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.

System Capacity – Workqueue
The System Capacity – Workqueue page shows the volume of messages in work queues over a specified
time period. It also shows the maximum messages in work queues over the same time period. You can
view data for a day, week, month, or year. Occasional spikes in the Workqueue graphs are normal and
expected. If the spikes occur with increasing frequency and are maintained over a long period of time,
this may indicate a capacity issue. When reviewing the work queue page, you may want to measure the
frequency of work queue backups, and take note of work queue backups that exceed 10,000 messages.

System Capacity – Incoming Mail
The System Capacity – Incoming Mail page shows incoming connections, the total number of incoming
messages, the average message size, and the total incoming message size. You can view the results for
a day, week, month, or year. It is important to understand the trends of normal message volume and
spikes in your environment. You can use the System Capacity – Incoming Mail page to track volume
growth over time and plan for system capacity. You might also want to compare the incoming mail data
with the sender profile data to view the trends in volumes of email messages that are sent from specific
domains to your network.

Note
An increased number of incoming connections may not necessarily affect system load.
System Capacity – Outgoing Mail
The System Capacity – Outgoing Mail page shows outgoing connections, the total number of outgoing
messages, the average message size, and the total outgoing message size. You can view the results for a
day, week, month, or year. It is important to understand the trends of normal message volume and spikes
in your environment. You can use the System Capacity – Outgoing Mail page to track volume growth

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
