+## Logs
+
+Cockpit can optionally record some of its received telemetry values, which can then be turned into subtitle
+files when recording videos. 
+
+Currently the possible variables for logging are pre-defined, and the output format is determined automatically.
+If left unconfigured, the variables that are recorded by default are those from active widgets in the selected 
+[Profile](#profiles). It is possible to override which variables are logged via the configuration page, but
+custom widgets like the `VeryGenericIndicator` cannot currently be logged.

+
+Logging is at a fixed rate of 1Hz. When a video recording completes, a corresponding subtitle file is generated
+by slicing the raw log from the start to end timestamps of the video.
+
+{% note() %}
+Recorded video and subtitles are in separate files, so the browser will typically ask for permission to "download
+multiple files", which must be accepted to get access to the subtitles corresponding to a video recording.
