Types of event behaviors

Based on the number of notifications delivered for events, there are two categories of automatic
notifications:
•
•
Continuous event behavior
A continuous alarm provides a warning message whenever a threshold is breached; it continues to
send alerts until the condition is corrected. For example, if a switch exceeds its temperature
threshold, Fabric Watch activates an alarm at every measurement interval until the temperature
returns to an acceptable level.
You can set behavior type events to continuously trigger during a given sample period, until the
fabric no longer meets the criteria defined for the event.
As an 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
A triggered alarm generates the first warning when a threshold condition is reached and a second
alarm when the threshold condition is cleared.
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. Triggered is the default behavior type
signal for all class areas.
For example, when a port fails, Fabric Watch sends you a notification of the failure. After you repair
the port, Fabric Watch detects the repair. At this time, Fabric Watch determines that the fabric no
longer meets the event criteria, and watches for the error again. The next time the port fails, it
sends you another notification.
Whereas a triggered behavior type sends only one event notification when the fabric meets the
criteria for the event, a continuous behavior type signals you continuously after a threshold has
been crossed.
