监控自动种子设定
系统动态管理视图
sys.dm_hadr_automatic_seeding
在主要副本上，查询 sys.dm_hadr_automatic_seeding 以检查自动种子设定过程的状态。 对于每个种子设定过程，该视图都将返回一行。 例如：
SELECT start_time,
completion_time,
is_source,
current_state,
failure_state,
failure_state_desc,
error_code
FROM sys.dm_hadr_automatic_seeding
sys.dm_hadr_physical_seeding_stats
在主要副本上，查询 sys.dm_hadr_physical_seeding_stats DMV 以查看当前运行的每个种子设定过程的物理统计信息。 种子设定正在运行时，以下查询将返回多行：
SELECT local_database_name,
role_desc,
internal_state_desc,
transfer_rate_bytes_per_second,
transferred_size_bytes,
database_size_bytes,
start_time_utc,
end_time_utc, estimate_time_complete_utc,
total_disk_io_wait_time_ms,
total_network_wait_time_ms,
is_compression_enabled
FROM sys.dm_hadr_physical_seeding_stats
