| Description | A description for this Log Publisher |
| Default Value | None |
| Allowed Values | A string |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
| Description | Indicates whether the Log Publisher is enabled for use. |
| Default Value | None |
| Allowed Values | true false |
| Multi-Valued | No |
| Required | Yes |
| Admin Action Required | None. Modification requires no further action |
| Description | Specifies the default severity levels for the logger. |
| Default Value | fatal-error severe-warning severe-error |
| Allowed Values | all - Messages of all severity levels are logged. none - No messages of any severity are logged by default. This value is intended to be used in conjunction with the override-severity property to define an error logger that will publish no error message beside the errors of a given category. fatal-error - The error log severity that is used for messages that provide information about fatal errors which may force the server to shut down or operate in a significantly degraded state. info - The error log severity that is used for messages that provide information about significant events within the server that are not warnings or errors. mild-error - The error log severity that is used for messages that provide information about mild (recoverable) errors encountered during processing. mild-warning - The error log severity that is used for messages that provide information about mild warnings triggered during processing. notice - The error log severity that is used for the most important informational messages (i.e., information that should almost always be logged but is not associated with a warning or error condition). severe-error - The error log severity that is used for messages that provide information about severe errors encountered during processing. severe-warning - The error log severity that is used for messages that provide information about severe warnings triggered during processing. debug - The error log severity that is used for messages that provide debugging information triggered during processing. |
| Multi-Valued | Yes |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
| Description | Specifies the override severity levels for the logger based on the category of the messages.

| Description | Indicates whether the log should be cryptographically signed so that the log content cannot be altered in an undetectable manner. Log file signatures can be validated using the validate-file-signature tool provided with the server. Note that when enabling signing for a logger that already exists and was enabled without signing, the first log file will not be completely verifiable because it will still contain unsigned content from before signing was enabled. Only log files whose entire content was written with signing enabled will be considered completely valid. For the same reason, if a log file is still open for writing, then signature validation will not indicate that the log is completely valid because the log will not include the necessary "end signed content" indicator at the end of the file. |
| Default Value | false |
| Allowed Values | true false |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | The File Based Error Log Publisher must be disabled and re-enabled for changes to this setting to take effect. This modification requires that you disable and then re-enable this component for the change to take effect |
| Description | Indicates whether log messages should include the product name for the Metrics Engine. |
| Default Value | false |
| Allowed Values | true false |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
| Description | Indicates whether log messages should include the instance name for the Metrics Engine. |
| Default Value | false |
| Allowed Values | true false |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
| Description | Indicates whether log messages should include the startup ID for the Metrics Engine, which is a value assigned to the server instance at startup and may be used to identify when the server has been restarted. |
| Default Value | false |
| Allowed Values | true false |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
asynchronous (Advanced Property)
| Description | Indicates whether the File Based Error Log Publisher will publish records asynchronously. |
| Default Value | false |
| Allowed Values | true false |
| Multi-Valued | No |
| Required | Yes |
| Admin Action Required | None. Modification requires no further action |
queue-size (Advanced Property)
| Description | The maximum number of log records that can be stored in the asynchronous queue. The server will continuously flush messages from the queue to the log. That is, it does not wait for the queue to fill up before flushing to the log. Lowering this value can impact performance. |
| Default Value | 10000 |
| Allowed Values | An integer value. Lower limit is 1000. Upper limit is 100000 . |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | The File Based Error Log Publisher must be restarted if this property is changed and the asynchronous property is set to true. |
time-interval (Advanced Property)
| Description | Specifies the interval at which to check whether the log files need to be rotated. |
| Default Value | 5s |
| Allowed Values | A duration. Lower limit is 1 milliseconds. |

| Required | No |
| Admin Action Required | None. Modification requires no further action |

| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
auto-flush (Advanced Property)
| Description | Specifies whether to flush the writer after every log record. If the asynchronous writes option is used, the writer is flushed after all the log records in the queue are written. |
| Default Value | true |
| Allowed Values | true false |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
compression-mechanism (Advanced Property, Read-Only)
| Description | Specifies the type of compression (if any) to use for log files that are written. Note that this setting cannot be changed once the logger has been created, because of the possibility of mixing compressed and uncompressed data in the same file. Further, because it is difficult to append to a compressed file, any existing active log file will automatically be rotated when the server is started. If compressed logging is used, it may also be desirable to have another logger enabled that does not use compression. The rotation and retention policies for the uncompressed logger can be configured to minimize the amount of space it consumes, but having ready access to information about recent operations in uncompressed form may be convenient for debugging purposes. Alternately, you could consider having the uncompressed logger defined but not enabled so that it can be turned on as needed for debugging such problems. |
| Default Value | none |
| Allowed Values | none - No compression will be performed. gzip - Compress file data using gzip with the default compression level. If this compression level is specified, then files will automatically be given a ".gz" extension. |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
include-thread-id (Advanced Property)
| Description | Indicates whether log messages should include the thread ID for the Metrics Engine in each log message. This ID can be used to correlate log messages from the same thread within a single log as well as generated by the same thread across different types of log files. More information about the thread with a specific ID can be obtained using the cn=JVM Stack Trace,cn=monitor entry. |
| Default Value | true |
| Allowed Values | true false |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
