Fabric Watch Thresholds

In this chapter

Threshold values

Threshold values are of the following types:
•
•

High and low thresholds

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.
You can compare high and low thresholds with a data value. The units of measurement are the
same as that of the associated data.

Buffer values

Figure 1
arrows indicate the points at which the event criteria is met. In this case, there is a great deal of
fluctuation. Even when the monitor is set to triggered, a number of messages are sent.
You can use buffer values to reduce the occurrence of events resulting from data fluctuation. When
you assign a buffer value, it is used to create a zone below the high threshold and above the low
threshold. When values cross above the high threshold or below the low threshold, an event occurs.
