Evaluating recommended settings

As Figure 7–3 shows, each rule the Configuration Advisor has analyzed appears as an individual line item in the Rule section. Associated with each rule is a Recommended Values drop-down list which contains one of the following entries:

Reviewing recommended values

The Configuration Advisor displays a range of possible values from which to select. Figure 7–4 shows the full range of seven recommended values for the Process CPU High rule. Note that the Configuration Advisor's primary (default) recommendation displays in the Recommended Values field with an asterisk.

Figure 7–4: Recommended Values field content

Each recommended value is expressed as a set of two numbers. The first number (in each row) specifies the recommended threshold setting. The second number, displayed in brackets, identifies the number of times the threshold value set at the associated setting would be exceeded and an alert fired. The asterisked number indicates the Configuration Advisor's primary recommendation. As you review the recommended threshold settings, note the rule behavior and alert notification frequency you want to establish for a resource.

Using the Detail button

Each rule row has an associated Detail button.

To display details about a rule's analysis, click Detail for a row. The Detail page appears.

Figure 7–5 shows an example of a Detail page, displaying the data used to evaluate the Queued Request Percent High rule.

Table 7–3 describes the contents of the Detail page.

Table 7–3: Detail page fields and descriptions 
This field . . .
Describes . . .
Number of useable samples
The number of data samples extracted from the OpenEdge Management Trend Database.
Min Value
The minimum value derived from the data set.
Max Value
The maximum value derived from the data set.
Std Deviation
The root mean squared deviation.
Average
The average value derived from the data set.

Note: The Detail page for a rule for which there is insufficient data for analysis identifies the number of samples found. This number is always lower than the minimum of 32 data samples required. Review this data to help you decide if you need to expand the time period to try to capture more samples and rerun the Configuration Advisor for a given rule.
