The Row-Verification page of the O&M Monitoring module of OceanBase Migration Service (OMS) allows you to view the name, region, task name, task type, and status of a Row-Verification component. This helps you assess the running status of the Row-Verification component.

Procedure

Log in to the OMS console.
In the left-side navigation pane, choose OPS & Monitoring > Component.
On the Component page, click the Row-Verification tab.
On the Row-Verification page, view the information about the target Row-Verification component.

You can also search for the target Row-Verification component by name, data validation task name, or IP address.

View the basic information about the target Row-Verification component.

Parameter	Description
Name	The name of the Row-Verification component. Hover the pointer over the Row-Verification name and click the copy icon to copy the name.
Region	You can filter Row-Verification components by region.
Task Name	The name of the data validation task. After you click a task name, you can directly jump to the details page of the task.
Task Type	The task type of the Row-Verification component.
Status	The status of the Row-Verification component. Valid values: Initialize, Running, Completed, Exception, and Stopped.
Action	You can perform the View Logs operation on a Row-Verification component.
