- Click OK to begin the ad hoc analysis.
- View policy analyzer results by clicking the View results link and
selecting either Ad hoc analysis or Continuous
For continuous analysis, use the Time frame setting to change how much data is displayed. For ad hoc analysis, use the Start time menu to view a specific set of ad hoc results.
The % fired among transactions for each rule chart shows what percentage of all transactions cause each rule to fire. Because not all transactions fire a rule, the total will not always equal 100%.
The Top rules (fire count) chart shows the number of times that a rule fired during the continuous analysis period or during the ad hoc analysis. Click the chart to see a key that identifies the chart contents. Click the Top rules (fire count) label and select Change selected rules to hide or show specific rules in the chart.The Details for all policy rules table summarizes activity for policies, rules, and rule actions.

- Use the % fired among rules column to see which rules are firing the most, expressed as a percentage of all rules that have fired during the specified time frame.
- Investigate specific results.
- Click a bar in the % fired among transactions chart to select the corresponding row in the Details for all policy rules table or click to select any row in the table.
