To view firewall reports:

  6. The following reports are segregated and displayed as widgets on the Firewall screen:
    • Unused Objects Report - A doughnut chart that categorizes the list of unused objects fetched from the device based on its hit count. Selecting the from and to date and the policy name from the respective fields will retrieve the list of unused objects from the selected policy during the specified interval.

    • Optimization report for NAT - A bar chart that shows the number of policies available for a defined NAT rule category. Select the policy from the Policy Name dropdown list for which you want to retrieve the report. When you can click on any bar, the control center view of the rule is displayed in the control grid (varies based on the policy, object, and rule parameters).
    • Top 30 Most Used Security Rules - A bar chart that shows the most common security rules along with the number of times each has been used. Users can click the dropdown list at the top of the chart to select the policy whose security rules they want to view.
