Fabric OS 5.x Fabric Watch administrator guide 19
Elements
Fabric Watch defines an element as any fabric or switch component that the software monitors. Within
each area, there are a number of elements equivalent to the number of components being monitored. For
instance, in the Core Switch 2/64, each area of the Port class will include 64 elements.
Each element contains information pertaining to the description suggested by the area. To continue the
Ports example, each element in the Invalid word area of Ports would contain exactly 64 ports, each of
which would contain the number of times invalid words had been received by the port over the last time
interval. Each of these elements maps to an index number, so that all elements can be identified in terms of
class, area, and index number. As an example, the monitoring of the temperature sensor with an index of
one may be viewed by accessing the first temperature sensor within the temperature area of the
environment class.
Subclasses are a minor exception to the above rule. Subclasses, such as E_Ports, contain areas with
elements equivalent to the number of valid entries. Within the same example used thus far in this section, in
a 64-port switch in which eight ports are connected to another switch, each area within the E_Port class
would contain eight elements.
Each area of a subclass with defined thresholds will act in addition to the settings applied to the element
through the parent class. Assignment of elements to subclasses does not need to be performed by a
network administrator. These assignments are seamlessly made through automated detection algorithms.
Configuring events
The following area attributes are used to define and detect events in Fabric Watch:
• ”Event behavior types” on page 19
• ”Data values” on page 20
• ”Threshold values” on page 20
• ”Time bases” on page 21
• ”Event settings” on page 23
You can customize the information reported by Fabric Watch by configuring event behavior types,
threshold values, time bases, and event settings. You cannot change data values; these represent switch
behavior that is updated by the software.
Event behavior types
Based on the number of notifications delivered for events there are two categories of event behavior types:
• ”Continuous event behavior” on page 19
• ”Triggered event behavior” on page 20
Continuous event behavior
Areas with event behavior types set to continuous trigger events in every sample period until the fabric no
longer meets the criteria defined for the event.
For example, you can configure Fabric Watch to notify you during every sample period that a port is at full
utilization. This information can help you plan network upgrades.
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. Current area events indicate hardware failures.
Supply Voltage The supply voltage area measures the amount of voltage supplied to the
SFP. If this value exceeds the threshold, the SFP is deteriorating.
