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.

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 - Workqueue
System Capacity- Incoming Mail
The incoming mail page shows incoming connections, the total number of incoming messages, the
average message size, and the total incoming message size. You can limit the results to the time range
that you specify. It is important to have an understanding of the trends of normal message volume and
spikes in your environment. You can use the incoming mail page to help 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 emails that are being sent from specific domains to your
network.
