A progress dialog box opens followed by a Diagnostics message dialog box. - To close the message dialog box, click OK.
Support Access for Diagnostics
Support Access is a secure method that WatchGuard Technical Support can use to get limited access to the operating system of your instance of WatchGuard Dimension.
If you contact WatchGuard Technical Support for assistance, your Technical Support representative could ask for Support Access to diagnose and troubleshoot problems with your Dimension system. Enable the Support Access for Diagnostics feature only when directed to do so by a WatchGuard Technical Support representative.
To connect to Dimension, a remote support representative must have a secure certificate and must be able to make an SSH connection to Dimension over the port you specify in the Support Access for Diagnostics settings. If your instance of Dimension is behind a gateway Firebox, you must also configure your gateway Firebox to allow access from WatchGuard Technical Support. Your support representative will provide instructions to correctly configure your gateway Firebox.
In the Support Access for Diagnostics section, you can enable or disable the Support Access feature and specify the port WatchGuard Technical Support can use to connect to your Dimension system.
- Click Configure.
The Support Access for Diagnostics dialog box opens. - Select the Enable Support Access check box.
- To use a port other than the default port (22), in the Port text box, type another port number.
- Click Save.
System Package Update
If your WatchGuard Support representative finds an issue with your Dimension system that can be resolved with an update to the Dimension system package, your representative might instruct you to update the system package to another version.
To update the system package, in the Update System Package section:
- Click Update.
- In the System Update text box, type the name of the system package to update.
- Click Update.

Process list
Process ID, the name of the process, and the status of the process.
Memory and load average
Statistics on the memory use (shown in bytes of memory) and load average of Dimension. The load average has three values that typically show an average over the last minute, 5 minutes, and 15 minutes. Values over 1.00 (100%) indicate some threads are queued until resources are available. (A system load that exceeds 1.00 does not mean the system is overloaded.)
Disk Usage
The amount of space on the Dimension instance that is in use.
Mount Points
The mount point details for Dimension connections to a file system.
Interfaces
Each Dimension interface is included, with information about the interface type configuration (external, trusted, or optional), interface status, and packet count. For active trusted or optional interfaces, if IPv6 has been enabled for the interface, both the IPv4 and IPv6 address information is included.
Routes
The Routes section includes details for the Kernel IP routing table on Dimension.
ARP table
ARP table on Dimension. The ARP table is used to match IP addresses to hardware addresses.
DNS Servers
Address information for the DNS servers.
NTP

Dimension Server Tasks
On the Dimension Server tab, you can review the process information and log messages for the Dimension server, and the Dimension task history.
Process Information
The Process Information includes these details:
CPU
The percentage of the Dimension CPU cores that the Dimension server processes currently use.
Because each CPU core can run at 100%, if the server processes use both CPU cores, the maximum is 200%. To see the sum of the maximum amount of available bandwidth on the CPU cores that the web server processes can use, place your cursor over 
.
Memory
The amount of memory on the Dimension system that the process currently uses.

Review the Status of the Email Server
In the Email Status section, you can see the current status of the email server and how many email notification messages from Dimension are in the email queue.
Normally, the Dimension email server sends messages as soon as they are generated. If there is a problem with the email server that causes the messages not to send, the messages are added to the email queue. When this occurs, the Dimension administrator can either wait for the email server to be available again and then send all the messages in the queue, or remove all the messages from the queue.
To send all messages that are in the email queue, click Flush Queue.
The Dimension email server attempts to send the messages again.
To remove all messages from the queue, click Purge Queue.
The Dimension email server removes all messages from the queue, and the Queue status changes to Empty.
Run Email Server Diagnostics
To verify that the mail server is available to send notification email messages when they are generated, you can run a diagnostic test of the email server.
To run email diagnostics:
- Click Test Email.
The Send test email dialog box opens.
- In the Send Email To text box, type the destination address of the test email message.
This is typically the Dimension Administrator. - In the Send Email From text box, type the source address of the test email message.
This is typically the address of the email server - In the Subject text box, type the subject line for the email message.
- Click Send Email.
The email server sends the test email and Message Sent appears adjacent to Test Email.
