  • Page 9: Introducing Fabric Watch

    Chapter Introducing Fabric Watch This chapter provides the following information: • Overview on page 1-1 • Threshold Behavior Models on page 1-2 Overview Fabric Watch is used by SAN managers to monitor key fabric and switch elements, making it easy to quickly identify and escalate potential problems.

  • Page 10: Threshold Behavior Models

    Introducing Fabric Watch Threshold Behavior Models The behavior models for thresholds are: • Range • Rising/falling • Change monitor Range Threshold A range threshold tracks whether a fabric element is within a specified range. It includes a minimum and maximum boundary for the area, with buffer zones to prevent repeated events due to oscillation of the value over a threshold boundary.

  • Page 11: Rising/Falling Threshold

    Introducing Fabric Watch Figure 1-1 shows a typical example of an error counter with a temperature range threshold. Figure 1-1 Example of Range Threshold: Temperature (Celsius) Rising/Falling Threshold A rising/falling threshold tracks whether an element is on the desired side of a boundary. It includes an upper and lower boundary, and the buffer zones are always zero.

  • Page 12: Change Monitor Threshold

    Introducing Fabric Watch Figure 1-2 shows a typical example of an error counter with a rising/falling threshold. Figure 1-2 Example of Rising/Falling Threshold: Error Rate Change Monitor Threshold A change monitor threshold generates events whenever a counter value changes, regardless of the type of change.

    Using Fabric Watch Telnet Interface You can do the following using a telnet interface: • Query fabric and switch events through the telnet command fwShow. • Query and modify threshold and alarm configurations. Use the telnet command fwConfigure to view the default and customized settings. •...

  • Page 15: Classes

    Using Fabric Watch A profile may contain the following information: • Threshold values: Unit string Time base Lower boundary Upper boundary Buffer size • Alarm values Change Exceed Below Above In-between Behavior type Classes Fabric and switch elements are organized into classes (also known as Agents), which are groupings of closely related elements.

  • Page 20: Continuous Events

    Using Fabric Watch The following events can be generated as triggered events: Started No alarm is generated. Below Counter is below the lower boundary. Must be preceded by a start, above, or in-between event. Above Counter is above the upper boundary. Must be preceded by a start, below, or in-between event.

  • Page 21: Error Log Entry

    Using Fabric Watch • New state of element Error Log Entry The internal error log maintains a record of the event, up to a maximum of 64 entries. If configured to do so, error log entries are forwarded to the SYSLOGD facility. Locking the Port Log Locking the Port Log freezes the switch port log to retain detail information about a problem.

  • Page 22: Threshold Area Values

    Using Fabric Watch Threshold Area Values Threshold area values include boundaries and alarms, and apply to all the thresholds within an area. Changes are stored in the configuration file. Boundaries The following boundary information can be modified: Unit string Represents unit value. Only the default unit strings are supported by Fabric Watch.
