Every message in the log file has an associated severity level. The messages that are logged have the same or higher level than the configured log level. For example, the default log level is INFO, which means that messages for the following severity levels are logged: INFO, WARNING, and SEVERE.
The following table shows the severity levels in descending order of severity:
Severity level | Type of information in message | Examples of information in message |
---|---|---|
SEVERE | Errors and exceptions that occur during the execution of the server. Typically, the message includes detailed information with the stack trace that can help identify the cause of the problem. | |
WARNING | Mild problems that might require the attention of an administrator. |
|
INFO | Information that is generated during system operation. |
|
FINE | Details for debugging purposes. |

FINER | More details. |
