NetHomeServer always keep a rolling log on disk about events in the system. Now the last 50 rows of this log (since last restart) is also available in the GUI via the settings page and via a link on the top right of the screen. The log contains information messages but also warnings about configuration issues or low battery warning for sensors, for example the UPM temperature sensors. If a warning message is present in the last 50 log rows a small warning triangle is presented next to the log link on the screen, as shown in the picture above. This is now available in the nightly build.
