This API will return all stats related to {ccr}. In particular, this API returns stats about auto-following, and returns the same shard-level stats as in the <>. ==== Request ////////////////////////// [source,js] -------------------------------------------------- PUT /follower_index/_ccr/follow { "remote_cluster" : "remote_cluster", "leader_index" : "leader_index" } -------------------------------------------------- // CONSOLE // TESTSETUP // TEST[setup:remote_cluster_and_leader_index] [source,js] -------------------------------------------------- POST /follower_index/_ccr/pause_follow -------------------------------------------------- // CONSOLE // TEARDOWN ////////////////////////// [source,js] -------------------------------------------------- GET /_ccr/stats -------------------------------------------------- // CONSOLE ==== Results This API returns the following information: `auto_follow_stats`:: (object) an object representing stats for the auto-follow coordinator This object consists of the following fields: `auto_follow_stats.number_of_failed_follow_indices`:: (long) the number of indices that the auto-follow coordinator failed to automatically follow; the causes of recent failures are captured in the logs of the elected master node, and in the `auto_follow_stats.recent_auto_follow_errors` field `auto_follow_stats.number_of_failed_remote_cluster_state_requests`:: (long) the number of times that the auto-follow coordinator failed to retrieve the cluster state from a remote cluster registered in a collection of auto-follow patterns `auto_follow_stats.number_of_successful_follow_indices`:: (long) the number of indices that the auto-follow coordinator successfully followed `auto_follow_stats.recent_auto_follow_errors`:: (array) an array of objects representing failures by the auto-follow coordinator `follow_stats`:: (object) an object representing shard-level stats for follower indices; refer to the details of the response in the <> ==== Authorization If the {es} {security-features} are enabled, you must have `monitor` cluster privileges on the cluster that contains the follower index.
