Cisco Cisco Web Security Appliance S690 User Guide

The Reporting > System Capacity page displays current and historical information about resource 
usage on the Web Security appliance.

When choosing time ranges for viewing data on the System Capacity page, the following is important to 
remember:

Hour Report. The Hour report queries the minute table and displays the exact number of items, such 
as bytes and connection, that have been recorded by the appliance on an minute by minute basis over 
a 60 minute period. 

Day Report. The Day report queries the hour table and displays the exact number of items, such as 
bytes and connection, that have been recorded by the appliance on an hourly basis over a 24 hour 
period. This information is gathered from the hour table. 

The Week Report and 30 Days Report work similarly to the Hour and Day Reports.

Use the Reporting > System Status page to monitor the System Status. This page displays the current 
status and configuration of the Web Security appliance.

Web Security Appliance 
Status

System uptime

System resource utilization — CPU usage, RAM usage, and 
percentage of disk space used for reporting and logging.

RAM usage for a system that is working efficiently may be above 90%, 
because RAM that is not otherwise in use by the system is used by the 
web object cache. If your system is not experiencing serious 
performance issues and this value is not stuck at 100%, the system is 
operating normally. 

Proxy Buffer Memory is one component that uses this RAM.
