Monitor Policy Rule Usage
How to view rule usage for policy rules pushed to a device
group from Panorama.
As your policies change, tracking rule usage
on Panorama helps you evaluate whether your policy implementation
continues to match your enforcement needs. This visibility helps
you identify and remove unused rules to reduce security risks and
keep your policy rule base organized. Additionally, rule usage tracking
allows you to quickly validate new rule additions and rule changes
and to monitor rule usage for operations and troubleshooting tasks.
On Panorama, you can view the rule usage of firewalls in a device
group—to which you pushed policies—to determine if all, some, or
none of the firewalls have traffic matches instead of being able
to monitor only the total number of hits across all firewalls in
a device group. You can quickly filter rules using the rule usage
data, such as Created and Modified dates, within a customizable
time frame. The displayed rule usage information persists across
reboot, dataplane restarts, and upgrades.
On Panorama, you
can view the rule usage details for managed firewalls that are running
a PAN-OS 8.1 or later release, that have policy rule hit count enabled
(default), and for which you have defined and pushed policy rules
using device groups. Panorama cannot retrieve rule usage details for
policy rules configured locally on the firewall so you must log
in to the firewall to view rule usage information for locally configured
rules.
Policy rule usage data may also be useful when
using Policy Optimizer to prioritize
which rules to migrate or clean up first.
Policy rule usage data is not preserved when you transition to a different Panorama model.
This means that all existing policy rule usage data from the old Panorama is no
longer displayed after a successful migration to a new Panorama model. After a
successful migration, Panorama begins tracking policy rule usage data based on
the date the migration was completed. For example, the
Created date displays the date the migration
was completed.
To view the
rule usage across any Shared rule or for a specific device group:
- Log in to the Panorama Web Interface.
- Verify that the Policy Rule Hit Count is
enabled.
- Navigate to Policy Rulebase Settings (PanoramaSetup Management.
- Verify that Policy Rule Hit Count is enabled.
- Select Policies<policy rule> to view a rule.
- Change the Device Group context to Shared or to the specific device group you want to view.
- Determine whether the rule is being used (Rule Usage).
The policy rule usage status is one of the following:Firewalls must run PAN-OS 8.1 or later release with Policy Rule Hit Count enabled for Panorama to determine rule usage.
- Used—When all firewalls in the device group—to which you pushed the policy rule—have traffic matches for the policy rule.
- Partially Used—When some of the firewalls in the device group—to which you pushed the policy rule—have traffic matches for the policy rule.
- Unused—When no firewalls in the device group—to which you pushed the policy rule—have traffic matches for the policy rule.
- Em-dash (—)—When no firewalls in the device group—to which you pushed the policy rule—have Policy Rule Hit Count enabled or available for Panorama to determine the rule usage.
- Modified—The date and time the policy rule was last modified.
- Created—The date and time the policy rule was created.If the rule was created when Panorama was running PAN-OS 8.1 and the Policy Rule Hit Count setting is enabled, the First Hit date and time is used as the Created date and time on upgrade to PAN-OS 9.1. If the rule was created in PAN-OS 8.1 when the Policy Rule Hit Count setting was disabled or if the rule was created when Panorama was running PAN-OS 8.0 or an earlier release, the Created date for the rule will be the date and time you successfully upgraded Panorama to PAN-OS 9.1
- Click the Rule Usage status to view the list of firewalls using the rule and the hit-count data for traffic that matches that rule on each firewall.
- (Optional) View the policy rule hit-count data
for individual appliances in the device group.
- Click Preview Rules.
- From the Device context, select the appliance for which you want to view the policy rule usage data.
- Select Policies and, in the Policy Optimizer dialog, view the Rule Usage filter.
- Filter rules in the selected rulebase.You can filter the rule usage for rules pushed to firewalls from Panorama. Panorama cannot filter rule usage for rules configured locally on the firewall.Use the rule usage filter to evaluate the rule usage within a specified period of time. For example, filter the selected rulebase for Unused rules within the last 30 days. You can also evaluate rule usage with other rule attributes, such as the Created and Modified dates, which enables you to filter for the correct set of rules to review. You can use this data to help manage your rule lifecycle and to determine if a rule needs to be removed to reduce your network attack surface.
- Select the Timeframe you want to filter on, or specify a Custom time frame.
- Select the rule Usage on which you want to filter.
- (Optional) If you have reset the rule usage data for any rules, check for Exclude rules reset during the last <number of days> days and decide when to exclude a rule based on the number of days you specify since the rule was reset. Only rules that were reset before your specified number of days are included in the filtered results.
- (Optional) Specify search filters based on
additional rule data, other than the rule usage.
- Hover your mouse over the column header, and from the drop-down select Columns.
- Add any additional columns you want to filter with or to display.
- Hover your mouse over the column data that you would like to filter, and select Filter from the drop-down. For data that contain dates, select whether to filter using This date, This date or earlier, or This date or later.
- Click Apply Filter (
