Cisco Cisco Web Security Appliance S690 User Guide

When the Web Security appliance is managed by a Security Management 
appliance, you can choose which appliance displays reports on the web traffic that 
is processed by the Web Security appliance. By default, the Web Security 
appliance maintains the reports (Local Reporting). However, you can configure 
the Web Security appliance so that the Security Management appliance maintains 
the reports by enabling Centralized Reporting. You might want to enable 
Centralized Reporting when the Security Management appliance manages 
multiple Web Security appliances. This gives you a centralized view of web traffic 
across all Web Security appliances.

When you enable Centralized Reporting, only the System Capacity and System 
Status reports are available on the Web Security appliance. To view the other 
reports, connect to the Security Management appliance. The Web Security 
appliance no longer stores data for the other reports. 

To enable Centralized Reporting:

Navigate to the Security Services > Reporting page, and click Edit Settings.

Choose Centralized Reporting.

Submit and commit your changes.
