The Policy Analysis Tool evaluates the rules within a policy. It looks for high processing cost and unpredictable results.
This tool is currently available for the Edge Redirector Cloudlet only.
By default, the tool uses the property hostname associated with the Cloudlets policy. You can also analyze rules against a different hostname and an Akamai server IP address.
Once complete, you can:
- View the results on the screen.
- Show or hide specific rules.
- View only errors.
- Download the report in CSV format.
- Enter different settings and click Rerun Analysis to generate a new report.
Rules excluded from Policy Analysis UI & Reports
Rules that have a Redirect Url longer than 256 characters are not listed in the Policy Analysis tool and they are not included in downloaded reports.
Rules that have a cURL Command longer than 512 characters are not listed in the Policy Analysis tool and they are not included in downloaded reports.
The exclusions are due to a Policy Analysis tool limitation and doesn't mean that there is an issue with the command or that the redirect is not working.
Before using the Policy Analysis Tool, make sure these things are activated on the staging network:
- an Edge Redirector policy.
- a property that refers to the policy version to be tested. The property needs to have an Edge Redirector behavior.
If a policy meets these requirements, the Policy Analysis tab is enabled next to the Rule List tab.
Policy Analysis Tool is not yet available for Shared Policy.
Open an Edge Redirector policy version that meets the analysis requirements.
On the Version Details screen, click the Policy Analysis tab.
If you want to specify a different hostname and Akamai server IP address to test:
Click the checkbox.
Enter the desired hostname or IP address.
Click Analyze Policy Version.
Review the data in the report fields.
If you want to download the report, click Download Report.
If you want to generate a new report, enter new settings and click Rerun Analysis.
The following are the fields on the Policy Analysis tab:

- Redirect URL. The URL used to test the given rule.
- Status. The HTTP status code returned.
- Executed. Whether the test request triggered the rule.
- Cost. The system cost of executing the rule.
Once the results display on the Policy Analysis tab, you can download the report in CSV format.
Click Download Report to generate the CSV file.
