This section describes how Fabric Watch compares a fabric element’s data value against a
threshold value to determine whether or not to trigger an event. It describes how a specified
buffer zone impacts event triggering.
Fabric Watch monitors data values for one of the following conditions:
• Above event triggers, page 37
• Below event trigger, page 37
• Changed event trigger, page 37
• In-Between triggers, page 38
For Fabric Watch to monitor these conditions, the alarm setting must be set to a non-zero
value.
