1 Fabric Watch overview Fabric Watch overview Fabric Watch is an optional storage area network (SAN) health monitor that allows you to enable each switch to constantly monitor its SAN fabric for potential faults and automatically alerts you to problems long before they become costly failures. Fabric Watch tracks a variety of SAN fabric elements and events. Monitoring fabric-wide events, ports, and environmental parameters enables early fault detection and isolation as well as performance measurement.
Fabric Watch threshold components 1 Fabric Watch threshold components Fabric elements and events are organized in a hierarchy by class, area, and element. 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. An example of a very simple Class --> Area --> Element hierarchy follows.
1 Switch monitoring components The Performance Monitor class is divided into the following areas: • EE (end-to-end) Performance Monitor - monitors RX and TX performance between two devices. • Filter Performance Monitor - measures the number of frames transmitted through a port that match specific values in the first 64 bytes of the frame.
Switch monitoring components 1 If frame discard errors or any other configured areas exceed the currently effective threshold settings, the Fabric Watch daemon can take one or more of the following actions: • • • • • Send an SNMP trap. Log a RASlog message. Send an E-mail alert. Log a port log message. Enable port fencing. Refer to “Port fencing” for more information.
1 Switch monitoring components System resource monitoring System resource monitoring enables you to monitor your system’s RAM, flash, memory, and CPU. You can use the sysMonitor command to perform the following tasks: • Configure thresholds for Fabric Watch event monitoring and reporting for the environment and resource classes. Environment thresholds enable temperature monitoring, and resource thresholds enable monitoring of flash memory.
Threshold monitoring using SNMP tables 1 Threshold monitoring using SNMP tables Understanding the components of SNMP makes it possible to use third-party tools to view, browse, and manipulate Brocade switch variables (MIBs) remotely. Every Brocade switch and director supports SNMP. When an event occurs and its severity level is at or below the set value, the Event Trap traps swFabricWatchTrap), are sent to configured trap recipients. In Fabric OS v6.4.
1 Fabric Watch event settings Types of event behaviors Based on the number of notifications delivered for events, there are two categories of automatic notifications: • Continuous event behavior • Triggered event behavior Continuous event behavior A continuous alarm provides a warning message whenever a threshold is breached; it continues to send alerts until the condition is corrected.
Fabric Watch notification types 1 Fabric Watch notification types Fabric Watch provides event notifications in several different formats to ensure that event details are accessible from all platforms and operating systems. In response to an event, Fabric Watch can record event data as any (or all) of the following alarm options. E-mail alert An e-mail alert sends information about a switch event to a specified e-mail address.
1 Fabric Watch audit messages You must configure the software to receive trap information from the network device. You must also configure the SNMP agent on the switch to send the trap to the management station. You can configure SNMP notifications using the snmpConfig command and you can configure notifications using Fabric Watch. For information on configuring the SNMP agent using the snmpConfig command, see the Fabric OS Command Reference.
Data values 1 Data values A data value represents a measured value or a state value: • Measured value is the current, measurable value of a fabric or fabric element, such as environmental temperature. • State value, which is the only qualitative data value, provides information on the overall state of a fabric component. Instead of numerical data, state values contain information on whether components are faulty, active, or in another state.
1 Reasons to customize Fabric Watch settings Monitoring Do you want to monitor all class areas, or implement the monitoring in incremental stages? If you monitor class areas incrementally, you should configure Fabric Watch to monitor the classes in the following order: • Step 1. Monitor Fabric class areas using the thConfig command. Refer to Chapter 6, “Fabric, Security, SFP, and Performance Monitoring,” for details. • Step 2: Monitor Port class areas using the portThConfig command.
Reasons to customize Fabric Watch settings 1 Alert configuration When Fabric Watch is improperly configured, a large number of error messages can be sent over a short period of time, making it difficult to find those messages that are actually meaningful. If this happens, there are a few simple ways to improve the configuration. When large numbers of unimportant messages are received, examining the source can identify those classes which need to be reconfigured.

2 Threshold values FIGURE 1 Threshold monitoring Figure 2 shows how to limit the number of event notifications using a buffer. When you specify a buffer, events cannot occur below the high threshold and above the low threshold. Event notification occurs only where the arrows indicate. The event criteria are continued to be met until the data sensed falls below the low threshold value or above the high threshold value.
Time bases 2 Time bases Time bases specify the time interval between two samples to be compared. You can set the time base to day (samples are compared once a day), hour (samples are compared once an hour), minute (samples are compared every minute), or second (samples are compared every second). This configurable field affects the comparison of sensor-based data with user-defined threshold values.
2 Time bases Example 1: 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. It should be either higher than the high threshold limit or lower than the low threshold limit.
Threshold triggers FIGURE 5 2 Example without an event Threshold triggers This section describes how Fabric Watch compares a fabric element’s data value against a threshold value to determine whether or not to trigger an event. It describes how a specified buffer zone affects event triggering. For Fabric Watch to monitor data values for one of the following conditions, the alarm setting must be set to a nonzero value.
2 Threshold triggers FIGURE 6 Above event trigger with buffer zone Below event trigger The Below event trigger generates an event when a data value becomes less than the low threshold boundary. When a buffer is defined, the event will be triggered only when the value goes below the lower threshold. A second event will not be generated until the value crosses the buffer region set above the lower threshold.
Threshold triggers 2 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. Notifications are generated only for the following transitions: • IN_RANGE to OUT_OF_RANGE • OUT_OF_RANGE to IN_RANGE No alarm is generated for INFORMATIVE to IN_RANGE (or IN_RANGE to INFORMATIVE).

