffer values.
1 Port persistence In-between event triggers Fabric Watch event triggers are usually set to notify the user of a warning or failure condition, but there is an exception. You can define the In-Between event trigger to receive a notification of fault recovery. For example, when measuring port performance, crossing the high threshold triggers an Above threshold event, which displays a warning message. The threshold might be crossed for a period so brief that is not a true cause for an alarm.
Notification methods 1 Fabric Watch uses port persistence for a port event that requires the transition of the port into a marginal status. Fabric Watch does not record any event until the event persists for a length of time equal to the port persistence time. If the port returns to normal boundaries before the port persistence time elapses, Fabric Watch does not record any event. The port persistence time is measured in seconds, and can be configured.
1 Notification methods • • • • • Class, area, and index number of the threshold that the counter crossed Event type Value of the counter that exceeded the threshold State of the element that triggered the alarm Source of the trap The trap stores event information but does not actively send alerts. Port changes do not generate SNMP traps. RAPI TRAP RAPI Trap is a Fabric Watch alarm that actively alerts you to events.
Switch policies 1 ASSIGNING NOTIFICATION METHODS Specify the particular notification method that you want Fabric Watch to use by assigning it a value. Table 10 shows the numerical values for each notification method.
