The ability to set alerts is a powerful feature that allows you to monitor your systems for abnormal events or behavior without actually seeing the event occur.
An alert can be configured for all subscripts of a single metric. This eliminates the need to create an alert for each subscript of the array. For example, a disk array may have several subscripts, and configuring individual alerts would be tedious and time-consuming, as well as error-prone. In addition, subscripts may be different on different systems. Thus, the ability to configure an array alert that can be applied to multiple systems provides many benefits.
