[[ccr-auto-follow]]
=== Manage auto-follow patterns
To replicate time series indices, you configure an auto-follow pattern so that
each new index in the series is replicated automatically. Whenever the name of
a new index on the remote cluster matches the auto-follow pattern, a
corresponding follower index is added to the local cluster.

Auto-follow patterns are especially useful with
<<index-lifecycle-management,{ilm-cap}>>, which might continually create
new indices on the cluster containing the leader index.

[[ccr-access-ccr-auto-follow]]
To start using {ccr} auto-follow patterns, access {kib} and go to
*Management > Stack Management*. In the side navigation, select
*Cross-Cluster Replication* and choose the *Auto-follow patterns* tab

[[ccr-auto-follow-create]]
==== Create auto-follow patterns
When you <<ccr-getting-started-auto-follow,create an auto-follow pattern>>,
you are configuring a collection of patterns against a single remote cluster.
When an index is created in the remote cluster with a name that matches one of
the patterns in the collection, a follower index is configured in the local
cluster. The follower index uses the new index as its leader index.

[[ccr-auto-follow-retrieve]]
==== Retrieve auto-follow patterns
To view existing auto-follow patterns and make changes to the backing
patterns, <<ccr-access-ccr-auto-follow,access {kib}>> on your _remote_ cluster.

Select the auto-follow pattern that you want to view details about. From there,
you can make changes to the auto-follow pattern. You can also view your
follower indices included in the auto-follow pattern.
