Range Threshold

information specific to each monitored element is made available by
Fabric Watch for viewing and, in some cases, modification. This set of
information about each element is called a threshold, and the upper and
lower limits of the defined ranges are called boundaries.
If conditions break out of acceptable ranges, an event is considered to have
occurred, and one or more alarms (reporting mechanisms) are generated if
configured for the relevant threshold. There are three types of alarms:
• SNMP trap
• Entry in the switch event log
• Locking of the port log to preserve the relevant information
There are three behavior models for thresholds: range, rising/falling, and
change monitor.
A range threshold tracks whether a fabric element is within a specified
range. This threshold includes a minimum and maximum boundary for the
area, with buffer zones to prevent repeated events due to oscillation of the
value over a threshold boundary. If the value exceeds the low or high
threshold boundary, an event is generated. A range threshold can also
generate events while the value is outside the limits or when it re-enters the
prescribed range.
