  • Page 11: Introducing Fabric Watch

    INTRODUCING FABRIC WATCH Fabric Watch allows the SAN manager to monitor key fabric and switch elements, making it easy to quickly identify and escalate potential problems. The SAN manager monitors each element for out-of-boundary values or counters, and provides notification when any exceed the defined boundaries.

  • Page 12: Threshold Behavior Models

    information specific to each monitored element is made available by Fabric Watch for viewing and, in some cases, modification. This set of information about each element is called a threshold, and the upper and lower limits of the defined ranges are called boundaries. If conditions break out of acceptable ranges, an event is considered to have occurred, and one or more alarms (reporting mechanisms) are generated if configured for the relevant threshold.

  • Page 13: Rising/Falling Threshold

    Temperature as an example of a range threshold is illustrated in Figure Temp (Celsius) Time Interval Count: Started Above In-between Below In-between -- Events (t): High Threshold Boundary: 80 Low Threshold Boundary: Unit String: “C” Time Base: None Buffer Size: 10 Figure 1.

  • Page 14: Change Monitor Threshold

    An error counter as a rising/falling threshold is illustrated in Figure Errors Time (Seconds) Rate-based 0 Count: Count: Started Below Above Below Events (t): High Threshold Boundary: 8 Low Threshold Boundary: Unit String: “Error(s)” Time Base: Second Buffer Size: 0 Figure 2.

  • Page 15: Using Fabric Watch

    USING FABRIC WATCH Fabric Watch provides the following information about each out-of-boundary condition discovered: • Name of threshold • Current value of element counter • Unit of measurement (for example, degrees Celsius, RPM, or unit of time) • Time base for counter, used to compute rate of change (for example, events per minute) •...

  • Page 16: Web Tools

    Web Tools Through Web Tools, you can: • View fabric and switch events through the fabric-wide Event View. • View and modify threshold and alarm configurations through the Fabric Watch View. • Upload and download the configuration file through the Config Admin tab in the Switch Admin window.

  • Page 17: Profiles

    The configuration file can be uploaded and downloaded through either Web Tools (the Config Admin tab in the Switch Admin window), or the Telnet commands . After configUpload configDownload downloading the file back to the switch, you must either reboot the switch or use the Telnet command to reload the configuration fwConfigReload...

    Threshold Naming Conventions All threshold names consist of the following three items, with no separators: • Abbreviation for the class name (alpha characters, lower case), as follows: Class Abbreviation Fabric fabric Environmental Port port E_Port eport F/FL_Port (Optical) fopport GBIC gbic •...

  • Page 22: Events

    Events An event is generated each time a boundary, as defined by the threshold, is crossed. Boundaries are not inclusive, so events are generated only when a boundary is exceeded, not when the monitored value has only reached them. If the event has an assigned alarm, an alarm is also generated. The alarm can be designated as an SNMP trap, an entry in the switch error log, locking of the port log, or a combination of these options.

  • Page 23: Continuous Events

    • Exceeded Counter is below the lower boundary or above the upper boundary. Accompanies a below or above event. • Changed Counter value has changed. • In-between Counter falls below the upper boundary minus buffer, or rises above the lower boundary plus buffer. Must be preceded by an above or below event.

  • Page 24: Alarms

    Alarms Each event can generate one or more alarms. Fabric Watch supports three types of alarms: SNMP trap, error log entry, and locking of the port log. SNMP Trap The following information is forwarded to an SNMP management station: • Name of the element •...

  • Page 25: Threshold Values

    Threshold Values Threshold values apply to the specific threshold. Their values are not stored in the configuration file, and return to the default values if the switch is rebooted. The following threshold values can be modified: • Status Can be enabled or disabled. Enabled by default. •...
  • Page 26 • High boundary Maximum value. An event is generated if the element value rises above this boundary. • Buffer size Size of buffer set up to decrease generation of in-between events due to oscillation of the element value over a boundary. Alarms The following alarms can be added or deleted: •...

  • Page 27: Telnet Commands

    TELNET COMMANDS The Telnet commands are available through the shell admin account. To use a Telnet command, log into the relevant switch with administrative privileges, enter the command along with any required operands, and press Enter. Fabric Watch can be accessed simultaneously from different Note connections, by Telnet, SNMP, Web Tools, or by modifying and uploading the Fabric Watch configuration file to the switch.

A TCP/IP protocol that generally uses the User Datagram Protocol (UDP) to exchange messages between a management information base and a management client residing on a network. Because SNMP does not rely on the underlying communication protocols, it can be made available over other protocols, such as UDP/IP.
