How to Interpret the Data You See on the System Capacity Page
When choosing time ranges for viewing data on the System Capacity page, the following is important to
remember:
remember:
•
Day Report— The Day report queries the hour table and displays the exact number of queries that
have been received by the appliance on an hourly basis over a 24 hour period. This information is
gathered from the hour table.
have been received by the appliance on an hourly basis over a 24 hour period. This information is
gathered from the hour table.
•
Month Report— The Month report queries the day tables for the 30 or 31 days (dependent on the
number of days in the month), giving you an exact report on the number of queries over 30 or 31
days. Again, this is an exact number.

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.

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.

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.
