Understanding the Email Reporting Pages
Tip
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.

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

Overall CPU Usage
Email Security appliances are 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.
