  • 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: 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 24: Time Base Configuration

    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 25: 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 26: 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 27: System Resource Monitoring

    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 28: Switch Policies

    Logical switch support Switch policies Switch policies are a series of rules that define specific health 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. For example, you can specify a switch policy so that if a switch has two port failures, it is considered to be in a marginal state;...

  • Page 29: Mib Capability Configuration Parameters

    Fabric Watch event settings MIB capability configuration parameters The mibCapability option turns certain MIBs and associated SNMP traps on or off. If a specific MIB is disabled, the corresponding traps are also disabled. If any trap group is disabled, the corresponding individual traps are also disabled.

  • Page 30: Snmp Traps

    Fabric Watch notification types Enabling e-mail alerts for the Changed threshold state in several areas can quickly result in a significant amount of e-mail. Fabric Watch discards e-mail alerts when more than 100 are generated within a minute, which minimizes memory use. SNMP traps In environments where you have a high number of messages coming from a variety of switches, you might want to receive them in a single location and view them using a graphical user interface...

  • Page 31: Locked Port Log

    Fabric Watch audit messages Locked port log Following an event, the port log locks to retain detailed information about an event, preventing the information from being overwritten as the log becomes full. This notification audit stores event information but does not actively send alerts, which is done automatically when some thresholds are exceeded and an alert is triggered.

  • Page 32: Fabric Watch Support In Access Gateway Mode

  • Page 35: Above Event Trigger

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