Chapter Introducing Fabric Watch 1 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. It monitors each element for out-of-boundary values or counters and provides notification when any exceed the defined boundaries.
1 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. If the value exceeds the low or high threshold boundary, an event is generated.
Introducing Fabric Watch 1 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. Events can be selected for transitions between the boundaries. Rising/falling thresholds are typically used for rate based counters.
1 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. This type of threshold is usually used to indicate state changes, such as zoning changes.
Chapter Using Fabric Watch 2 This chapter provides the following information: • Overview on page 2-1 • User Interfaces on page 2-1 • Profiles on page 2-2 • Classes on page 2-3 • Threshold Naming Conventions on page 2-7 • Events on page 2-7 • Alarms on page 2-8 • Configuring Thresholds and Alarms on page 2-9 Overview 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, de
2 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. • Upload and download the configuration file through the commands configUpload and configDownload.
Using Fabric Watch 2 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.
2 Using Fabric Watch 3 - Monitors CRC errors of prefedined SID-DID pair. Configurable with either telnet commands or Web Tools at run time. The configuration information of the End-to-End class is lost when the switch is rebooted or fast booted. Note: The End-to-End class is only available if the optional Performance Monitoring license has been purchased and turned on. Note: The EE filter is preconfigured with either a telnet command or Web Tools at run time.
Using Fabric Watch Class Area Description Environmental Temperature Monitors switch temperature. Fan Monitors operation of switch fans. Power supply Monitors status of each power supply. Link failure count Monitors link failure count for each port. Loss of synchronization count Monitors port sync loss. Loss of signal count Monitors port signal loss. Primitive sequence protocol error Monitors port protocol errors. Invalid transmission word Monitors port invalid words.
2 Using Fabric Watch Class Area Description Invalid CRC count Monitors optical F/FL_port CRC errors. Receive performance Monitors optical F/FL_port receive performance. Transmit performance Monitors optical F/FL_port transmit performance. State changes Monitors optical F/FL_port state changes. Temperature Monitors SFP temperature. Receiver power Monitors SFP receiver power. Transmitter power Monitors GBIC transmitter power. Current Monitors GBIC current.
Using Fabric Watch 2 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 Fabric Environment Port E_Port F/FL_Port (Optical) GBIC ALPA End-to-End Filter Abbreviation fabric env port eport fopport gbic alpa ee flt • Abbreviation for the area name (alpha characters, title case). For example, “Temp” for the Temperature area.
2 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. Exceeded Counter is below the lower boundary or above the upper boundary. Accompanies a below or above event. Changed Counter value has changed.
Using Fabric Watch • 2 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. It is typically used in conjunction with the error log entry. Email Alert The Email Alert sends alarms to the corresponding email addresses at run time.
2 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. Time base Time period within which a specified event is measured. Can be from one second to one day.
Appendix Example Error Message A This appendix provides an example Errlog message. Overview Figure A-1 shows a typical Fabric Watch Errlog message. Severity of Error Message 3 = Warning 4= Informational Threshold Names Threshold Labels Index Numbers 0x1003f2d0 (tThad): May 22 19:20:23 Error FW BELOW, - 3, fopportState003 FOP Port( State Changes 3 ) is below low boundary . current value : 0 Change(s)/minute. ( normal) 0x1003f2d0 (tThad): May 22 19:13:57 ( Invalid CRCs 7 ) is above high boundary.
