  Web Reporting Page Descriptions
The ‘Maximum’ value indicator on the System Capacity page is the highest value seen for the specified 
period. The ‘Average’ value is the average of all values for the specified period. The period of 
aggregation depends on the interval selected for that report. For example, you can choose to see the 
Average and Maximum values for each day if the chart is for a month period.
Note
If you select Year for the time range for other reports, we recommend that you select the largest time 
range, 90 days.
System Capacity - System Load 
The first four graphs on the System Capacity window show the system load reports. These reports show 
the overall CPU usage on the appliances. AsyncOS is optimized to use idle CPU resources to improve 
transaction throughput. High CPU usage may not indicate a system capacity problem. If the high CPU 
usage is coupled with consistent, high-volume memory page swapping, you may have a capacity 
problem. This page also shows a graph that displays the amount of CPU used by different functions, 
including processing for the Web Security appliance reporting. The CPU-by-function graph is an 
indicator of which areas of the product use the most resources on your system. If you need to optimize 
your appliance, this graph can help you determine which functions may need to be tuned or disabled.
Additionally, the Response Time/Latency and Transactions Per Second graphs shows the overall 
response time (in milliseconds), and transactions per second for the date range specified in the Time 
Range drop-down menu. 
System Capacity - Network Load 
The next graphs on the System Capacity window show the outgoing connections, the bandwidth out, and 
the proxy buffer memory statistics. You can view the results for a day, week, month, or year. It is 
important to understand the trends of normal volume and spikes in your environment. 
The Proxy Buffer Memory may indicate spikes in network traffic during normal operation, but if the 
graph climbs steadily to the maximum, the appliance may be reaching its maximum capacity and you 
should consider adding capacity. 
These charts are on the same page as the charts described in 
below those charts. 
Note About Proxy Buffer Memory Swapping
The system is designed to swap proxy buffer memory regularly, so some proxy buffer memory swapping 
is expected and is not an indication of problems with your appliance. Unless the system consistently 
swaps proxy buffer memory in high volumes, proxy buffer memory swapping is normal and expected 
behavior. If your system runs with extremely high volumes, and consistently swaps proxy buffer memory 
due to the high volumes, you may need to add Web Security appliances to your network or tune your 
configuration to ensure maximum throughput to improve performance. 
Data Availability Page
The Web > Reporting > Data Availability page provides an overview of the date ranges for which 
reporting and web tracking data are available on the Security Management appliance for each managed 
Web Security appliance.
