All OpenFusion Services can produce logging information. This can be used to both track bugs and monitor server operation. OpenFusion uses four basic logging levels: Error, Warning, Information and Debug. The OpenFusion logging system uses the log4j logging package. (See http://jakarta.apache.org/log4j for more information.)
The format used for the logging output. This property is only required if Log Layout is set to Pattern.
Details of setting log patterns can be found in Log Messages.
The layout used for the logging output. Choices are:
If Pattern is selected, the Log Pattern property must be set.
If true, log output is formatted for viewing with LogFactor5. The default is false. The property is only used if the Log Layout property is set to Pattern.
This is the UNIX Syslog facility to which logging is directed. See your UNIX documentation for more information on Syslog facility categories.
This option determines the name of the host to which logging is directed when the Syslog logging plug-in is selected. Syslog output is sent to the local host by default.
This is the number of backup files that are retained after the value of File Maximum Size is exceeded and RollingFile is selected as the logging plug-in. The default is 1.
This option controls whether the existing log file is replaced or new messages are appended to the file.
This is the maximum size of the log file created when RollingFile is selected as the logging plug-in. A new logging file will be created when the value of File Maximum Size is exceeded.
The File Name specifies the file where diagnostic output is saved. A default value is used when this property is not set. This is:
<install_dir>/domains/<domain>/<node>/<service>/log/<service>.log
where <install_dir> is the OpenFusion installation path. See The Object Hierarchy for details of the domains directory structure.
This property determines how diagnostic output will be logged. Options are:
Selecting this option will direct all diagnostic output to a file specified by the Log File property.
This option directs diagnostic output to a file. The output file is backed up periodically when a specific size is reached. See also File Backup Number.
This option directs diagnostic output to the UNIX syslog facility.
This option directs diagnostic output to the NT Event Log.
This option redirects all diagnostic output to the OpenFusion Log Service. A notification-type log is used.
All diagnostic messages are disabled.
This is the identity of the Notify Log that is used when logging to the Log Service is selected. A new log is created when a log with this identity does not already exist.
This property determines the level of diagnostic output that is logged in the log file. The logging level can be changed dynamically. Options are:
Caution: significant amounts of output may be generated when the Debug level of logging is selected.
