Overview
The following table lists and describes migration job metrics for Database Migration Service.
| Migration metric | Description |
|---|---|
| Replication delay | Represents how much time the destination database is behind the source database. Use this metric when considering performing a promotion of a continuous migration. Replication delay should be zero at the time of the promotion in order to avoid data loss. Note this metric is only relevant in the change data capture (CDC) phase. For more information on job promotion, see Promote a migration. |
| Storage usage | Reflects how many GB are currently being used by the destination Cloud SQL instance. Use this metric to get a rough indication of migration job progress. |
