 In Tail mode, you might want to exclude gzipped files:
 [source,ruby]
     exclude => "*.gz"

+[id="plugins-{type}s-{plugin}-exit_after_read"]
+===== `exit_after_read`
+
+  * Value type is <<boolean,boolean>>
+  * Default value is `false`
+
+This option can be used in `read` mode to enforce closing all watchers when file gets read.
+Can be used in situation when content of the file is static and won't change during execution.
+When set to `true` it also disables active discovery of the files - only files that were in 
+the directories when process was started will be read.
+It supports `sincedb` entries. When file was processed once, then modified - next run will only
+read newly added entries.
