Monitoring Kerio Connect

In Kerio Connect, you can:

• Monitor incoming and outgoing messages.
• View connections to services and the number of messages.
• View statistics (including antivirus and spam filter).
• View who is connected.
• Monitor the CPU and RAM usage.

Monitoring Incoming and Outgoing Messages

All messages sent or received through Kerio Connect are stored in the Kerio Connect installation directory in the store/queue subdirectory.

The default installation directories are:

• Windows: C:\Program Files\Kerio\MailServer\store\queue
• macOS: /usr/local/kerio/mailserver/store/queue
• Linux: /opt/kerio/mailserver/store/queue

Kerio Connect stores the messages in the following formats:

• The *.eml file is the message itself.
• The *.env file is the SMTP envelope of the message.

Viewing Messages in Queue

Go to Status > Message Queue > Messages in Queue tab to view messages in the queue.

In this section, you can:

• Verify whether messages are sent/received properly.
• Remove messages from the message queue.
• Immediately send messages waiting in the queue.

Processing Message Queue

When processing the message queue, Kerio Connect creates a new process for each message. This process reports all actions (such as delivery to a remote SMTP server and antivirus control) and then terminates. Multiple processes can run simultaneously.

Go to Status > Message Queue > Message Queue Processing to view the status of messages that are currently being processed.

Configuring Message Queue Parameters

In the administration interface, go to Configuration > SMTP Server > Queue Options tab.

Here you can specify:

• The maximum number of messages being delivered at a time.
• The interval in which Kerio Connect retries to deliver messages.
• The interval in which Kerio Connect sends the undelivered messages to senders.
• The interval in which senders are notified that their messages have not been delivered.
  
  
  
  

Traffic Charts

In the Kerio Connect administration interface, go to Status > Traffic Charts. Here you can view the number of connections to individual Kerio Connect services and the number of processed messages (both incoming and outgoing) for a given period in graphical format.

Viewing Statistics

In the Kerio Connect administration interface, go to Status > Statistics to view the Kerio Connect statistics. The statistics are divided into groups: Storage Occupied, Messages sent to parent SMTP server, Client POP3 statistics, etc.

For more information, click To Advanced Mode.

Viewing Users Currently Connected to Kerio Connect

Go to Status > Active Connections to view all network connections established with the server.

To view the connections established with the Kerio Connect's web interfaces and session expiry times, go to Status > Active Connections > Active Web Sessions.

Kerio Connect also allows you to view which email folders are being used by the users. To display currently opened folders, go to Status > Opened Folders.

Monitoring CPU and RAM Usage

Go to Status > System Health to view the current usage of CPU, RAM, and disk space on the machine where Kerio Connect is installed.

You can also choose a Time Interval and view the corresponding CPU and RAM usage details.

The lack of system resources may seriously affect the functionality of Kerio Connect. If these resources are permanently overloaded, click Tasks > Restart Kerio Connect and then check the usage of the system resources again.

The Support Information link generates a configuration file with all general system information and the last 100 lines of all logs. This information can be helpful when solving issues in cooperation with the Kerio support team.
