How Can I Find Out Why Some Tasks in a Batch Task Failed?

After a batch task is completed, there will be result telling you how many tasks succeeded or failed. To find out why those tasks failed, you can check their result list or obsutil log file.

After a batch task is executed, its task ID will be generated. You can query the list of failed tasks in the .obsutil_output directory based on the task ID. The list is named in the cp_{failed}_report_Time_TaskId.txt format and contains detailed error information about each failed task. In addition, you can view the obsutil log file to query the error records during obsutil running. You are advised to set the log level to DEBUG for fault locating. For details about the log configuration and log path, see Log Files.
