rotation-policy

Description
The rotation policy to use for the File Based Debug Log Publisher . When multiple policies are used, rotation will occur if any policy's conditions are met.

Multi-Valued
Yes
Required
Yes
Admin Action Required

sign-log

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 Debug 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


Advanced Properties

asynchronous (Advanced Property)

Description
Indicates whether the File Based Debug Log Publisher will publish records asynchronously.
Default Value
true
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 Debug 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.
Multi-Valued
No
Required
No
Admin Action Required
None. Modification requires no further action

buffer-size (Advanced Property)

Description
Specifies the log file buffer size.
Default Value
64kb
Allowed Values
A positive integer representing a size. Lower limit is 1.
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
