Use the client validation logs to view detailed information about clients when they validate with the Policy Server. Validation occurs when the ACS server retrieves client security posture data and sends it to the Policy Server, which compares the data to policies and rules (see The Client Validation Sequence).
To generate client validation logs, when adding or editing a new rule or policy, select the check box under Server-side actions.
To access the web console screens for Cisco ACS logs, go to the Policy Server web console and click Logs > View Client Validation Logs on the main menu.
