  • Page 24: 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 25: Reasons To Customize Fabric Watch Settings

    Reasons to customize Fabric Watch settings Universal temporary license support The Fabric Watch license is available as a Universal Temporary or a regular temporary license, meaning the same license key can be installed on any switch running Fabric OS version 6.3 or later. Universal temporary license keys can only be installed once on a switch, but can be applied to as many switches as required.

  • Page 26: Monitoring

    Reasons to customize Fabric Watch settings Time base configuration The time base specifies the time interval between two samples to be compared. The fwSetToCustom command allows you to switch from default to custom settings. Valid intervals are day, hour, or minute. See “Setting Fabric Watch custom and default values”...

  • Page 27: Class, Area, And Element Hierarchy

    Class, area, and element hierarchy Class, area, and element hierarchy 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 28: 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 29: Port Persistence

    Switch monitoring components For complete information about port monitoring, including configuration examples, port setting guidelines, and default settings, refer to “Port Monitoring” on page 55. 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).

  • Page 30: System Resource Monitoring

    Logical switch support System resource monitoring System resource monitoring enables you to monitor your system’s RAM, flash, 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 31: 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 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 32: 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 one or multiple specified e-mail address.

  • Page 33: 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 34: Data Values

    Data values NOTE Audit messages are generated for port fencing configuration changes, whether port fencing is enabled or disabled. You can set up an external host to receive Audit messages so you can easily monitor unexpected changes. For information on error messages generated by Fabric Watch, see the Fabric OS Message Reference.

  • Page 37: Audit And Raslog Messages

    Threshold triggers Above event trigger Set 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.

  • Page 38: Figure 3 Event Trigger

    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). This configurable field affects the comparison of sensor-based data with user-defined threshold values.

The default CPU limit is 75 percent. When configuring memory, the limit specifies a usage limit as a percentage of available resources. When used to configure memory monitoring the limit value must be greater than the low limit and smaller than the high limit.
