Triggered Events

22
An event is generated each time a boundary, as defined by the threshold, is
crossed. Boundaries are not inclusive, so events are generated only when a
boundary is exceeded, not when the monitored value has only reached
them. If the event has an assigned alarm, an alarm is also generated. The
alarm can be designated as an SNMP trap, an entry in the switch error log,
locking of the port log, or a combination of these options.
When an item such as an E_Port, F/FL_Port (Optical), FINISAR Smart
GBIC, fan, or power supply is removed, Fabric Watch can raise an event
(such as a below event), then the threshold is hidden and disabled. When an
item is added, the threshold is displayed and enabled, and Fabric Watch can
raise an event.
Event policies control the generation of events, and can be configured for
either triggered events or continuous events.
A triggered event results in a single event when a boundary is exceeded.
The event is not generated again until the threshold value has returned
within the boundaries and then once again exceeded them. For example, if
the switch temperature exceeds the upper boundary, a triggered event is
generated at the point the boundary is crossed, but is not repeated while the
temperature remains above the upper boundary.
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.
