Chapter 3 Using Centralized Email Reporting
System Capacity – System Load
The system load report shows the overall CPU usage on the Email Security
appliances. AsyncOS is optimized to use idle CPU resources to improve message
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 mail processing, spam and
virus engines, reporting, and quarantines. 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.
