 `path_targets` uses [doublestar][] style paths.
 * `/tmp/**/*.log` will match all subfolders of `tmp` and include any files that end in `*.log`.
 * `/tmp/apache/*.log` will match only files in `/tmp/apache/` that end in `*.log`.
 * `/tmp/**` will match all subfolders of `tmp`, `tmp` itself, and all files.
+* When `ignore_older_than` is set to "0s" the component will not ignore any files
