+There are also some uniq features which are not directly available via

+So you can see, which index will be rolled over when. Note the
+**VIRTUAL-AGE** field however: it is calculated from the current
+storage usage of the index in relation to rollover max shard size. So
+you can see, when an index will be rolled over either because it aged
+out or because its storage exceeded the limit.

 Please note, that `esctl` is still in its early stages and things are
 changing heavily every now and then. New commands are being added
 constantly as well.
