Message loggers and file handlers

Each properties file contains properties for one or more message loggers. The isLogging property specifies Whether message logs are enabled. To turn on logging for a specific message logger, use:

baseGroup.PDJapp_nameMessageLogger.isLogging=true

To disable logging for a specific message logger, use:

baseGroup.PDJapp_nameMessageLogger.isLogging=false

Associated with each message logger is at least one file handler. A file handler specifies the destination for messages. After message logs are enabled by the message logger, the file handler properties are examined to determine whether to log messages, and if so, how and where. The properties associated with a file handler are:

baseGroup.PDJapp_nameFileHandler.fileName=
baseGroup.PDJapp_nameFileHandler.maxFileSize=
baseGroup.PDJapp_nameFileHandler.maxFiles=

where:

fileName

Fully qualified file name to be used as the base name for message log files. The file can be in any location accessible by the Java™ application.

maxFileSize

Specifies the maximum size, in kilobytes, of each message log file. Default is 512.

maxFiles

Specifies the maximum number of files to be used for message logs. Default is 3.

To specify what classes of messages to log, use the MessageAllMaskFilter.mask property as illustrated in Figure 1.

baseGroup.PDJapp_nameMessageAllMaskFilter.mask=FATAL
 | ERROR | WARNING | NOTICE | NOTICE_VERBOSE
