DRAFT: BROCADE CONFIDENTIAL
At the tenth sample, the rate of change is one per minute. At the fourteenth, twenty-first, and
twenty-fifth sample, the rate of change remains equal to the high threshold of 2. In this case, Fabric
Watch does not trigger an event even though the absolute value of the counter reaches 4, which is
well above the high threshold.

Event settings
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,” next
• “Below event trigger” on page 17
• “Changed event trigger” on page 18
• “In-between event triggers” on page 18
For Fabric Watch to monitor these conditions, the alarm setting must be set to a nonzero value.
