For configurations that have multiple targets, Data Replication provides a separate log for each target process of a task.

Data Replication stores the logs for the active tasks in the

DataReplication_installation

/logs directory on the system where the Server Manager for the tasks runs. When a task starts, Data Replication creates a directory that is named for the current date in the

DataReplication_installation

/logs subdirectory, if the directory does not already exist. Within this current-date directory, Data Replication creates a subdirectory for each task that runs, using the task identifier as the subdirectory name. When a task completes, the Server Manager transmits the log files to the Server Manager Main server. The Server Manager Main server stores the log files locally in the

DataReplication_installation

/logs directory, using a subdirectory hierarchy that is identical to that on the system where the task runs.

Every hour, the Server Manager scans the

DataReplication_installation

/logs subdirectories that contain log files and purges the old log files.

The Server Manager retains log files based on the following criteria:

For tasks that run as a part of a schedule, the Server Manager uses the schedule
Keep logs, days
setting to determine the period for which to retain the log files. By default, the Server Manager stores the log files for 30 days.
For a task that runs outside of a schedule, the Server Manager retains log files for 30 days after the task completes.
If you delete a schedule, the Server Manager immediately purges the log files for all of the tasks in the schedule.

For convenience, you can view the log files for tasks from the

Server Manager

tab >

Schedules

view or the

Server Manager

tab >

Event Viewer

view >

Logs of Schedules

subtab in the Data Replication Console. After the Server Manager purges the log files, they are no longer available for viewing in the Data Replication Console.

For the InitialSync and Applier tasks, Data Replication periodically logs processing status information.

For the InitialSync task, Data Replication updates processing statistics at 10-second intervals by default. You can use the initial.print_statistics_interval runtime parameter to change the interval. These statistics include the number of processed rows, the total number of rows to be loaded, and the estimated time for processing to complete.
For the Applier task, Data Replication updates the number of processed rows at 5-minute intervals by default. You can use the apply.print_statistics_interval runtime parameter to change the interval. Data Replication also logs a warning message when the Applier task detects significant performance degradation.
