Diagnostics And Improvements - D-Link NetDefendOS User Manual

2.9. Diagnostics and Improvements

Overview
To help D-Link improve NetDefendOS and related services, NetDefendOS provides a feature
known as Diagnostics and Improvements. This consists of the optional ability of NetDefendOS to
automatically send informational messages back to D-Link servers about the NetDefendOS
installation.
This feature is enabled by default but can be disabled manually by the administrator, as shown in
the example at the end of this section.
Communication is Encrypted and Periodic
Communication between NetDefendOS and D-Link servers is encrypted and occurs at the
following times:
• Shortly after system startup.
• Once per day following startup.
The exception to the above are crash reports which are only sent once, after an anomalous event
occurs.
Information Sent to D-Link
If the diagnostics and improvements feature is enabled, the information returned to D-Link by
NetDefendOS can be of the following types:
• Anonymous diagnostic reporting
This information relates to the static parameters of NetDefendOS and includes the
NetDefendOS version number and the version number of any installed databases such as the
anti-virus or IDP database.
• Anonymous diagnostic reporting plus usage statistics
This is enabled by default. The usage statistics provide a higher level of detail on system
operation and includes parameters such as:
• System uptime.
• Installed RAM memory size.
• CPU load.
• RAM memory usage.
• Web content filtering statistics (if enabled).
• Crash reports
This is enabled by default and will send encrypted and anonymous information to D-Link if
an anomalous system event occurs. A crash report is only sent once after such an event and it
can help D-Link support engineers determine where in NetDefendOS a problem occurred
and why.
