Note that in the Network View, an icon appears next to each item in the results list, to identify the type of device. Depending on whether the agent is installed, the device is currently connected, the health status, etc., a tiny overlay may also appear on or next to the device icon after you have clicked on it.
You can update the agent and health status for devices one at a time as you select
them in the Network View, or for all of the visible devices in the Network View
at the same time. You can also update a device's status by selecting it and clicking
the Refresh toolbar button.
NOTE: Icon display quality
These high-color icons require at least a 16-bit color-depth setting. If the icons in your console appear out of focus, change your color settings in the Windows Display Properties.
