Fabric Watch Best Practices

Fabric Watch default settings

A default Fabric Watch configuration is available for the purpose of saving setup time. As you
become more familiar with Advanced Fabric Watch features, you can tailor them to suit the fabric
environment. The custom settings available in Fabric Watch provide an advanced user flexibility for
redefining boundary thresholds and alarm notification methods. The basic concept of Fabric Watch
is to monitor the health of an element by sampling the status, comparing the sample data, and if
found outside the threshold limits, to notify the user of the event using one or more selected
methods.
Because Fabric Watch monitors a variety of classes and class elements, each element with a
unique trait must be evaluated prior to defining custom thresholds to meet a specific objective.
This section discusses some of the changes that you should consider implementing to improve the
overall efficiency of Fabric Watch.
