  • Page 22: Fabric Watch Overview

    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.

  • Page 23: Fabric Watch Threshold Components

    Fabric Watch threshold components 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.

  • Page 24: Security Monitoring

    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.
  • Page 25 Switch monitoring components 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. •...

  • Page 26: System Resource Monitoring

    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.

  • Page 27: Threshold Monitoring Using Snmp Tables

    Threshold monitoring using SNMP tables 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.

  • Page 28: Types Of Event Behaviors

    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.

  • Page 29: Fabric Watch Notification Types

    Fabric Watch notification types 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.

  • Page 30: Raslog (Switch Event)

    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.

  • Page 31: Data Values

    Data values 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.

  • Page 32: Monitoring

    • Step 3: Monitor FRU class areas using the fwFruCfg command. Refer to Chapter 8, “System Monitoring,” for details. NOTE For each class area, there are setting guidelines and recommendations for whether you should leave the setting at the default or change the settings. If a change is recommended, the reason for the change and the suggested settings are provided in each of the configuration chapters.

  • Page 33: Alert Configuration

    Reasons to customize Fabric Watch settings 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.

  • Page 36: Figure 1 Threshold Monitoring

    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.

  • Page 37: Time Bases

    Time bases 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.

  • Page 38: Figure 4 Event Trigger

    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.

  • Page 39: Threshold Triggers

    Threshold triggers FIGURE 5 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.

  • Page 40: Below Event Trigger

    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.
