> #### Reviewing the recommended threshold settings

> The recommendations that the Configuration Advisor presents include a range of possible values from which to select. The asterisked value that appears in the Recommend Values field indicates the primary recommended threshold setting, based on the data analysis. Click on the drop-down list to see the additional recommended values, as shown in Figure 4–4.

> Figure 4–4: Recommended threshold values for disk resource

> If there were more than one rule being evaluated by the Configuration Advisor for this resource, each rule would appear in its own row, with its own recommended values, update, current threshold, and Detail button.

> Each recommended value is expressed as a pair of numbers. The first number specifies the recommended threshold setting; the second number, displayed in brackets, identifies the number of times this threshold value, if used with the collected data, would have broken the rule and triggered an alert. As you review the recommended threshold settings, keep in mind the rule behavior and alert notification frequency you want to establish for a resource.

> ##### Reviewing threshold calculation details

> Each row has an associated Detail button that displays information about the rule's analysis, as shown in Figure 4–5.
