  • Page 12: Introduction To Fabric Health

    Following an event, Fabric Watch adds an entry to the internal port log for an individual switch and freezes the log to ensure that detail-level information is available. • RapiTrap Following an event, Fabric Watch forwards event information to a proxy switch, which then forwards the information to a server to notify you.

  • Page 14: Areas

    Table 2 Fabric Watch classes (continued) Class Description Performance Monitor Serves as a tuning tool. Performance Monitor classes group areas that track the source and destination of traffic. Use the Performance Monitor class thresholds and alarms to determine traffic load and flow and to reallocate resources appropriately.

    Fabric class areas Table 4 lists Fabric Watch areas in the Fabric class and describes each area. Table 4 Fabric class sreas Area Description Domain ID Changes Monitors forcible domain ID changes. Forcible domain ID changes occur when there is a conflict of domain IDs in a single fabric and the principal switch has to assign another domain ID to a switch.

    Table 9 Security class areas (continued) Area Indicates Invalid Signatures If a switch cannot verify the signature of a packet, the switch rejects the packet and the signature becomes invalid. Invalid Timestamps If a time interval becomes too great from the time a packet is sent to the time it is received, the timestamp of the packet becomes invalid and the switch rejects it.

    Table 10 SFP class areas (continued) Area Description Transmit Power The transmit power area measures the amount of outgoing laser, in µwatts. Use this to determine the condition of the SFP. If the counter often exceeds the threshold, the SFP is deteriorating. Current The current area measures the amount of supplied current to the SFP transceiver.

  • Page 20: Triggered Event Behavior

    Triggered event behavior If you do not want notification during each sample period from the port hardware failure to the time of its triggered repair, you can define the event behavior as When an event behavior is defined as triggered, Fabric Watch sends only one event notification when the fabric meets the criteria for the event.

  • Page 21: Time Bases

    Figure shows an example in which each time a signal crosses the high limit, an event occurs. The blue arrows indicate the area where the event criteria is met. In this case, there is a great deal of fluctuation. Even when the monitor is set to triggered, a number of messages are sent. Figure 1 Threshold monitoring Figure...

  • Page 22: Specifying A Time Base

    Specifying a time base If you specify a time base value other than none seconds minute hour , or ), Fabric Watch does not use the current data value. Instead, it calculates the difference between the current data value and the data value as it existed one time base ago.

    does not trigger an event even though the absolute value of the counter reaches 4, which is well above the high threshold. Figure 5 Example without an event Event settings This section describes how Fabric Watch compares a fabric element’s data value against a threshold value to determine whether or not to trigger an event.

  • Page 24: Below Event Trigger

    Below event trigger The Below event trigger generates an event when a data value becomes less than the low threshold boundary. When a buffer is defined, the data value must be below the buffer value and the low threshold. Changed event trigger Use the Changed event trigger for an element that requires “rate of change”...

  • Page 25: Port Persistence

    Port persistence In the case of port monitoring, there is an additional factor to consider. The data collected in port monitoring can vary a lot 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). Fabric Watch uses port persistence for a port event that requires the transition of the port into a marginal status.

  • Page 26: Rapitrap

    The trap stores event information but does not actively send alerts. Port changes do not generate SNMP traps. RAPITrap RAPITrap is a Fabric Watch alarm that actively alerts you to events. After you enable RAPITrap, Fabric Watch forwards all event information to a designated proxy switch. The host API automatically configures the proxy switch, based on firmware version.

  • Page 27: Switch Policies

    Switch policies Switch policies are a series of rules that define specific 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;...

    Locate the Fabric Watch OID information per the following screen: Configuration file Use a configuration file to: • Upload a configuration file, make changes in a text editor, and download the file to all switches. • Upload and download the configuration file through a telnet session or with Web Tools. Uploading and downloading a configuration file to multiple switches efficiently populates your SAN with consistent Fabric Watch settings.
