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, there are four threshold categories:
• 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.
• 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.
NOTE
The above low threshold action applies only to the portThConfig command. It does not apply to the
thConfig and sysMonitor commands.
In-between buffer values
The below high threshold is the term used to configure "in between" buffer values, as shown in the
figure below.
The following example the high threshold value is 5 and the buffer value is 1. Therefore, the "in-
between" boundary value is 4.
