Monitor migration progress

Once the bridge starts running, you can monitor the progress of your migration in the Google Workspace Migrate logs. You can filter the information to get detailed data, such as specific types of warnings or failures. You can also check the nodes to view their level of activity.

Open & monitor the logs

  1. Click Bridges. You might have to click Menu "" first.
  2. Point to the bridge, click Logs "", and select a log.
  3. (Optional) To filter the log results, got to Filter Migration summary log results and Filter other log results (below on this page).
  4. (Optional) To download the log and a bridge settings CSV file (containing details about the settings template used in the bridge), click Download ""and thenDownload logs and details.

Download the bridge reports

You can download a zip file that contains the migration summary, transaction, execution, and partition logs for the latest bridge execution. In the download, you can also review the bridge settings CSV file.

  2. Point to the bridge and click More ""and thenDownload Bridge Reports.
  3. For details about the logs, go to Types of logs (below on this page).

Types of logs

Expand section  |  Collapse all & go to top

Migration summary log

You can review a high-level overview of the content migrated in the bridge execution using the migration summary log. You’ll see the total number of transactions processed.

Migration summary data is grouped into different categories: identity or user (the default), source type, and error code. You can use the categories to identify source account data that could cause bottlenecks. For example, if you group by error code, you might detect there’s an unexpectedly high count of a single error.

To view migration summary data:

  1. In the Google Workspace Migrate platform, click Bridges.
  2. Point to your bridge and click Logs ""and thenMigration Summary.
  3. Click Down "" and select a category for Group by.
  4. Point to a record and click More ""and thenView logs.

    You can view the transaction log and detailed records of your data set, including stack traces and error codes.

Partition log

Use the Partition log to see the partitions that were created and run for the bridge.

You can filter the log by the state of each partition. To do so:

  1. Open the partition log.
  2. Click State and select the ones you want to view.
    The most significant states are:
    1. Ready—Partition is ready to begin.
    2. Processing—Partition is working.
    3. Completed—Partition’s work is complete. 

Note: For detailed information about the data migrated and whether it was successful, check the transaction and execution logs.

Execution log

You can identify any operational errors in the Execution log. The log contains a record of each step that’s required to run the bridge. You’ll see a list of the status of each operational component in the migration process. The number of failed transactions shown for a bridge on the Google Workspace Migrate platform is the sum of the errors in this log and the transaction log.

You can view all execution log entries for a partition:

  1. Open the execution log.
  2. Point to a row in the log and click ""and thenPartition transaction log

Note: You only see this option when the execution log entry is associated with a partition.

Transaction log

Use the transaction log to review details about each object processed during the bridge. You’ll see each object within the migration scope. It might take some time for the transaction log to fully load. The number of failed transactions shown for a bridge on the Google Workspace Migrate platform is the sum of the errors in this log and the execution log.

To check the detailed data for each transaction, point to the transaction and click Details "". To download the log, click Download "".

View the log in real time

During a migration, object records are constantly being written to the transaction log. You can view these log records in real time to spot check the migration and ensure there are no major problems.

To review the current stream of migrated objects in the transaction log:

  1. Open the transaction log.
  2. Click Reset to show all transactions.
  3. Choose an option (such as State or Error) to filter the transactions.

Filter by state

You can filter the transaction log by the state of each transaction:

  1. Open the transaction log.
  2. Click State and select the ones you want to view. The possible states are:
    • Prepared—Ready to begin.
    • Queued—Waiting to be processed. 
    • Processing—Preparing to write data to the target system.
    • Pending—The transaction has been processed and is waiting to be written to the target system. 
    • Completed—The process for the transaction is complete. 
    • Failed—The transaction didn't finish, due to an error. The transaction details can give you more information about the failure. To view, point to the transaction and click More ""and thenTransaction details.

      For details, go to Understand transaction details.

    • Warning—The transaction was migrated successfully but didn't complete as expected. View the warning information for details.
    • Skipped—The transaction was skipped.

      For more information, go to Troubleshoot skipped transactions.

View transactions by partition

You can view all transaction log entries for a partition:

  1. Open the transaction log.
  2. Point to a row in the log and click ""and thenPartition transaction log
Execution history log

You can use the Execution history log to see every log for every bridge that’s run. You can also see a record of every occasion that the bridge ran as a full or delta migration. To see each log in the Execution history log, point to the record of the bridge, click More ""and thenselect the log.

Monitor node status

To view the nodes, their URL, and status, open the Google Workspace Migrate platform and click Servers

You might notice that some nodes appear underutilized during a large migration. The factors that determine how work is distributed across nodes include the CPU and RAM of the node servers. Additionally, the size of scanned data per partition can impact node work distribution.

If a node becomes inoperable and its partition is incomplete, the partition rejoins the queue. Another node picks up the partition and completes the task. If this occurs, you'll see it noted in the execution log. Once you start the migration, you should not decommission any node servers, even when it looks like the nodes are not currently involved in migration tasks.
