Threshold values

High and low threshold values are the values at which potential problems might occur. For
example, in configuring a temperature threshold, you can select the temperatures at which a
potential problem can occur because of overheating or freezing.
With Fabric Watch v6.4 and later, the concept of high and low thresholds have been expanded to
include four threshold categories, listed below. There are two setting types (the threshold and the
above and below trigger) for four configuration possibilities. A combination of these settings can
cause the following actions to occur:
•
•
•
•
NOTE
The above low threshold action applies only to the portThConfig command. It does not apply to the
thConfig and sysMonitor commands.

Above high threshold—Fabric Watch takes this action when the current value is above the high
threshold.
Below high threshold—Fabric Watch takes this action when the current value is between the
high and low threshold. This replaces the previous "in-between" action, which no longer exists.
Above low threshold—This action is only applicable to port classes (physical port, FOP_Port,
FCU_Port, and VE_Port). Fabric Watch takes this action when the current value crosses the low
threshold towards the high threshold.
Below low threshold—Fabric Watch takes this action when the current value is below the low
threshold.
