31Fabric OS 5.0.0 Fabric Watch user guide
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, page 31
• Data values, page 32
• Threshold values, page 32
• Time bases, page 33
• Event settings, page 36
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, page 31
• Triggered event behavior, page 31
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.
Triggered event behavior
If you do not want notification during each sample period from the port hardware failure to
the time of its repair, you can define the event behavior as
triggered .
When an event behavior is defined as triggered, Fabric Watch sends only one event
notification when the fabric meets the criteria for the event. It does not send out any more
notifications.
