Using Scan Mode
When the checkboxes of two or more target devices are selected in the DSView 3.0 Explorer, the
Scan button will become available. If the Scan button is clicked, Scan mode will be started and the
Video Viewer windows will appear in the Thumbnail Viewer. A series of thumbnail frames appear
in the Thumbnail Viewer, each containing a small, scaled, non-interactive version of a target device
screen image.
The Scan mode moves from one thumbnail image to the next, logging into a device and displaying
an updated device image for a specified length of time (View Time Per Server), before logging out
of that device and moving on to the next thumbnail image. You may also specify a scan delay
between thumbnails (Time Between Server). During the delay, you will see the last thumbnail
image for all devices in the scan sequence, though you won’t be logged into any devices.
When you first launch the Thumbnail Viewer, each frame will be filled with a white background
until a device image is displayed. An indicator light at the bottom of each frame displays the device
status. The default thumbnail size is based on the number of devices in the scan list.
Scan mode has a lower priority than an active connection. If you or another DSView user are
connected to a device, that device will be skipped in the scan sequence, and Scan mode will
proceed to the next device unless the Shared Connections Automatically option has been selected,
in which case target devices may be shared and will not be skipped in the scan sequence. No login
error messages will appear. After your interactive session is closed, the thumbnail will be included
in the scan sequence again.
You may disable a device thumbnail from the scan sequence. The thumbnail image remains, but it
is not updated until it is once again enabled.
When running Scan Mode, it is recommended that the following audit log events (enabled by
default) are disabled in the DSView system:
• Appliance Change Of State
• Appliance Viewer Session Started
• Appliance Viewer Session Stopped
• Viewer Session Started
• Viewer Session Stopped
Each thumbnail scan will result in the logging of the above audit log events. The audit log could
grow to a huge size if the events are enabled and Scan Mode is left running continuously for a
length amount of time.
