Chapter 4 Using Centralized Email Security Reporting
Understanding the Email Reporting Pages
Note
If a message is released from the quarantine into the work queue, the “average time in work queue”
metric ignores this time. This prevents double-counting and distorted statistics due to extended time
spent in a quarantine.

The report also shows the volume of messages in the work queue over a specified time period, and it
shows the maximum messages in the work queue over the same time period. The graphical
representation of the maximum messages in the work queue also shows the work queue threshold level.
shows the maximum messages in the work queue over the same time period. The graphical
representation of the maximum messages in the work queue also shows the work queue threshold level.
Occasional spikes in the Workqueue graphs are normal and expected. If the messages in the work queue
remain higher than the configured threshold for a long duration, this may indicate a capacity issue. In
this scenario, consider tuning the threshold level or review the system configuration.

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.
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

outgoing destinations data to view the trends in volumes of email messages that are sent from specific
domains or IP addresses.
