migration_job/initial_sync_complete 측정항목은 특정 데이터베이스 또는 전체 마이그레이션 작업의 전체 덤프 단계가 완료된 시점을 나타냅니다. database 라벨을 적용하여 마이그레이션 수준 또는 데이터베이스 수준에서 이 측정항목을 볼 수 있습니다. 데이터베이스 라벨이 있는 경우 측정항목 값은 해당 데이터베이스의 값입니다. 라벨이 채워지지 않은 경우 측정항목 값은 전체 이전 작업에 대한 값입니다.
migration_job/max_replica_bytes_lag 측정항목에는 아직 대상에 복제되지 않은 로그 데이터의 크기가 표시됩니다. database 라벨을 적용하여 마이그레이션 수준 또는 데이터베이스 수준에서 이 측정항목을 볼 수 있습니다. 데이터베이스 라벨이 있는 경우 측정항목 값은 해당 데이터베이스의 값입니다. 라벨이 채워지지 않은 경우 측정항목 값은 전체 이전 작업에 대한 값입니다.

You can view this metric on a migration level or a database level by applying the `database` label. If the database label is present, the metric value is for that particular database. If the label is not populated, the metric value is for the entire migration job.\n- The [`migration_job/max_replica_bytes_lag`](/monitoring/api/metrics_gcp_d_h#datamigration/migration_job/max_replica_bytes_lag) metric shows the size of log data that are not yet replicated to the destination. You can view this metric on a migration level or a database level by applying the `database` label. If the database label is present, the metric value is for that particular database. If the label is not populated, the metric value is for the entire migration job.\n- The [`migration_job/max_replica_sec_lag`](/monitoring/api/metrics_gcp_d_h#datamigration/migration_job/max_replica_sec_lag) metric shows the time (in seconds) that the destination database is behind the source database. You can view this metric only at the migration level.\n\nFor more information about the Metrics Explorer, see [Create charts with Metrics Explorer](/monitoring/charts/metrics-explorer)."]]
