Monitor a Sync Job
On this page
You can monitor a sync job from the History pane on the Data Migration tab. The History pane contains information about in progress, completed, and failed sync jobs.
About this Task
Sync jobs execute in a number of distinct stages, which are visible on the Job overview pane.
For example:
A snapshot sync job includes a snapshot stage and, optionally, a verification stage.
A continuous sync job includes a snapshot stage, followed by a CDC stage.
Job Overview
High-level sync job information displays in the top section of the Job overview pane.
Metric | Description |
|---|---|
Source URI | The JDBC connection string used to connect to the source relational database. |
Destination URI | The MongoDB connection string used to connect to the destination MongoDB database. |
Job Mode | Indicates if the sync job is snapshot or continuous. |

Snapshot Stage

CDC Stage
The CDC stage information is displayed in the CDC stage section of the Job overview pane. The CDC stage begins after the initial snapshot stage has completed and remains in the RUNNING status until it is explicitly completed, or the sync job encounters an unrecoverable error.
Metric | Description |

Total events seen | Number of data change events Relational Migrator has detected since the CDC stage started. |
Events in the last hour | Number of data change events Relational Migrator has detected in the last hour. |
