Monitoring a Synchronization Task

Scenarios

After a synchronization task is started, you can view the synchronization progress and details at any time.

Procedure

Sign in to the console and go to the OMS page.
In the navigation pane on the left, choose Synchronization Tasks.

Click the task ID and view the task progress. For details about the parameters, see Table 1.

**Table 1** Monitoring data of a synchronization task
Parameter	Description
Requested Objects (This Month)	Specifies the number of objects covered by the synchronization requests received from the source platform this month.
Synced Objects (This Month)	Synced Specifies the number of objects that have been synchronized this month. You can view the list of synchronized object in the destination bucket. Failed Specifies the number of objects that failed to be synchronized this month. You can view the list of failed objects in the destination bucket. Ignored Number of objects that have been ignored this month. You can view the list of ignored objects in the destination bucket. NOTE: If there is an object in the destination bucket with the same name and size as one in the source bucket, but the last modification time of the destination object is later than that of the source object, the source object will be ignored during synchronization.
Synced Object Size (This Month)	Specifies the total size of objects that have been synchronized in this month.
Object Lists	OMS records objects that are successfully synchronized, failed to be synchronized, and are ignored in three separate lists and stores these lists in the destination bucket. You can use these lists to verify the numbers and names of the synchronized, failed, and ignored objects. For details, see Table 2.
Synchronization API URL	Specifies the address for receiving synchronization requests from the source platform. These requests will trigger data synchronizations. For details about the OMS synchronization API, see Creating a Synchronization Event.

**Table 2** Object lists
Object Type	Directory	List Content
Synced objects	oms/sync_task/Synchronization task ID/success_object_lists	Occurrence times (in local UTC), non-URL-encoded names of synchronized objects, and object sizes (in bytes)
Failed objects	oms/sync_task/Synchronization task ID/failed_object_lists For example, oms/sync_task/Synchronization task ID/failed_object_lists/oms-task-sync-test-20210107111623197_596 NOTE: This directory stores the list of objects that failed to be synchronized during the migration. oms/sync_task/Synchronization task ID/failed_object_lists/creation_failures For example, oms/sync_task/Synchronization task ID/failed_object_lists/creation_failures/1609833838031_5ff41d6e85e877149d44bb55_4.failed_list.txt NOTE: This directory stores the list of objects that fail to be migrated due to task creation failures. Task creation may fail if the account is in arrears, frozen, or does not have the required permissions.	Failure cause, occurrence times (in local UTC), URL-encoded and non-URL-encoded names of failed objects, and error codes returned by source SDKs
Ignored objects	oms/sync_task/Synchronization task ID/skip_object_lists	Occurrence times (in local UTC), non-URL-encoded names of ignored objects, and object sizes (in bytes)
Objects to be synchronized	oms/sync_task/Synchronization task ID/object_lists	Names of objects to be synchronized NOTE: OMS automatically records the names of objects to be synchronized covered by the received synchronization requests in .txt files, and stores the files in the oms/sync_task/Synchronization task ID/object_lists directory of the destination bucket.
