Hello there!
These online status indicators are based on a ping request performed from the server hosting your Lansweeper web console to the client asset. If the asset is a Windows computer, the NetBIOS name is pinged; if the asset is not a Windows computer, the IP address is pinged.
The ping requests are performed on demand when you open the asset's Lansweeper webpage or select the Ping Assets button in overviews. This data isn't stored in the Lansweeper database.
