 ### Query Options
 
-Some datasources (e.g., Loki) allow the use of **Live** tailing to show a steady stream of log messages.
-When the panel is in **Live** mode, results are directly streamed from the datasource and the dashboard's time range is ignored.
-Note that the streaming can put extra effort on the datasource and your browser.
-Usually, the dashboard-wide refresh should be enough to get a recent set of log lines.
-
-To limit the number of lines rendered, you can use the query-wide **Max data points** setting. If it is not set, the datasource will usually enforce a limit.
