To review details about the migration job, follow these steps:
In the Google Cloud console, go to the Migration jobs page.
On the Jobs tab, click the name of your migration job.
The migration job details page opens.
The details page includes the following metrics:
- Migration job metadata, such as the display name, ID, migration type, source connection profile, source database engine, destination, connectivity method, date and time that the migration job was created, and how long the migration job is running.
- Replication delay: The lag (in seconds) between the existing data in the destination database and the data in the source database being replicated into the destination database.
- Storage usage: The amount of storage used.
- Migration job status and substatus, and additional information. Different actions are available depending on the migration job's status and substatus.
Migration job statuses
The following table lists, describes, and provides user actions for migration job statuses for Database Migration Service.
| Migration job status | Description | Possible substatus | Possible user actions |
|---|---|---|---|
| Not started | The migration job is ready but still not running. This status is relevant if the migration job was created but wasn't started. | None. | Start. Delete. |
| Starting... | The migration job is in the process of being started. This is an intermediate status that occurs when a migration job is
started. Starting the migration job takes between a few seconds and a few
minutes. The status changes to Running. |
None. | Delete. |
| Running | The migration job is actively running. If you want to edit the data dump parallelism level of a running migration job, click Edit. You must restart the job after you make the changes. For more information about parallelism, see Specify information about the source connection profile. |
CDC, promote in progress. | Stop. Promote. Delete. |
| Running with errors | This status means that Database Migration Service encountered errors with
your migration. Faulty operations will be retried,
and errors clear automatically once the underlying issue is resolved.
Database Migration Service continues migrating data unaffected by the error. |
CDC. | Stop. Restart. Promote (when the job is in the CDC phase). |
| Completed | The migration job is completed. In the continuous migration type, this occurs after a successful promotion. | None. | Delete. |
| Failed | The migration job failed because of an error. Based on the type of error, the migration job may resume automatically, after the issue is fixed. Otherwise, the failure is unrecoverable, and the migration job needs to be restarted. | The last status before the migration job failed. Failed in CDC, Failed in full dump. | Restart. Delete. Promote. |
| Restarting | The migration job is in the process of being restarted. | None. | Delete. |
| Stopped | The migration job is stopped. | The last status before the migration job has stopped: Stopped in CDC. | If in the CDC phase, then the migration job can be resumed, promoted, or deleted. |
| Resuming | The migration job is in the process of being resumed. | None. | Delete. |
| Stopping... | The migration job is in the process of stopping after Stop was
invoked. This is an intermediate status that occurs when a user stops a
migration job. Stopping the job takes around a
minute, during which the status is Stopping. Subsequently, the status
changes to Stopped. |
None. | Delete. |
Migration job metrics
Database Migration Service collects and displays migration job metrics that represent the health and progress of your data migration process.
The following table lists and describes the migration job metrics that you can view on the migration job details page:
| Migration metric | Description |
|---|---|
| Replication delay | Represents how many bytes the destination database is behind the source database. Use this metric when you consider 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 being used by the destination Cloud SQL instance. Use this metric to get a rough indication of migration job progress. |
