Viewing System Status and Statistics
Viewing System Statistics
The BASIC-->Status page provides email statistics, system environmental conditions and hourly and
daily email statistics.
Email Statistics
The following table describes the email statistics displayed on the BASIC-->Status page.
Performance Statistics
This section on the BASIC-->Status page displays system environmental conditions, such as:
■ Mail queue size for inbound and outbound messages.
The mail queue size is displayed as a ratio, such as (10/5), with the first statistic representing the
number of inbound mail and the second representing the number of outbound mail in the queue.
■ Current state of the system fans, processor and redundancy (if applicable).
■ Average amount of delay (latency) it takes the system to filter incoming email
■ How long ago the last message was delivered.
Information is displayed in red when a value exceeds the normal threshold.
Note: Only the Barracuda Spam Firewall 400 and 600 come with redundant disks; therefore, the
redundancy statistics do not appear for the 200 and 300 models.
The firmware and mail/log storage shows the percent of space used on each partition. The Barracuda
Spam Firewall emails a system alert when utilization approaches 90% on either of these partitions.
Contact Barracuda Networks technical support if a partition reaches this threshold.
Hourly and Daily Mail Statistics
Shows the number of messages blocked, quarantined, and allowed for the last 25 days and 24 hours.
Statistic Description
Blocked Number of virus and spam messages blocked by the system.
Blocked: Virus Number of virus messages blocked by the system.
Quarantined Number of messages quarantined by the system. This includes messages sent
to the global quarantine address and the number of messages quarantined by
users. By default, the system does not quarantine messages. To turn on the
quarantine feature, refer to Setting Up Quarantine on page 29.
Allowed: Tagged Number of messages tagged by the system. Tagged messages have their
subject line modified based on the settings on the Spam Scoring page
(described on page 28).
Allowed Number of messages delivered to the intended recipient without being blocked
or modified.
Total Statistics for the system since installation or the last reset.
Today Statistics for the current calendar day (from midnight to midnight).
