| Configuration Page | Reports > Reports > SMTP Mail |
Summary Statistics
Received
The number of mail messages received by the server. Each mail message may have multiple recipients (e.g. a mail might be sent to marsha@example.com, jan@example and cindy@example.com)
Delivered
The number of mail messages delivered to a mailbox. Using the above example, you would get 3 "delivered messages" for the 1 "received message".
Forwarded
The number of forwarded messages using Postfix internal forward mechanism.
Deferred
The number times a message was queued. On every attempt to deliver mail, the deferred count increases by one, i.e. a single message can generate may deferred counts. Most of this traffic is caused by bounced spam messages going back to non-existent mail servers.
Bounced
The number of bounced messages. Most of this is caused by spammers using dictionary attacks (guessing e-mail addresses).
Rejected
Similar to a bounce, but caused by misbehaving mail servers or messages (e.g. a missing "From" e-mail address) or the mail servers internal filtering mechanism.
Held
The number of messages held. An administrator basically put aside messages in the mail queue for later delivery. This requires action on the command line.
Discarded
The number of messages discarded. The Postfix mail server can be configured to discard mail messages. By default, CommGate does not use this feature.

Statistics
Overview
| System Statistics | Information |
|---|---|
| Description | Historical information on system performance. |
| Package Name | cc-mrtg |
| Configuration Page | Reports > System Information > Statistics |
Installation
If you did not select this module to be included during the installation process, you must first install the module.
Statistics
The charts shown in the statistics page show the following information:
- Maximum value over the period (e.g. one day)
- Average value over the period
- Current value
Load
The system load is a measure of how the overall system is performing. A common misconception is that the system load is a measure of CPU usage. However, a high system load can be caused by excessive hard disk access or other types of bottlenecks in the overall system.
Two different trend lines are shown on this chart. The green line indicates the average system load for a given 5-minute time period. The blue line indicates the average system load for a given 15-minute time period.
A sustained load above 200 on the chart indicates an overloaded system (occasional spikes above this number are normal).
The system load displayed on the charts is multiplied by 100. For instance, if you see a load of 53 in the chart, then the load is really 0.53.
Open Connections
This statistic shows the number of open network connections to your system. For instance, an end user fetching their e-mail from the server will open one (or more) network connections. If your system comes under an unwanted attack, you will likely see a large spike in open connections.
Processes
The number of processes running on your system.
Swap Memory
Swap memory usage is an indirect indicator of how well your system is managing RAM (physical) memory. The green background in this chart (if shown) is the amount of swap memory available. The blue line indicates the amount of swap memory used. If the blue line sustains a level of 75% of the total swap memory available, then you need to take action:
- Disable unused software/services running on the system
- Investigate potential software bugs/issues
- Add more RAM
The intrusion detection system and content filter system use quite a bit of system resources.
Warning! On a Linux system, all unused RAM is used to optimize file access. Do not be surprised to find your RAM usage at 95% or higher.
Uptime
The uptime charts how long your system has been running without a reboot.

Web Proxy
Overview
| Web Proxy Reports | Information |
|---|---|
| Description | A report displaying information on proxy and content filter usage. |
| Package | cc-squid |
| Configuration Page | Reports > Reports > Web Proxy |
In CommGate versions prior to 4.0, the web proxy reports were generated by a package called cc-sarg. In 4.0, the reports are created through the CommGate API using a dedicated MySQL database. This makes extraction of the report logs simple to do in the event other report medium (ie. PDF) or statistics are required.
