CcrShardStats [interface-CcrShardStats]

Name	Type	Description
bytes_read	long	The total of transferred bytes read from the leader. This is only an estimate and does not account for compression if enabled.
failed_read_requests	long	The number of failed reads.
failed_write_requests	long	The number of failed bulk write requests on the follower.
fatal_exception	ErrorCause
follower_aliases_version	VersionNumber	The index aliases version the follower is synced up to.
follower_global_checkpoint	long	The current global checkpoint on the follower. The difference between the leader_global_checkpoint and the follower_global_checkpoint is an indication of how much the follower is lagging the leader.
follower_index	string	The name of the follower index.
follower_mapping_version	VersionNumber	The mapping version the follower is synced up to.
follower_max_seq_no	SequenceNumber	The current maximum sequence number on the follower.
follower_settings_version	VersionNumber	The index settings version the follower is synced up to.
last_requested_seq_no	SequenceNumber	The starting sequence number of the last batch of operations requested from the leader.
leader_global_checkpoint	long	The current global checkpoint on the leader known to the follower task.
leader_index	string	The name of the index in the leader cluster being followed.
leader_max_seq_no	SequenceNumber	The current maximum sequence number on the leader known to the follower task.
operations_read	long	The total number of operations read from the leader.
operations_written	long	The number of operations written on the follower.
outstanding_read_requests	integer	The number of active read requests from the follower.
outstanding_write_requests	integer	The number of active bulk write requests on the follower.
read_exceptions	CcrReadException[]	An array of objects representing failed reads.
remote_cluster	string	The remote cluster containing the leader index.
shard_id	integer	The numerical shard ID, with values from 0 to one less than the number of replicas.
successful_read_requests	long	The number of successful fetches.
successful_write_requests	long	The number of bulk write requests run on the follower.
time_since_last_read_millis	DurationValue<UnitMillis>	The number of milliseconds since a read request was sent to the leader. When the follower is caught up to the leader, this number will increase up to the configured read_poll_timeout at which point another read request will be sent to the leader.
time_since_last_read	Duration
total_read_remote_exec_time_millis	DurationValue<UnitMillis>	The total time reads spent running on the remote cluster.
total_read_remote_exec_time	Duration
total_read_time_millis	DurationValue<UnitMillis>	The total time reads were outstanding, measured from the time a read was sent to the leader to the time a reply was returned to the follower.
total_read_time	Duration
total_write_time_millis	DurationValue<UnitMillis>	The total time spent writing on the follower.
total_write_time	Duration
write_buffer_operation_count	long	The number of write operations queued on the follower.
write_buffer_size_in_bytes	ByteSize	The total number of bytes of operations currently queued for writing.
