Yes, BSN.cloud provides free, real-time access to basic health information and system diagnostics of connected players. Also available are a visual representation of player status (via the thermometer icon on the Dashboard; more info here), various types of logging, and the ability to set the frequency of log uploads.
All of these capabilities are available for both tiers of BSN.cloud (the free Control Cloud tier as well as the subscription-based Content Cloud tier) and can be accessed with BrightAuthor:connected. Those in the Control Cloud tier can also use the web interface at control.bsn.cloud.
