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.
Exceeded Counter is below the lower boundary or above the upper boundary. Accompanies
a below or above event.
Changed Counter value has changed.
In-between Counter falls below the upper boundary minus buffer, or rises above the lower
boundary plus buffer. Must be preceded by an above or below event. If the buffer
is set to zero, this event is suppressed.
Continuous Events
A continuous event results in an event at each time interval from when the boundary is initially
exceeded until the threshold value has returned within the boundaries. For example, if port
utilization is above the upper boundary, a new event is generated at each behavior interval until
utilization falls below the upper boundary. The following events can be generated as continuous
events:
Started No alarm is generated.
Below Counter is below the lower boundary.
Above Counter is above the upper boundary.
Exceeded Counter is below the lower boundary or above the upper boundary.
Accompanies a below or above event.
Changed Counter value has changed.
Alarms
Each event can generate one or more alarms. Fabric Watch supports the following types of alarms:
• SNMP trap
• Switch event log entry
• Locking of the port log
• Email
SNMP Trap
The following information is forwarded to an SNMP management station:
• Name of the element
• Class, area, and index of the threshold
• Type of event generated