3 Fabric Watch classes, areas, and elements • Chapter 8, “System Monitoring” The Resource class and Environment class areas and actions are configured using the sysMonitor command. The FRU class actions are configured using the fwFruCfg command Elements Fabric Watch defines an element as any fabric or switch component that the software monitors. Within each area, the number of elements is equivalent to the number of components being monitored.
Fabric Watch classes, areas, and elements TABLE 1 3 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 sub-classes: • E_Port class—Represents ports connected to another switch.

7 Port class guidelines and default settings FOP_Port and FCU_Port subclass setting guidelines FOP_Port and FCU_Port guidelines for the areas listed below represent a more aggressive approach in most areas. NOTE The settings in these subclasses include settings for the host bus adapter (HBA) ports as well as the storage ports.
Port class guidelines and default settings 7 • Area: Class 3 (C3) Discards Unlike the other areas, take a conservative approach for the C3 Discards area. Use the default settings and configure the alarms for Above. The goal is to locate issues with the device or its infrastructure, so monitor the data to help isolate issues. Port fencing is one of the recommended solutions for isolating issues.

TABLE 18 VE_Port class default settings Area Description Default threshold settings Default alarm settings Threshold state Packet Loss The number of packets routed through a port exceeds the port bandwidth.
7 Port configuration Port configuration Use the portThConfig command to configure thresholds for Fabric Watch event monitoring for all ports of a specified type and to display the configuration and current port status in real time. The command syntax is detailed in the Fabric OS Command Reference Guide. Before you configure thresholds, you must first identify and select the appropriate class and areas, which are described in “Port class areas” on page 57.
portThConfig command procedures 7 portThConfig command procedures The following sections provides specific examples for the Port class. See “Port class guidelines and default settings” on page 59 for recommendations on how to set areas for the physical port, the E_Port, the FOP_Port, and the FCU_Port . Port type: physical port In general, use the generic Port class to provide supplemental data for the specific E_Port, FOP_Port, or FCU_Port classes.
7 portThConfig command procedures 2. Apply the changes. portthconfig --apply port -area itw -action_level cust -thresh_level cust Port type: E_Port E_Port, FOP_Port, and FCU_Port guidelines represent a more aggressive approach in most areas than physical port guidelines, because failing or failed E_Ports, FOP_Ports, and FCU_Ports in a large fabric can cause serious fabric-wide issues if not detected early. The following examples represent a sample configuration for an E_Port.
portThConfig command procedures 7 Configuring an E_Port with a Class 3 Discards area Class 3 (C3) discards frames because of timeouts (on 8 Gbps platforms only). 1. Enter the portThConfig command using the following parameters: portthconfig --set e-port -area c3tx_to -highth -value 5 -trigger above -action raslog,snmp,email,portlog • Unlike other areas, take a conservative approach for the C3 Discards area. Use the default setting of 5. • Triggers specify actions for in-range port behavior.
7 portThConfig command procedures Configuring an E_Port with a Loss of Synchronization Count area Loss of synchronization occurs when two devices fail to communicate at the same speed. Synchronization errors are always accompanied by a link failure, and frequently occur due to a faulty SFP or cable. 1.
portThConfig command procedures 7 Configuring an E_Port with a Transmit Performance area The Transmit (Tx) Performance area is used to monitor the bandwidth utilization of the interswitch (ISLs) in the fabric. 1. Enter the portThConfig command using the following parameters: portthconfig --set e-port -area tx -highth -value 75 -trigger above -action raslog,snmp,email,portlog • Set the high threshold value to 75 percent (the default is 100). • Triggers specify actions for in-range port behavior.
7 Port fencing Setting the port persistence time Port persistence is used to transition a port into a marginal status. Fabric Watch does not record the 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 the event. The port persistent time is measured in seconds and can be configured. Configuring the port persistence time to zero disables this feature.
Port fencing 7 Recommended high port fencing thresholds It is recommend you use conservative thresholds to prevent false triggers. Examples for the Invalid Transmitted Words and Invalid CRCs are shown in Table 19.
7 Port fencing See “Port class guidelines and default settings” on page 59 for more information about the Port class areas and under what circumstances port fencing is recommended. 1. Connect to the switch and log in as admin. 2. Enter the portFencing command to display the list of operands. The portFencing menu displays.
Port fencing 7 Port fencing requirements To configure port fencing using the DCFM management application, all Fabric OS devices must have Fabric Watch and must be running firmware Fabric OS 6.2 or later. Port fencing threshold areas supported on DCFM You can add, edit, view, or remove thresholds on the following area types using DCFM. You can then assign the thresholds to available objects in the DCFM tree.
7 Recommended port configuration settings Recommended port configuration settings Table 21 lists the recommended settings for physical port, E_Port, FOP_Port, and FCU_Port for both the host device and the storage device.
