Change logs level for a job

If you cannot locate an issue based on the logs at the INFO level, you can change the level of logs to DEBUG. This page describes how to change the level of logs for a job and provides the related limits and precautions.

Background information

The following table describes the supported log levels in ascending order of urgency.

Level	Description
TRACE	Records finer-grained information than DEBUG logs.
DEBUG	Records the status of the system.
INFO	Records important system information.
WARN	Records the information about potential issues.
ERROR	Records the information about errors and exceptions that occur.

Limits

• You can change the level of logs for a job only to the INFO or DEBUG level. If you change the level to a higher level, you may not locate issues based on the logs.

• You can change the log level of the JobManager.

• You can change only the log level of a single TaskManager at a time. You cannot change the log levels of all TaskManagers at a time. If you want to change the log levels of all TaskManagers, you must separately change the log level of each TaskManager.

Precautions

• After you change the log level to DEBUG, logs at the DEBUG, INFO, WARN, and ERROR levels are printed.

• After you change the log level to INFO, logs at the INFO, WARN, and ERROR levels are printed.

• After you change the log level, only the new logs that are generated are affected. Existing logs are not affected.

• If you set the log level to DEBUG, the performance of the job may be affected. If you do not need to locate issues, we recommend that you set the log level to INFO.
