 profile editor leaves existing profiles unchanged.
 
+When many Graylog streams are available, use `Diagnostics -> Stream Coverage` to
+see which streams are enabled, which have profiles, how many profile fields are
+baseline-ready, how many events were fetched, and whether a stream is `ready`,
+`learning`, `missing_profile`, `no_events`, or `not_enabled`.

 Enabled streams are normalized through the same event model. Stream profiles
 define the entity, timestamp, categorical, and numeric fields used for baselines.
 The dashboard and Ollama then correlate behavior across sources, for example a
